摘要

As the most rapidly developing urban agglomeration in China, Yangtze River Delta (YRD) is gradually transitioning toward sustainable development. However, excessive urban expansion threatens food and ecological security, leading to severe land use conflicts (LUCs). Therefore, the government has introduced land control policies to achieve sustainable use of land resources. Considering that policy factors can guide land use behavior, this study innovatively integrated LUCs with control policies. We used land use suitability evaluation to identify LUCs and constructed a comprehensive influencing factor system of LUCs including policy factors. We incorporated spatial correlation factors into the classical regression model to quantitatively explore the driving mechanism of LUCs. The results indicated that in 2020, the total area of LUCs in YRD was approximately 299,800 km²(accounting for 84.07%), with the most intense conflicts concentrated in the northeastern plains. The spatial distribution of conflicts was the result of the combined effects of multiple factors. The strongest positive influence was attributed to average patch area of cultivated land (regression coefficient = 0.3023), while the most substantial negative impact came from DEM (regression coefficient = -0.3660). The economic incentive policies had opposite effects on LUCs (regression coefficient of farmland fertility protection subsidies > 0, while regression coefficient of ecological protection subsidies < 0). Moreover, the influence intensity of different variables exhibited notable spatial heterogeneity. This study addressed the shortcomings of previous research that overlooked policy factors. We aimed to accurately identify LUCs, explain their underlying mechanisms, and propose feasible zoning policies to achieve the goal of land sustainable use.
