Diagnosis of Land Use Potential Conflict Based on DSE Model

Abstract

Diagnosis of potential land use spatial conflicts plays an important role in land use spatial planning and regional spatial control. Taking Daye city as an example, a DSE diagnostic model is established from the three-dimensional perspectives of land adaptability, socio-economic driving force and ecosystem service value. Social-economic driving force is characterized by per capita net income of farmers, population density and night light data. Ecosystem service value is modified by illumination and soil erosion. The results show that the areas of extreme conflict, high conflict and moderate conflict in Daye are 28.43 km2, 137.12 km2 and 595.32 km2, respectively, accounting for 1.82%, 8.75% and 38.01% of the total area; the areas of extreme conflict are mainly distributed around the main urban area of Daye, while the areas of high conflict are widely distributed around the main urban area and town centers. The results accord with the actual situation of Daye
