Spatial and Temporal Characteristics and Driving Force Analysis of Cropland Change: Taking Dangyang City, Yichang City as Example

With the land use data of Dangyang City, Yichang City, Hubei Province in 2000, 2010, and 2020, 13 factors of nature, economy, and society were selected as the driving factors affecting the change of Cropland by using the land-use transition matrix and the kernel density analysis. In this study, the dynamic degree model of cropland use was introduced, combined with the geographic detector method, to explore the spatiotemporal variation characteristics and main driving factors of cropland in various towns in Dangyang City from 2000 to 2020. The results showed that the distribution of cropland generally showed a decreasing trend from southeast to northwest. From 2010 to 2020, the cropland in Dangyang City changed significantly, and the cropland area decreased. Economic and social factors turn out to be the main factors affecting the distribution of cropland. When interacting with other factors, the impact on cropland is weakened, and natural factors have interactive effects on cropland.
