The Influence of Climate Perception and Low-Carbon Awareness on the Emission Reduction Willingness of Decision Makers in Large-Scale Dairy Farming: Evidence from the Midwest of Inner Mongolia, China

In recent years, global climate change has profoundly influenced natural ecosystems and human societies, making climate mitigation and carbon emission reduction a point of consensus among the international community. The issue of carbon emissions in agriculture, particularly in the livestock sector, is garnering increasing attention. This study focuses on large-scale dairy farms in the central and western regions of Inner Mongolia, exploring their low-carbon production behavioral intentions and influencing factors. By constructing a structural equation model (PLS-SEM), we systematically analyze the relationships between variables such as climate perception, value judgment, attitude, subjective norms, and perceived control and their combined effects on low-carbon production behavioral intentions. The findings suggest that the influence of climate perception and low-carbon awareness is mediated. Thus, the stronger the farm owners’ perception of climate change, the more they recognize the value of low-carbon production and the greater the social pressure they experience and their sense of self-efficacy. The farm owners’ attitudes, perceptions of social norms, and evaluations of their own capabilities collectively determine their intentions regarding low-carbon production. Furthermore, multi-group analysis showed significant heterogeneity in behavioral intentions between different scales of dairy farms. Small-scale farms, due to their weaker economic capacity, tend to harbor negative attitudes towards low-carbon production, while large-scale farms, with greater economic power and sensitivity to policy and market demands, are more likely to take low-carbon actions. This study provides theoretical support for formulating effective low-carbon policies, contributing to the sustainable development of the livestock sector and agriculture as a whole.

清康雍乾时期内蒙古中西部地区山林开发与林权问题探析

During the Qing dynasty, the wood tax was a non-negligible part of the source of customs duties of the imperial court, therefore, the nationwide mountain and forest exploitation activities carried out by both the official supervision as well as the local and social businessmen and citizens were very active. In the wave of resource exploitation and utilization, the Mongolian Banner Mountain products, which were still under the domain of Mongolia, had also been stolen and sold, becoming a “special area” under the situation of banning. There are countless discussions of different dimensions on the mining process as well as the banning and unbanning time of Daqing Mountain and Muna Mountain forests in the central and western regions of Inner Mongolia. However, it is still necessary to discuss in depth about how the imperial court handled the mining, transportation and sale of the mountain forests in this area under the “blocked” state. In other words, why did the Qing court strictly impose a policy of banning the border areas while allowing the smuggling and selling of mountains and forests to occur, and even the official supervision and commercial office of felling and transporting wood plants in the Muna Mountains. In addition, during the process of mining and selling mountain wood vegetation, the ownership right of its mountain forest has gradually formed in the unique form of “boundary” or “the forbidden”, which has become a unique form of mountain forest ownership in Mongolia. Among them, the process of temples in Mongolia region confirming the rights to the surrounding mountains and forests is clearer than that of the local society or the country, which fully demonstrates its unique nature.

Analysis of the Sand Erosion Effect and Wear Mechanism of Wind Turbine Blade Coating

The wind–sand climate prevalent in the central and western regions of Inner Mongolia results in significant damage to wind turbine blade coatings due to sand erosion. This not only leads to a decline in power generation but also poses safety risks. This study replicated the wind–sand environment of Alashan and numerically simulated the erosion and wear process of the blade coatings of a 1.5 MW horizontal axis wind turbine under rotational conditions using the DPM model. Additionally, erosion tests were conducted on the operating wind rotor in a wind tunnel. The simulation results demonstrate that sand particle trajectories in the rotating domain are influenced by vortex, incoming wind speed, and sand particle size. For small-sized sand particles, variations in wind speed do not substantially alter the number of particles in contact with the wind turbine blades. However, alterations in the momentum of these particles lead to changes in the impact force on the coating surface. Conversely, the change of wind speed will not only alter the number of large-size sand particles in contact with the wind rotor but also modify the impact force on the coating surface. Furthermore, after impacting the blade, small sand particles continue to move along an approximate helical trajectory with the airflow, while large-size sand particles swiftly rebound. Through statistical analysis of erosion pits on the blade surface after the erosion experiments, it was observed that, in comparison among the leading edge, windward side, trailing edge, and leeward side, the leading edge presents the greatest number of erosion pits, whereas the leeward side has the fewest. Along the spanwise direction, the 0.7R-blade tip segment exhibits the highest count, while the blade root-0.3R section displays the fewest number of pits. The wear morphology of the blade coating was observed from the blade root to tip. The leading edge coating exhibits a range from shallow pits to coating flaking and deeper gouge pits. On the windward side, the coating displays wear patterns varying from tiny cutting pits to cutting marks, and then to gouge pits and coating flaking. Erosion morphology of the trailing edge evolves from only minor scratches to spalling pits, further deepening and enlarging. These research findings provide a basis for the study of zoning-adapted coating materials for wind turbine blades in wind–sand environments.

Five-dimensional assessment of China's centralized and distributed photovoltaic potential: From solar irradiation to CO2 mitigation

Owing to China's escalating demand for renewable energy and carbon emissions reduction, and given its prominent position as one of the fastest-growing nations in photovoltaic (PV) development, a comprehensive assessment of the potential of both centralized and distributed photovoltaic systems in China is crucial. However, current research on PV potential assessment presents several challenges. Therefore, this study presents a five-dimensional assessment model, encompassing geographical, technical, economic, CO2 mitigation, and realizable potential, to systematically map China's centralized photovoltaic (CPV) and distributed photovoltaic (DPV) potential. The findings underscore the vast PV potential across the country, with areas of 3.11 million km2 and 252.72 thousand km2 deemed suitable for CPV and DPV development, respectively. This corresponds to a technical potential of 416,383.27 and 28,261.53 TWh/yr for CPV and DPV, respectively. Furthermore, this study explored the economic potential of CPV and DPV, revealing that the generation costs of both CPV and DPV in China are in proximity to the feed-in tariffs. With technological advancements and economies of scale, a broader PV potential is projected to be economically feasible by 2030. Full implementation of the current economic potential can yield an annual CO2 mitigation of 54.20 and 8.39 gigatonnes (Gt) using CPV and DPV, respectively. Notably, China's PV potential exhibits distinct regional heterogeneity, with CPV potential concentrated primarily in the western region and DPV potential distributed predominantly across the eastern provinces. This study identified the most resource-intensive areas in the western region of Inner Mongolia for CPV and in the coastal regions of Guangdong and Shandong provinces for DPV. Considering policy imperatives and the development status, China's PV sector holds tremendous potential to significantly contribute to carbon reduction targets. Based on the findings, policy recommendations are proposed, emphasizing the imperative of jointly developing CPV and DPV systems, as well as implementing phased and planned growth strategies for PV growth.

A Study on the Spatial-Temporal Evolution and Driving Factors of Non-Grain Production in China's Major Grain-Producing Provinces.

Food self-sufficiency in a large country with 1.4 billion people is very important for the Chinese government, especially in the context of COVID-19 and the Russian-Ukrainian conflict. The objective of this paper is to explore the spatial-temporal evolution and driving factors of non-grain production in thirteen major grain-producing provinces in China, which account for more than 75% of China's grain production, using 2011-2020 prefecture-level statistics. In the present study, the research methodology included GIS spatial analysis, hot spot analysis, and spatial Durbin model (SDM). The findings of this study are as follows: (1) The regions with a higher level of non-grain production were mainly concentrated in the central and western regions of Inner Mongolia, the middle and lower reaches of Yangtze River and Sichuan, while the regions with a low level of non-grain production were mainly distributed in the Northeast Plain. The regions with a higher proportion of grain production to the national total grain production were concentrated in the Northeast Plain, the North China Plain, and the Middle and Lower Yangtze River Plain of China. The hot spot regions with changes in non-grain production levels were mainly distributed in the Sichuan region and Alashan League City in Inner Mongolia, and the cold spot regions were mainly distributed in Hebei, Shandong, Henan, and other regions. (2) An analysis of the SDM indicated that the average air temperature among the natural environment factors, the ratio of the sum of gross secondary and tertiary industries to GDP, the ratio of gross primary industry to the GDP of economic development level, the urbanization rate of social development, and the difference in disposable income per capita between urban and rural residents of the urban-rural gap showed positive spatial spillover effects. The grain yield per unit of grain crop sown area of grain production resource endowment, the total population of social development, and the area sown to grain crops per capita of grain production resource endowment all showed negative spatial spillover effects. The research results of this paper can provide a reference for the country to carry out the governance of non-grain production and provide a reference for China's food security guarantee.

Complex ecological and socioeconomic impacts on medicinal plant diversity.

Medicinal plant diversity (MPD) is an important component of plant diversity. Over-collection based on medicinal and economic value has the potential to damage the stability of the regional ecosystem. It is important to understand the current distribution of MPD and the factors influencing it. However, it is still unclear whether environmental and socioeconomic conditions have an impact on their distribution. We selected the Inner Mongolia as a representative study area which covers a wide area, accounting for 12.29% of China's national land area and 0.79% of the world's land area. At the same time, the region is a long-standing traditional medicinal area for Mongolians in China. Therefore, the region is significantly influenced by changes in environmental factors and socio-economic factors. We used 9-years field survey of the distribution of medicinal plants in Inner Mongolia for assessing the distribution of MPD as influenced by environmental and socioeconomic activities by combining spatial analyses, species distribution models, and generalized additive models. The results from the spatial analysis show that the western region of Inner Mongolia is the main cold spot area of the MPD, and the central-eastern and northeastern regions of Inner Mongolia are the main hot spot areas of the MPD. At the same time, the distribution of cold spots and hot spots of MPD is more obvious at large spatial scales, and with the refinement of spatial scales, the cold spots in scattered areas are gradually revealed, which is indicative for the conservation and development of MPD at different spatial scales. Under the future climate change of shared socioeconomic pathways (SSP), areas with high habitat suitability for medicinal plants remain mainly dominated by the Yellow River, Yin Mountains, and Greater Khingan Range. Notably, the SSP245 development pathway remains the most significant concern in either long- or short-term development. The nonlinear relationship between the driving factors of MPD at different spatial scales shows that temperature, precipitation and socioeconomic development do have complex effects on MPD. The presence of a certain temperature, altitude, and precipitation range has an optimal facilitation effect on MPD, rather than a single facilitation effect. This complex nonlinear correlation provides a reference for further studies on plant diversity and sustainable development and management. In this study, the spatial distribution of medicinal plant resources and the extent to which they are driven by ecological and socioeconomic factors were analyzed through a macroscopic approach. This provides a reference for larger-scale studies on the environmental and socioeconomic influences on the distribution of plant resources.

Exploration on the Ecological Restoration Path of Hulestai

The contradiction between ecological environmental protection and economic development has been plaguing all walks of life. The process of balancing the two and finding the optimal solution is still under exploration. This study is based on the method of field investigation to investigate the semi-agricultural and semi-pastoral area of Hulestai. The ecological problems reflected by Hulestai include the decline of grassland production capacity and the intensification of desertification. The main reasons for this are the shrinking of grassland area due to reclamation, the destruction of mountain vegetation caused by mining and excavation, and the decline in the ability of pasture regeneration due to overload grazing and predatory operations. Therefore, it is necessary to solve the ecological and environmental problems of Hulestai through the anti-grazing policy, the control of grassland desertification in accordance with the law, and using blockchain technology to connect industries with farmers and herdsmen to develop the economy. The case of Hulestai can reflect the overall environment of the pastoral areas in western Inner Mongolia to a certain extent, so the relevant measures are also applicable in the central and western regions of Inner Mongolia.

Characterization of drinking groundwater quality in rural areas of Inner Mongolia and assessment of human health risks

Groundwater is an important natural resource of drinking water in rural areas in Inner Mongolia, China. In this study, 4438 drinking groundwater samples were collected from the rural areas of 81 counties in Inner Mongolia, and were analyzed for 16 parameters, including pH, total hardness (TH), chemical oxygen demand (COD), total dissolved solids (TDS), sulfate (SO42-), chloride (Cl-), fluoride (F-), iron (Fe), manganese (Mn), arsenic (As), cadmium (Cd), hexavalent chromium (Cr), lead (Pb), aluminum (Al), cuprum (Cu), zinc (Zn). The groundwater quality was evaluated with water quality index (WQI) and human health risk assessment (HRA). Monte Carlo simulation were applied for the uncertainty and sensitivity analysis in the health risk assessment. The spatial map was employed based on the inverse distance weighted (IDW) interpolation technique. The results reveal that while the hazard quotient (HQ) suggests that the risk of single element contamination is feeble, the hazard index (HI) indicates a potential health risk for the local population. The observed cumulative carcinogenic risk (CCR) indicates a probable risks of carcinogenic health hazards in the study area. The sensitivity analysis revealed that daily ingestion rate (IR), exposure frequency (EF), and the concentrations of As, Mn, F-, and Cr are the most influential parameters for health hazards. The highly polluted areas are mainly distributed in the central and western regions of Inner Mongolia, including Xianghuangqi, New Barag Zuoqi, and Togtoh. It is observed that the groundwater may cause a potential health risk after long-term ingestion. The results of this study will contribute to groundwater management and protection in Inner Mongolia.

Study on SO3 emission test of typical ultra-low emission coal-fired units in western region of Inner Mongolia

To study the effect of types of boilers, pollutant treatment facilities and coal quality on SO3, emission concentration of SO3 was tested by controlled condensation method for seven typical ultra-low emissions coal-fired units in western region of Inner Mongolia. The test results showed that the SO3 emission concentration of all units ranged from 0.36 mg/m3 to 2.04 mg/m3, much lower than 5 mg/m3, so there was no need to add SO3 removal facilities. For the units burning the coal of same sulfur content, which adopt LLTESP and WESP has the lower SO3 emission concentration. The SO3 emission concentration can also be controlled at a lower value when SNCR and double-tower double-cycle WFGD technology are adopted in the unit burning medium-high sulfur coal.

Meteorological Risk Assessment of Rooftop Solar Resource Development in Inner Mongolia

Due to the long and narrow regional characteristics of Inner Mongolia, there are obvious climatic differences between the east and the west, and various meteorological factors have different influences on the development and utilization of solar energy. The abundance and stability index of solar energy resources are relatively high in the central and western region of Inner Mongolia, but there are more sandstorms, high temperature and strong wind. The eastern region is greatly affected by cloud cover, relative humidity and snowfall, which weakens the solar radiation. Through the comprehensive evaluation of the solar energy resources and meteorological elements, it is found that from the Alashan League to the west of Xilin Gol League, and the most of the Chifeng City are low-risk areas, which are relatively suitable for the development and utilization of rooftop solar energy. The central and northern areas of hulunbuir are high-risk areas, which is not suitable for that. Based on the meteorological industry standard “Solar Energy Resource Assessment Method”, we calculate the solar energy resources abundance and stability index, combined with the annual surface meteorological data of 119 meteorological stations in Inner Mongolia from 1988 to 2018. The distribution characteristics of solar energy resources and meteorological elements in Inner Mongolia is analyzed and the suitability and meteorological risks of rooftop solar resources development and utilization are evaluated.

The bacterial abundance and community structure of 170 soil samples collected from the western region of Inner Mongolia were tested using polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE), and the correlation between bacterial community and soil fertility parameters was analyzed. The results showed that the diversity of bacteria in the western region of Inner Mongolia was relatively rich. The richness index was between 4 and 60 and the Shannon index was between 1.38 and 4.09. There were significant differences in the diversity of bacteria among different soil types. The bacterial diversity index of alluvial soil, brown calcic soil, chestnut soil, and sierozem were higher than that of other types of soil. Furthermore, the manner of soil utilization also affected the diversity of bacteria. The Shannon index and richness of cultivated land were the highest and that of unused soil were the lowest. The correlation analysis between bacterial diversity and soil fertility parameters showed that there was no significant correlation between them. The dominant populations of bacteria in soil in the western region of Inner Mongolia include Proteobacteria, Bacteroidetes, Firmicutes, Actinobacteria Acinetobacter, Acidobacteria, Gemmatimonadetes, and Nitrospira. This study can provide a scientific basis for the management and restoration of soil ecosystem and the development and utilization of microbial resources and agricultural production guidance in this region. 参考文献 相似文献 引证文献

Impacts of climate change on net primary productivity of grasslands in Inner Mongolia

Net primary productivity (NPP) of grasslands is a key variable for characterising carbon cycles in grassland ecosystems. The prediction of NPP in Inner Mongolia is important for adaptation to future climate change, food security and sustainable use of the grassland resources. The output from two models, potentially suitable for simulating NPP in response to climate change, was tested against observed aboveground forage mass of dry matter at eight sites in Inner Mongolia from 1995 to 2005. The Classification Indices-Based Model (CIBM) showed an acceptable agreement with field measurements. The impact of climate change on the NPP of grasslands was subsequently analysed by CIBM using future climate projections from a Global Circulation Model based on three greenhouse gas emission scenarios: A2 (medium-high emission), A1B (medium emission) and B2 (medium-low emission) differing in assumptions about patterns of global social and economic development. Generally, significant increases in NPP, compared with the baseline NPP of 3.6 tonnes ha–1 for 1961–90, were predicted. The magnitude of the increase in NPP depended on the emission scenario, as well as on the time frame and region considered. Overall the predicted NPP stimulation increased with the level of emissions assumed, being 4.8 tonnes ha–1 in the A2 scenario, 4.3 tonnes ha–1 in the B2 scenario and 4.5 tonnes ha–1 in the A1B scenario in the 2080s (2071–2100). The increase in NPP in response to climate change differed between regions and there was an interaction with emission scenario. For the A2 and the B2 emission scenarios, the western region of Inner Mongolia was predicted to exhibit the strongest NPP increases, but, under the A1B scenario for the 2050s, the south-eastern region exhibited the greatest increase in NPP. It is concluded that the productivity of grassland in Inner Mongolia is likely to increase in response to climate change but these predicted effects are sensitive to emission scenarios and differ regionally. This will provide opportunities but also challenges for herders and policy makers in adapting to this change.

Aeolian salts in Gobi deserts of the western region of Inner Mongolia: Gone with the dust aerosols

Gobi deserts of the western region of Inner Mongolia are potential dust source area and a dominant source of soluble salts that are transported into eastern Asia and the western Pacific. Currently, the salt species, their emission magnitudes, and their spatial trends in this source area are poorly understood. In the present study, we used intact surface samples and wind tunnel experiments, combined with salt and particle size data, to estimate the spatial trends of ionic species and the contents of terrestrial-derived soluble salts in this region. The salt contents in the surface materials range between 0.28 and 14.78‰ (by mass). However, the salt contents in materials transported by the wind ranged between 1.55 and 16.95‰. In this region, the soluble salts in the PM50 and PM10 fractions ranging between 0.008 and 0.913‰ and between 0.004 and 0.583‰, respectively, with SO42− and Ca2+ contents far higher than those observed in previous studies in East Asia and the western Pacific. Areas with the highest salt emissions were located in the western Ala Shan Plateau and in southwestern Mongolia, and the contents decreased moving towards the southeastern Ala Shan Plateau. In addition, wind tunnel experiments showed that under wind velocities ranging from 8 to 22m/s, the soluble salts ranged between 0.64 and 8.49%, with a mean of 3.45%. Given the significance of western Inner Mongolia for global dust emissions, the emissions of terrestrial-derived soluble salts from these areas should be carefully evaluated in future dust aerosol studies.
