Evaluation of Agricultural Non-point Source Pollution Infiltration on Clogging and Nitrogen Leaching Effects in BRCs with Different Plants in Dryland Areas.

As high-standard farmland rapidly expands, agricultural non-point source pollution has emerged as a main environmental issue in China. To tackle nitrogen pollution, green infrastructure (GI), especially bioretention cells (BRCs), has been extensively adopted. However, the long-term effectiveness of these systems may be hindered by clogging and nitrogen leaching. In this study, we designed three BRCs simulation devices to investigate the effects of different plants on the removal of TSS TN and NO3-N from runoff through simulated pollutant infiltration experiments. To address this issue, laboratory research has explored the contributions of woody plants like Buxus and herbaceous plants such as Ophiopogon in BRCs, concentrating on their impact on system clogging and nitrogen leaching. The results indicated that, although the total suspended solids (TSS) removal rates in the Buxus and Ophiopogon treatment groups were slightly lower than in the control group, permeability experienced a notable enhancement, with the Buxus group showing a 24.47% increase in permeability. The removal rates of TN and NO3-N in the Buxus group were significantly reduced, decreasing by 31.82% and 41.25%, respectively, in comparison to the control group. After five months, Ophiopogon demonstrated considerably better root growth, with its root length, volume, and surface area all significantly exceeding those of the Buxus group. The choice of plants significantly influenced nitrogen cycling and system clogging, with the reduced removal rates in the Buxus group potentially linked to its weaker root system, lower abundance of actinomycetes, and reduced soil enzyme activity.

How Does High-Standard Farmland Construction Affect Agroecological Efficiency—From the Perspective of Factor Endowment

Based on the factor endowment theory and the agriculture-induced technological innovation theory, this study examines the impact of high-standard farmland construction (HFC) on agricultural ecological efficiency (AEE) and sustainable agricultural development. Using empirical data from 30 provinces in China between 2005 and 2022, it explores how high-standard farmland construction techniques can enhance AEE, considering factor endowment preferences and geographical characteristics. Empirical research indicates that high-standard farmland significantly enhances AEE, particularly in the eastern region, the main grain-producing areas, and the regions with less geographical fluctuation. Additionally, agricultural innovations, capital accumulation, and land circulation reinforce the benefits of such construction, whereas labor mobility has a moderating effect. Quantile regression analyses show that the impact of HFC on AEE initially increases and then diminishes, potentially due to inadequate post-management and maintenance. Consequently, the study recommends that the government enhance policy support and supervision for high-standard farmland projects, integrate agricultural technology with capital accumulation, optimize human resource allocation, guide labor mobility, and reform land transfer systems to boost AEE and sustainability.

Spatial zoning and effect evaluation of county high-standard farmland siting delineation for sustainable cultivated land use in China: A case study in Dali, Shaanxi

High-standard farmland construction is critical for sustainable land use and food security in China. Currently, scientific siting delineation for high-standard farmland at the county level is lacking. Delineation through evaluation and zoning is essential to improve land productivity. This study focuses on Dali County in Shaanxi Province, Fenwei Plain. It analyzes cultivated land changes using the land use transfer matrix and the PLUS. By integrating macro “township-parcel-grid” and micro “farmer” perspective, it establishes a comprehensive evaluation system for high-standard farmland delineation. We delineate construction zones and evaluate potential effect of high-standard farmland. The results reveal that: (1) From 2000 to 2020, the cultivated land area generally decreased. The permanent basic farmland positively contributes to the increase of cultivated land. Land use simulation in 2030 results show that the urgency for land consolidation. (2) The delineated high-standard farmland area in Dali is 85,081 hm2, with comprehensive evaluation index values ranging from 0.2229 to 0.5970, indicating that Dali has the potential for continuous construction of high-standard farmland. (3) This study zones high-standard farmland construction according to the difficulty and time sequence. Delineated high-standard farmland can play potential effect of agglomeration and demonstration, sustainable and coordinated development and grain production capacity increasing. We offer a scientific method for delineating zones of high-standard farmland within county, providing recommendations for sustainable high-standard farmland construction. It serves as a reference for the gradual conversion of all permanent basic farmland to high-standard farmland in China.

The Impacts of High-Standard Farmland Construction on Cultivated Land Improvement in China

The construction of high-standard farmland has emerged as a prominent strategy to increase the total arable land area and augment cultivated land quality. This paper endeavors to scrutinize the policy impacts of this measure on elevating cultivated land quality and increasing land area in China. We employ an instrumental variable model with two-way fixed effects to quantitatively analyze the impact of the construction of high-standard farmland on the area and quality of cultivated land, based on panel data from 30 sample provinces in China from 2009 to 2018. Our results indicate that for every additional 10,000 hectares of high-standard farmland construction, the cultivated land area per person increased by 0.004 hectares, and the overall quality improved by 0.004 grade. The mechanism analysis further shows that constructing high-standard farmland indirectly alleviates cultivated land quality by reducing farmers’ use of chemical fertilizers, plastic film, and pesticides. The results imply that the ongoing construction of high-standard farmland remains a pivotal element in ensuring the sustainable utilization of cultivated land resources and achieving food security and agricultural modernization goals in China.

The Effect of High-Standard Farmland Construction Policy on Grain Harvest Losses in China

The United Nations included reducing harvest losses as a Sustainable Development Goal in 2015, sparking heightened research and policymaker interest in reducing losses to ensure food security. High-standard farmland construction plays a crucial role in ensuring food security. Few studies have combined high-standard farmland construction with grain harvest losses. Drawing on the data from the 2022 Chinese Post-Harvest Loss Survey (CPHLS 2022), the study utilizes OLS (ordinary least square) and quantile regression models to explore the impact of high-standard farmland construction on grain harvest losses. Empirical results show that high-standard farmland construction can significantly reduce grain harvest losses. The research conclusions are still valid after passing a series of robustness tests. The heterogeneity analysis shows that high-standard farmland construction significantly impacts on grain harvest losses for farmers in major grain-producing areas, plain areas, and eastern regions. Mechanism analysis reveals that high-standard farmland construction mainly reduces grain harvest losses by expanding operational scale and enhancing mechanization application. Based on research findings, the Chinese government should formulate a targeted high-standard farmland construction policy, optimize the agricultural machinery operating environment, and promote appropriate operational scale to ensure national food security.

Optimization of the Coupling between Water and Energy Consumption in a Smart Integrated Photovoltaic Pumping Station System

Agricultural irrigation requires significant consumption of freshwater resources and energy. The integration of photovoltaic power generation into irrigation systems has been extensively investigated in order to save the cost of energy. However, current research often neglects the coupling relationship between photovoltaic power generation and irrigation schemes. This study presented a novel smart integrated photovoltaic pump station system to effectively address the issue associated with water and energy consumption in irrigation. An optimization model was proposed to synchronize the energy consumption of irrigation pump stations with photovoltaic power generation, accurately meeting the irrigation water demand while maximizing solar energy utilization. The optimization model incorporates power balance, grid-connected power, and total water demand as constraints while considering pump speed as the decision variable and aiming to minimize daily operational costs. Finally, a high-standard farmland was used as a case study to validate the efficacy of the optimization strategy through two photovoltaic grid-connected policies—one allowing for the sale of surplus power and the other prohibiting it. An improved dynamic programming method was employed to solve for optimal energy consumption schemes under different water demand conditions; the results were compared against traditional methods, revealing potential cost savings ranging from 6.2% to 30.5%. The optimization model and method propose a new operational concept for the irrigation system with photovoltaic generation, effectively utilizing the distinctive features of both irrigation and photovoltaics to optimize water and energy resources.

The Impact of High-Standard Farmland Construction Policies on the Carbon Emissions from Agricultural Land Use (CEALU)

Agricultural activities are the second largest source of greenhouse gas emissions, and carbon emissions from agricultural land use (CEALU) have become a hot issue across the world. Although there are some studies on the impact of high-standard farmland construction policies on carbon emissions, they focus on quantitative analysis and do not give sufficient consideration to the relationship between HSFC and CEALU. Therefore, in this study, by relying on provincial panel data of China for the period 2005–2017, the effect of the high-standard basic farmland construction policy on carbon emissions from agricultural land use per unit area and its regional differences were quantitatively analyzed using the difference-in-difference (DID) model. The results showed that: (1) China’s CEALU per unit area presented a fluctuating upward change, but the growth rate slowed down during the period 2005–2017, from 392.58 kg/ha to 457.72 kg/ha, with an average annual growth rate of 1.31%; (2) the high-standard farmland construction (HSFC) policy led a significant carbon emission reduction effect in agricultural land use and reduced the CEALU per unit area by 10.80% on average. With the promotion of this policy, its carbon emission reduction effect in agricultural land use presented an overall increasing change; (3) the carbon emission reduction effect of the high-standard farmland construction policy in agricultural land use was significant in central China, but non-significant in eastern China and western China.

Bibliometric analysis of China's high standard farmland construction research based on CNKI

Carrying out the construction of high-standard farmland is an important way to implement the principle of "storing grain in the land and storing grain in the technology", and it is an important practice to implement General Secretary Xi Jinping's principle of food security. The construction of high-standard farmland can speed up the modernization of agriculture, help urbanization development, and realize the efficient use of arable land, scientific management, and guarantee the increase of farmers' incomes. The construction of high-standard farmland is beneficial to the country and the people. Using CNKI database publication year, institutions, authors, publications, journals, cited frequency, keywords and other elements, we systematically sorted out the overview of the research field of high-standard farmland construction in China from 1996 to 2024, and comprehensively analyzed the research dynamics and hotspots in this field. The results show that: at present, China's high standard farmland construction research mainly focuses on the theoretical policy, implementation effect and engineering technology; the organization with the most publications in this field is the newspaper, and the two documents with the highest total citation frequency are Research on the Construction Standards and Models of High-standard Farmland in Chongqing Municipality and Construction Standards of High-standard Farmland, respectively, and Comprehensive Agricultural Development of China is the periodical that publishes the most related documents; in the future, the research hotspots will gradually tend to be zoning construction and high standard farmland construction. The research hotspot gradually tends to zoning construction, ecological construction and other aspects, need to accelerate the research of scientific research institutions on this aspect of the research and key technology integration.

Spatial and temporal variation and convergence in the efficiency of high-standard farmland construction: Evidence in China

To assess the efficiency of high-standard farmland construction (HSFC), this study utilized data spanning from 1998 to 2020 obtained from 30 provinces, autonomous regions, and municipalities in China. This assessment was conducted using a three-stage super-efficient slack-based measure data envelopment analysis(SBM-DEA)model. Furthermore, we investigated the spatial and temporal variances and convergence of HSFC efficiency using the Dagum Gini coefficient and convergence analysis. The results firstly show that from 2007 to 2020, China's HSFC efficiency displayed fluctuations and declines, significantly influenced by environmental and stochastic factors. Secondly, it showed that the gap in China's HSFC efficiency has widened, with super-variable density being demonstrated as the primary source of spatial imbalance in HSFC efficiency. Thirdly, it showed that the deviation in the efficiency of HSFC in the central region of China from the average level has shown a gradually declining trend, while the deviation in the efficiency of HSFC in the national, western, eastern, and northeastern regions has not presented a downward trend. Fourthly, it demonstrated that over time, the efficiency of building high-standard agriculture throughout the nation and its four main areas will converge to the same level.

The multiple effects of farmland infrastructure investment on agrifood systems in China—an interdisciplinary model analysis

PurposeAs one of its major strategies, China has made a new plan to further expand High Standard Farmland (HSF) to all permanent basic farmland (80% of total farmland) for grain security over the next decade. Yet, what will be the impact of farmland infrastructure investment on agrifood systems? The paper aims to systematically evaluate the multiple effects (food security, economy, nutrition and environment) of expanding HSF construction under the context of the “Big Food vision” using an interdisciplinary model.Design/methodology/approachAn interdisciplinary model – AgriFood Systems Model, which links the China CGE model to diet and carbon emission modules, is applied to assess the multiple effects of HSF construction on agrifood systems, such as food security and economic development, residents’ diet quality and carbon emissions. Several policy scenarios are designed to capture these effects of the past HSF investment based on counterfactual analysis and compare the effects of HSF future investment at the national level under the conditions of different land use policies – restricting to grain crops or allowing diversification (like vegetables, and fruit).FindingsThe investments in HSF offer a promising solution for addressing the challenges of food and nutrition security, economic development and environmental sustainability. Without HSF construction, grain production and self-sufficiency would decline significantly, while the agricultural and agrifood systems’ GDP would decrease. The future investment in the HSF construction will further increase both grain production and GDP, improve dietary quality and reduce carbon emissions. Compared with the policy of limiting HSF to planting grains, diversified planting can provide a more profitable economic return, improve dietary quality and reduce carbon emissions.Originality/valueThis study contributes to better informing the impact of land infrastructure expanding investment on the agrifood systems from multiple dimensions based on an interdisciplinary model. We suggest that the government consider applying diversified planting in the future HSF investment to meet nutritional and health demands, increase household income and reduce carbon emissions.

In this context, this paper discusses the concept, connotation and objectives of high-standard farmland construction through the literature method and combined with years of experience in high-standard farmland construction engineering technology, summarizes the technical points of high-standard farmland construction, and looks forward to the development trend of high-standard farmland construction technology in China in the future, in order to provide methods and references for China's high-standard farmland construction.

The Impacts and Spatial Characteristics of High-Standard Farmland Construction on Agricultural Carbon Productivity

Agricultural carbon productivity combines the dual attributes of reducing carbon emissions and stabilizing economic growth, and is a core aspect of the new era of low-carbon agricultural development. The construction of high-standard farmland is an important initiative to promote high-yield and high-efficiency agriculture, as well as environmentally sustainable development through land improvement in China. However, the impact of high-standard farmland construction on agricultural carbon productivity and its mechanisms is still in the process of being determined. In order to fill this gap, this study aims to construct a theoretical, analytical framework for the impact of high-standard farmland construction on agricultural carbon productivity. Based on the current situation of high-standard farmland construction and the characteristics of agricultural carbon productivity in China, this study used the panel data of 31 provinces, from 2003 to 2017 in China, to empirically examine the effects, mediating paths, and spatial characteristics of the construction of high-standard farmland on agricultural carbon productivity using a double fixed-effects regression model, a mediating-effects model, and a spatial econometric model. The results show that: (1) High-standard farmland construction has a positive effect on agricultural carbon productivity, with a direct effect coefficient of 0.139 after adding a series of control variables. (2) Furthermore, heterogeneity analysis shows that the impact of high-standard farmland construction on agricultural carbon productivity will vary greatly depending on the topographic characteristics of the studied area, the level of economic development, and whether it is a main grain-producing area. (3) Mechanism analysis shows that agricultural scale operation, agricultural planting structure, and agricultural technology progress all have partial mediating roles in the impact of high-standard farmland construction on agricultural carbon productivity, with mediating effect coefficients of 0.025, 0.024, and 0.013, respectively. (4) Agricultural carbon productivity has a spatial correlation, and for every 1% increase in the level of high-standard farmland construction, agricultural carbon productivity increases by 0.117%, with a direct effect of 0.074% and a spatial spillover effect of 0.043%. Our study explains the impact effects, mechanisms, and spatial spillover effects of high-standard farmland construction on agricultural carbon productivity from theoretical and empirical perspectives, thus deepening the literature on the relationship between high-standard farmland construction and agricultural carbon productivity, and providing a theoretical basis and practical references for improving agricultural carbon productivity from the perspective of high-standard farmland construction policy.

Evolutionary game analysis of government, businesses, and consumers in high-standard farmland low-carbon construction

Abstract Soil is an important carbon reservoir, and high-standard farmland construction projects have significant potential to promote low-carbon development. In order to study the management and implementation of low-carbon production in high-standard farmland construction projects, the tripartite evolution game model of government, business, and consumer is constructed based on the tripartite bounded rationality. Then, the behavior strategy of tripartite stakeholders is analyzed with the method of system dynamics. Finally, the evolution process of tripartite interaction behavior is simulated using the MATLAB tool. The results show that: (1) The subsidy and punishment mechanism of the government must be aligned. In addition, the net income of government regulation is higher than the sum of the government’s environmental governance fees and fines of non-regulation; (2) The government, business, and consumers all choose their own behavioral strategies based on their own interests. (3) When the government’s environmental governance fee reaches a particular value, the system will appear imbalanced. In light of this, it is suggested that the government should increase support for business and use media publicity, consumer subsidies, and other measures to promote the consumption of low-carbon products. The business should constantly reduce the cost of carbon emission reduction through technological innovation.

Soil Nutrient Analysis of High Standard Farmland Construction in Fengxiang Area

In order to ensure China's grain output and food security, we should upgrade the grade of farmland, increase farmers' income, and realize the storage of grain in the land and the storage of grain in technology. While promoting the planning tasks of high-standard farmland construction projects issued by the state and Shaanxi Province, through the determination of soil nutrient indicators in the proposed high-standard farmland area in Fengxiang District, it is pointed out that the average content of soil organic matter in the study area was 12.18 g/kg, which was relatively insufficient as a whole; the average content of soil available nitrogen was 149.45 mg/kg, which was relatively abundant as a whole; the average content of soil available phosphorus was 8.94 mg/kg, which was also relatively insufficient as a whole; and the average content of soil available potassium was 124.82 mg/kg. The whole is moderate. To sum up, after appropriately increasing the content of organic matter and phosphorus, the newly built high-standard farmland can meet the demand for soil nutrients for food crop growth and meet the requirements of high-standard farmland construction in Northwest China.

The important role of intelligent water conservancy in the construction of high-standard farmland

Farmlandis the basis of food production,and also the key and difficult point of agricultural development in China.At present, China’s farmland is generally characterized by small scale, scattered distribution, weak infrastructure, and low level of informatization. High-standard farmland construction is an important policy formulated at the national level to ensure food security and promote agricultural transformation and upgrading. It is based on farmland water conservancy and combines information technology and communication technology with high-standard farmland construction, realizing the whole process of information perception, transmission, and management from field to market. However, China’s farmland water conservancy has problems such as backward irrigation conditions and technology, imperfect supervision and management mechanism, and lack of information professionals. The contradiction between agricultural modernization and high-quality development and insufficient demand for farmland water conservancy has gradually become prominent. Therefore, it is necessary to strengthen the construction of smart water conservancy, and strengthen the use of Internet of Things, cloud computing, big data, artificial intelligence, and other technologies to achieve information sharing and data sharing of high-standard farmland construction, to realize the efficient, accurate, and scientific management of high-standard farmland, and to ensure China’s food security.
