Spatial Analysis of Cultivated Land Productivity, Site Condition and Cultivated Land Health at County Scale

Abstract: Cultivated land is a fundamental factor related to the social stability and sustainable development of the whole country. However, the safety of quantity and quality of cultivated land has decreased year by year, resulting in great challenges to the sustainable development of cultivated land. Cultivated land productivity, site conditions, and soil health jointly determine the sustainable development potential of cultivated land. Analyzing and calculating the coupling and cooperative relationship between these … Show more

“…Among them, arable land serves as the foundation of agricultural production, playing a vital role in ensuring food security and the supply of agricultural products. Sufficient arable land can support agricultural expansion and development, providing ample land for farmers to cultivate [78]. However, global arable land resources face challenges such as continual reduction, degradation, and urbanization.…”

“…Particularly, the excessive application and intensive use of chemical fertilizers have had a substantial effect on the health of the cultivated land system. The resulting risks of shallow tillage strata, apparent reduction of organic matter in surface soil, and excessive heavy metals in soil not only exacerbate the deterioration of the ecological environment of cultivated land, but also reduce grain yield, resulting in a decline in the quality and biodiversity of agricultural products and even endangering human health [ 27 ]. At present, the study on the ecological environment of cultivated land resources in the two lake plains mainly focuses on the agricultural ecological security [ 65 ], soil environmental quality [ 66 , 67 ], ecological security of farmland resources [ 68 , 69 ], ecosystem supply balance [ 50 , 70 ], and so on.…”

“…To reasonably assess the health of a cultivated land system, identify the causal relationship between system elements, analyze the operation mechanism between different indicators, and explore the causal chain between natural ecological elements and socio-economic elements, this paper proposes to build a cultivated land system health diagnosis model ( Figure 1 ) combining the PSR (Pressure-State-Response) model and the VOR (Vigor-Organization-Resilience) model on the basis of the research on the indicator system of cultivated land system health evaluation at home and abroad [ 31 , 32 ]. The system of cultivated land is a complicated one that is controlled by humans and is not an unadulterated part of the natural environment [ 27 ]. The evaluation of the health status of the cultivated land system needs to comprehensively screen the ecological, environmental, social, economic, and other attribute indicators related to the cultivated land from the meso and macro scales [ 25 , 30 ].…”
