Rational Use Of Water Research Articles

Water rationalization in Brazilian irrigated agriculture

Freshwater, an essential asset for the life of living beings and one of the main resources for the development of nations. About 70% of the freshwater on the planet is used by irrigated agriculture. In view of the increasing population density for food production, considering the limitations of agricultural processes, countless producers are looking for viable alternatives that provide them with greater production, irrigation being one of them. This bibliographic review aims to summarize information on the topic: Rationalization of Water Resources and Environmental Impacts in Irrigated Agriculture, based on searches in books, scientific articles, and publications by reputable organizations related to the topic. In these, aspects related to water scarcity, the challenges of irrigated agriculture, contamination of water resources, the reuse of water for irrigation, the quality of reused water, and adequacy of water for irrigation are dealt with. The need for conservation of water resources and awareness of the irrigator regarding the rational use of water and the environmental impacts inherent to the irrigation process is evident, therefore, the intention is to consolidate increasingly sustainable agriculture.

Study of the Competence of Cadets of Military Universities in the Organization of Rational Water Use and Water Management

The development of environmental and professional competence of future officers is becoming increasingly important along with the improvement of technologies and technical capabilities for the protection and rational use of water resources. The article reveals the methodology and results of the study of the competence of cadets of military universities of the Russian Federation on the issues of ensuring the safety of water bodies by military personnel and ensuring the rational use of water bodies. The relevance of this work is associated with the insufficient implementation of the didactic principle of communication between the theoretical foundations of military ecology taught at the university and practical situations of military service requiring the implementation of measures to ensure environmental safety. Theoretical and empirical research was carried out on the basis of two higher military educational institutions. In the course of the theoretical research, it was found that the environmentalization of education is the leading pedagogical means of forming an environmentally responsible worldview and professional competencies among cadets, which are necessary to effectively ensure the safety of water bodies. The conducted empirical research has established the effectiveness of the environmental education system, built on the basis of a methodological model for the implementation of environmental management principles. The introduction of the proposed model into the education system in higher military educational institutions contributes to the environmentalization of the educational environment of the educational institution; the inclusion of cadets in the most diverse types of environmental activities; preparation for ensuring environmental safety in the performance of official duties; implementation of measures for the protection and rational use of water resources. This article may be of interest not only for teachers of military universities and commanders who carry out educational work with personnel, but also for teachers of technical universities interested in the issues of environmentalization higher education, as well as for technosphere safety specialists for educational and other informational work.

AGRICULTURAL WATER MANAGEMENT PRACTICES IN MENA REGION FACING CLIMATIC CHALLENGES AND WATER SCARCITY

Location of Tunisia between the Mediterranean and the Sahara, is an arid country on a major part of its territory. This aridity combined with variability Mediterranean climate makes water a resource both scarce and irregularly distributed in time and space. Tunisia is classified by international organizations as being among the least endowed with groundwater resources countries in the Mediterranean basin. To improve modernization policy in the agriculture sector in Tunisia, essential factors for saving water and for a sustainable development must be followed as providing farmers with the technology they need to maximize the efficiency and rational use of water to optimize the use of water in agriculture. The subsurface irrigation has several advantages in terms of saving the amount of water in a sustainable development that aims to protection of groundwater. The aim of the contrasting water management techniques described in this paper is to minimize spatio-temporal losses. Subsurface irrigation can increase stores water in the root zone, allows limiting losses by evaporation and percolation. It also helps reduce weed growth. Then, we have carried out studies on the following irrigation systems: subsurface drip irrigation system (SDI) and Buried diffusers (BD). The studies consisted of monitoring the water saving of each of these techniques as well as their effects on the profitability of different crops. For example, SDI was used for two treatments full irrigation (T1) and deficit irrigation with 50% of crop Evapotranspiration (T2). Soil water content (SWC) variation was more important at the end of the season due to root uptake and hard climatic condition, treatment T2 had less water stock and best water use efficiency with 10.83 kg/ha than 5.85 kg/ha for T1. While the average values of the SWC are 19.6 ± 2.68; 15 ± 3.81 and 14 ± 3.72% respectively for buried diffuser with full irrigation TD100, deficit irrigation with 50 TD50 and deficit irrigation with 25% TD25.

Quantification of Forage Evapotranspiration Dynamics Cultivated in the Southern Amazon with SIMDualKc Model

Studies of the dynamics of water in the Soil-Plant-Atmosphere system have been constantly studied, as they directly contribute to the increase in production and the rational use of water for the most diverse cultures. In this approach, the aim of the study was to assess the water demand in forage Urochloa decumbens, with application of the SIMDualKC model. The meteorological variables used in the paper were obtained by an automatic INMET station. And to estimate forage production, cuts were made at a height of 15 cm, then removing it, simulating cattle grazing. Each cut was determined to accumulate degree-days and the base and cut temperatures were 10°C and 30°C, respectively. For the dynamics of crop water demand, the SIMDualKc model was used, in a daily time interval to estimate the basal crop coefficient (Kcb), evaporation coefficient (Ke), crop evapotranspiration (ET), in addition to Kc and the water available in the soil in the forage growing cycle. Kcb and Ke had an inverse relationship, which means that when Kcb increased, Ke showed a decreasing trend. The Kc values did not change until the 3rd cut, but in the 4th cut there were changes with a reduction in rainfall and water availability in the system. It is observed that the model showed good ability to estimate the amount of water available in the soil, in addition to the physiological attributes of the forage, being a great option in the study of water dynamics for the forage.

Urbanization processes lead to an increase in water use and its contamination. The strengthened anthropogenic impact has caused an unfavorable situation in the hydrosphere in almost all regions of Ukraine. Amidst constant anthropogenic load and intensive change of the living environment due to urbanization processes, measures reducing the level of pollution of wastewater, groundwater, and atmospheric air come to the fore. The article systemizes the factors of anthropogenic impact on water use safety, namely: wastewater of atmospheric and industrial origin, groundwater pollution, acid precipitation, and an increase in technogenic sediments that are formed during the operation of industrial and economic facilities, etc. It is also noted that the major problems of urbanized areas are high air pollution and deterioration of water supply and sanitation infrastructure. They result in a deterioration of the quality of water resources, a growth of atmospheric air pollution, the number of anthropo-genic sediments, and diffuse pollution of the environment. The directions of minimizing the negative impact of anthropogenic sediments, air pollution, surface contaminated runoff from urban areas on the quality of water in water bodies and their ecological state are substantiated. The urbanization of territories causes an increase in the volume of wastewater from all water users, both individual citizens and enterprises of industry, housing and agriculture. Despite the different technologies of wastewater treatment, a great deal enters the environment without treatment due to the growing number and overloading of treatment plants. The directions of minimizing the negative impact of surface contaminated runoff from urban areas on the quality of water in water bodies and their ecological state are systematized. Measures of rational water use are proposed, in particular: reduction of water consumption in urbanized areas as a result of the use of a system of economic tools, resource-saving technologies; strengthening control over the discharge of industrial waste; use of low-waste technologies and water recycling; establishment of standards for wastewater discharge; creation of water protection zones in areas of groundwater supply and intake, etc.

МІСТОБУДІВНИЙ АСПЕКТ ПРАВА ЛЮДИНИ НА БЕЗПЕКУ

Research in many fields of modern science is devoted to issues of human safety and security. The human right to security is undeniably fundamental and inalienable. Human security and the human right to security are interdisciplinary, even general scientific concepts. But today there is no more or less established definition of these concepts, so more and more researchers are studying this issue. Human existence takes place in a certain environment: natural and anthropogenic. Urban planning activity is the activity thanks to which the environment of human life is created. For the survival and effective development of a person, this environment must first of all be safe, that is, one in which a person will have the opportunity to exercise his rights, fulfill his duties and effectively satisfy his needs. That is why the study of the issue of the human right to security in this sphere of social relations becomes particularly relevant. Also taking into account the entire burden of the Soviet urban planning heritage, the need to restructure the economic base, stabilize the man-made burden of the regions, improve the settlement system, develop social and engineering transport networks, ensure the rational use of land, form a national ecological network, implement rational water use, preserve historical and cultural heritage and the prospect of post-war reconstruction of the country, the issue of ensuring the human right to security can be called fundamental in the field of solving these problems. The study of this problem, the development of a conceptual apparatus will provide an opportunity to substantiate the need to reformat the state urban planning policy and shift its focus to the needs of modern man, especially to his need to create a safe, full- fledged living space, and to propose making the necessary changes to the current legislation.

УПРАВЛЕНИЕ ВОДНЫМ РЕЖИМОМ ПОЧВЫ КУЛЬТУР СЕВООБОРОТНОГО УЧАСТКА В ЗАВИСИМОСТИ ОТ ПОГОДНЫХ УСЛОВИЙ НА ОРОШАЕМЫХ ЗЕМЛЯХ САРАТОВСКОЙ ОБЛАСТИ

Due to significant global climate change, which leads to a mismatch between the requirements of plants and environmental conditions, the most relevant at present is the placement of crops in places where the reclamation regime (culture requirements for environmental conditions) coincides with environmental conditions in a given place. The manifestations of global climate warming in the Saratov region are expressed in a decrease in the amount of precipitation falling during the main growing season of agricultural crops (May-July), which, against the background of rising air temperature, increases the discrepancy between moisture resources and the need for plants, which leads to large fluctuations in agricultural yields. cultures. Therefore, in the production of agricultural crops, farming systems and crop rotations should be based on agroecological principles, providing for high yields, reproduction of soil fertility, environmentally friendly products, efficient and rational use of irrigation water, which will provide economic efficiency, and serve to restore the ecological balance in the region. An analysis of the current state of irrigated agriculture shows that the possibility of increasing agricultural production is not fully used. Irrigation efficiency is largely reduced due to a violation of the complex of agrotechnical and agro-ameliorative measures, the lack of reasonable crop rotations, non-fulfillment of irrigation plans, insufficient application of organic and mineral fertilizers, as well as the current natural and climatic changes and a number of other reasons. Only the observance of a high culture of agriculture in combination with the whole complex of land reclamation measures will make it possible to obtain high yields of grain and other crops in the Saratov region.

Experiments and Application of Reclamation of High-Mineralized Mine Wastewater for Confecting Grouting Slurry.

Owing to the high mineralization and high treatment cost, Ordovician limestone water is often regarded as a mine wastewater. In order to make rational use of mine water with high mineralization and turn waste into treasure. In this work, the natural water quality of Ordovician mine water in the Weibei coalfield had been tested, and the suspended matter and trace elements of Ordovician mine water in the selected deep detained area had been further tested. As a contrast, the water quality of Ordovician mine water after heating and concentration had been tested. The mechanical and hydraulic parameters of concentrated mine water-loess and concentrated mine water-cement slurry had been tested and compared with conventional slurry. The results showed characteristics of deep detained Ordovician limestone mine water is high salinity, certain suspended matters, limited special material and high permanent hardness. However, compressive strength of loess samples increased, while the permeability reduced. The initial setting-time of the modified material was short, while it showed an increased compressive strength. In practical terms, the quantity of grouting produced in engineering applications can be reduced by 16%, whereas the discharge of high-mineralized mine water can be decreased by about 40,000 m3/a.

A new innovative irrigation method for wood, shrub crops and grapes

The article analyzes the main disadvantages of traditional methods of watering woody, shrubby fruit, ornamental crops and grapes and suggests a new innovative way of watering them. According to the principle of implementation, it belongs to the group of subsurface irrigation and is a new version of them. There is a wide list of positive qualities of the new irrigation method that allow for much more rational use of irrigation water but create more favorable conditions for the growth and development of watered plants. A description of its design features and methods of implementation is given. The proposed new jet-pit irrigation method is not inferior in its technical capabilities to the most modern irrigation method – drip, but it is much cheaper and more reliable than the latter.

Effects of muddy water irrigation with different sediment gradations on nitrogen transformation in agricultural soil of Yellow River Basin

Muddy water irrigation has been widely practiced in the Yellow River Basin for agricultural production and is an important method of economical and intensive utilization of water resources. In this study, the effects of sediment gradation, sand content, and soil moisture content on nitrogen (N) transformation were studied through a series of experimental tests. The results indicated that muddy water irrigation significantly affected agricultural soil physical and biological properties as well as N transformation. Soil bulk density, total porosity, pH, and microbial enzyme activities significantly correlated with N transformation as affected by the interaction between sediment and soil moisture. Sediment addition generally increased the soil bulk density and reduced the soil porosity and pH significantly, and the optimum moisture for promotion of the N transformation rate was 80% of the water-filled pore space. Therefore, muddy water irrigation has a potentially long-term influence on agricultural N cycles in semi-arid regions of northwestern China. This could provide a theoretical basis for scientific and rational use of muddy water for irrigation.

Potential reduction in drinking water consumption at the headquarters of the Regional Electoral Court of Pernambuco - TRE/PE

Water conservation in buildings includes not only reducing the demand for potable water, but also adopting alternative sources for activities with less noble purposes. Public buildings under the jurisdiction of the Federal, State, and Municipal governments are required to promote actions aimed at the rational use and conservation of water, according to the responsibility established in the Environmental Agenda in Public Administration.In light of the above, this study aims to analyze the potential for reducing drinking water consumption at the headquarters building of the Electoral Regional Court of Pernambuco - TRE/PE through the use of alternative water sources, such as rainwater and condensed water from air conditioners. The methodology began with the characterization of the study site and the consumption of potable water.Subsequently, the technical and economic feasibility of rainwater and condensate water use was investigated, as well as a comparison between the proposed measures. The results obtained indicate that the techniques studied are beneficial, presenting significant potential for reducing the consumption of potable water that would be used for toilet flushing, 63% for rainwater use and 62% for condensate water.In addition, they can also provide annual financial savings of R$8,216.01 and R$8,045.74, respectively. Thus, besides reducing drinking water consumption, the proposed measures also promote the minimization of financial costs, whose capital can be used in the search for continuous improvement of services provided to society.

Management of groundwater resources in transboundary territories (on the example of the Russian Federation and the Republic of Estonia)

Groundwater, as a source of water supply, the most important mineral and geopolitical resource, , is often the only source of high-quality drinking water that is protected from pollution under conditions of increasing deterioration of surface water quality. Transboundary groundwaters are the focus of hydrogeological researchers for a number of reasons, including the reduction and pollution of water resources as a result of economic activities. The increased controversy between states over transboundary water issues has necessitated the development of international legal documents on issues related to water conflict prevention and the sustainable use of fresh water. As part of the analysis of the problem of legal regulation of groundwater extraction from transboundary aquifers and complexes, it is proposed to consider this aspect on the example of Russia. The problems of regulation of rational use and protection of fresh water in the bilateral treaties of the Russian Federation were revealed; a methodology for the management of groundwater extraction in the territory of the transboundary aquifer was developed, the size, parameters, and factors influencing the formation of the transboundary zone have been determined (based on research and analysis of water intake activities in the border areas of the Russian Federation and the Republic of Estonia) were determined.

Validation of Applying Simulation Models for Different Irrigation Systems: Review Article

In Egypt, agriculture is shaped by two goals. The first goal is maximum national production per unit area and the second goal is maximum production per cubic meter of water. Therefore, this strategy relates the utilization of national resources, soil and water, and to do this in a proper way we need tools and technologies which will allow to develop these resources in a suitable manner. The design and managing of irrigation systems must have its base in criteria that are relevant, which implies to take into account agronomic, soil, hydraulic, economic, energetic, and environmental factors. The optimal design and managing of irrigation systems at farm level is the first important factor for a rational use of water, economic development of agriculture and its environmental sustainability. Computer simulation models have the potential to improve the efficiency of irrigation systems and thus deliver significant water savings. This can be achieved by optimizing the design and management decisions at the field level. Irrigation simulation models are useful tools both at the design and management stages of irrigation systems. When used for irrigation design purposes, simulation models help to optimize irrigation variables such as field slope, length of the field and the design flow rate...etc. These models can aid the designer in making decisions as to the appropriate values of variables that produce the best performance. This is mostly applicable to newly established fields or when converting from one irrigation system to another. In the majority of the irrigation simulation models currently in use, previous field characteristics are used to optimize future irrigations. However, numerous researchers have established that these characteristics change both with time and space, and hence the accuracy of such models may be affected. Therefore, the aim of this article is to analyse knowledge and investigations that enable to identify the principal criteria and processes that allow improving the design and managing of the irrigation systems, based on using irrigation systems simulation models to develop agriculture more efficient and sustainable, as well as using them as a tool for farmers, researchers, and decision makers.

Permeable Pavements as a Means to Save Water in Buildings: State of the Art in Brazil

Permeable pavements have been the subject of numerous studies in recent decades. The possibility of dissipating stormwater more smoothly and generating numerous benefits to the environment and users makes the use of permeable pavements an excellent possibility of integration into sustainable and resilient water management systems in cities. In Brazil, numerous studies on the quantity and quality of infiltrated water, permeability of the coating, clogging, environmental burden, and feasibility, among other characteristics, have been researched. Within this theme, the Federal University of Santa Catarina (UFSC) has contributed with ten papers in the research of permeable pavements in the last six years, which address various topics about the effectiveness and applicability of permeable pavements. This paper reviews the studies conducted at UFSC on permeable pavements and discusses the different results within the main issues found. In general, the selected documents addressed seven themes in the studies: potential for potable water savings, clogging, quantity and quality of the water infiltrated into the pavement, Life Cycle Assessment (LCA) and its variants, and hydraulic and structural design details. More specifically, many selected papers assess the potential use of stormwater harvested through permeable pavements in non-potable uses of buildings. The possibility of aligning the benefits of green infrastructure with the rational use of water expands the advantages of the system and can help prevent future water scarcity, as well as reduce the environmental impacts of paving.

Impacts of Desalinated and Recycled Water in the Abu Dhabi Surficial Aquifer

In Abu Dhabi, one of the most arid regions in the world, in recent decades, desalinated water has been identified as a prime solution in solving the water demand issues. In this study, a three-dimensional coupled density-dependent flow and solute transport model was set up in order to study the effect of the artificial recharge using desalinated water and the influence of nonconventional water with a salt concentration in the range 0.1–2 g/L The results confirm that this region demands the adoption of a more rational use of irrigation water or additional usage of desalinated water and recycled water together with optimizing groundwater pumping at locations that are vulnerable to further quality degradation and depletion. The long-term storage of desalinated freshwater with a maximum radial distance of 653 m in the dune surface is ensured with the formation of the transition zone, and change in the groundwater head up to 5 km. The maximum recovery obtained by immediate recovery is 70%. The study expresses the long-term feasibility of desalinated freshwater storage and the need for further management practices in quantifying the contribution of desalinated and recycled water for agriculture activities which might have improved groundwater quality and increased hydraulic head at some locations.

Green Restaurants ASSessment (GRASS): A Tool for Evaluation and Classification of Restaurants Considering Sustainability Indicators

Green restaurants are based on the implementation of environmental management and are closely related to quality management through a set of instruments and programs. This study aimed to build an instrument classification adopting cutoff points and classify restaurants using traffic light scores from the sustainability assessment checklist validated in Brazilian Portuguese for restaurants. The questionnaire classification validation was performed using a cross-sectional study conducted in a convenience sample of 97 restaurants. The instrument has 76 items, and all items were based on yes/no/not applicable answers, comparing sustainability activities. The instrument score was obtained by assigning one point to each “yes” item. Each section received a score, and a total score was provided to the restaurant from the three sections’ sum. International instruments used in the checklist development stage were checked to assist in the cutoff points determination. Therefore, the score for restaurants with low adherence to sustainable practices or red seal ranges from 0 to 40%, restaurants with medium adherence to sustainable practices or yellow seal from 40% > to <75%, and restaurants with good adherence to sustainable practices or green seal ≥75%. The instrument is divided into three sections (1. water, energy, and gas supply; 2. menu and food waste; 3. waste reduction, construction materials, chemicals, employees, and social sustainability). Percentages must be reached in all sections. Researchers did not find any green or sustainable restaurants through the checklist application in the tested sample, and 47.4% of the restaurants had the yellow seal (presenting sustainable activities) with higher scores for Section 2 regarding menu and food waste. The items less scored were the company has goals for the rational use of water, the company achieves zero greenhouse gas emissions with proven partnerships, the company has a documented program to reduce carbon emissions, and towels or uniforms are made of organic or sustainable material. Thus, it demonstrates the attention points and improvements in the analyzed restaurants. We hope that the construction and validation of the checklist and its score’s determination have contributed to broadening the discussions on sustainability in food services and serve as a starting point for future research. Strategies like these are fundamental to improve the understanding of the subject and to expand the knowledge of nutritionists who deal directly with this economic sector.

Mathematical model for forecasting the irrigation rate of agricultural crops

The paper presents the results of studies of mathematical relationships between the irrigation rate and the sum of positive temperatures, which makes it possible to optimize and rationalize the use of natural resource potentials without compromising the productivity of forage crops. The dynamics of soil moisture during the growing season on sierozemic soils in the south of Kazakhstan with a sum of positive temperatures above 10 ° C has been established. The carried out mathematical analyzes of the irrigation regime for corn in the southern zone of Kazakhstan gives reason to believe that in the current natural and economic conditions, it is necessary to introduce into the structure of sown areas demanded in the food market of agricultural crops, aimed at the rational use of land and water and natural resources.

Покращення технології забору дренажних вод, які фільтруються з водосховищ, та їх використання

Goal. To offer the improved technology of water intake by systems of anti-filtration protection of territories against flooding from reservoirs and preparation of drainage waters for water use. Methods. Analytical-synthetic — for the analysis of modern scientific research and development of measures to improve the technology of water intake by anti-filtration curtains from flooding from reservoirs; statistical — for the analysis of parameters of a technological process; calculation — to create a simulation model of the anti-filtration curtain with vacuum siphon technology of water intake. Results. To improve the ecological condition of the territories located in the zones of influence of the Dnieper reservoirs, it is proposed to improve the design and technological parameters for vertical drainage systems. The main attention is paid to anti-filtration systems with airlift drainage from drainage wells, in particular the protection of the territory of Kamianskyi pod (area 6400 ha), located on the left bank of the Kakhovka reservoir. It is proposed to improve the anti-filtration systems by replacing the airlift technology of water intake from wells with a vacuum siphon to avoid clogging of the filters. According to the results of modeling according to the author’s method of calculation of vertical drainages with siphon drainage of filtration waters from wells, 3 different variants of anti-filtration curtains for hydrogeological conditions of Kamianskyi pod are presented. It is also proposed to use the drainage water, after proper preparation, to meet local water needs to avoid losses associated with its transportation over long distances. The ratio of daily human water use for sanitary, household, and drinking needs is considered. Conclusions. For rational water use, they proposed the use of groundwater, which causes flooding of areas adjacent to reservoirs, and pumped back to reservoirs, to use to meet different water needs. That is, use anti-filtration curtains as infiltration water intakes and return water after use and treatment to reservoirs.

SOIL ATTRIBUTES UNDER DIFFERENT WATER MANAGEMENT SYSTEMS OF RICE PADDIES IN THE AMAZONIAN SAVANNA OF BRAZIL1

ABSTRACT The rational use of water while considering the increases in food production is a great challenge for agriculture currently. The aim of the present study was to evaluate the soil properties of rice paddy areas under different water management systems. For this, the rice cultivars BRS Tropical and IRGA 424 were grown under the following treatments: M1: Intermittent flooding; M2: Intermittent flooding, followed by continuous flooding; M3: Continuous flooding, followed by intermittent flooding; and M4: Continuous flooding for the entire plant cycle. As a control, a non-cultivated area, adjacent to the experimental plots was also evaluated. The variables analyzed were P, K+, Ca2+, Mg2+ and Al3+ contents, pH, soil organic carbon (SOC), total nitrogen (TN) Carbon Stock (C-Stock), nitrogen stock (N-Stock), Cation-exchange capacity (CEC), C/N ratio; CO2 emission, soil microbial biomass carbon (SMB), metabolic coefficient (qMic) and acid phosphatase and urease activities. There was not difference among the different water management systems for P, K+, Mg2+, CEC and C/N ratio. The SMB and the acid phosphatase and urease activities were lower under the different treatments when compared to the control. The CO2 emission under rice paddy system was influenced by the phenological phase of the crop. The variables SOC, C-Stock, SMB, C/N ratio, K+, acid phosphatase and usease activities are those most sensitive attributes observed in the soil under different water management systems during rice cultivation. Water management in the rice paddy system influenced soil by changing its quality.

Soil Hydrology Process and Rational Use of Soil Water in Desert Regions

There is a balanced plant–water relationship in the original vegetation in the desert area. With the increase in the population and social development of the desert area, people need the goods and services of the forest vegetation ecosystem. To meet the growing demand for plant community goods and services, more original vegetation has been changed into non-native vegetation, such as in the Loess Plateau in China. However, with the plant growth, sometime soil drying happens and becomes gradually serious with time in most desert regions. Serious drying of soil eventually results in soil quality degradation, vegetation decline, and crop failure, which influence the produce and supply of forest vegetation goods and services in the market in dry years or waste of soil water resources in wet years, which wastes precious natural resources. In order to use soil water rationally, soil water must be used in a sustainable way and the plant–water relationship has to be regulated for the Soil Water carrying capacity for vegetation in the key period of plant–water relationship regulation to carry out a sustainable use of natural resources, high-quality sustainable development of forest and grass, and high-quality production of fruit and crops in desert regions.
