Abstract: The Pearl River Basin is an ecological barrier for the economic development of the Pearl River Delta, with complex inducements for soil erosion within the basin. Based on the Chinese Soil Loss Equation (CSLE), this article analyzes the changes in soil erosion intensity, area, distribution, and influencing factors in the Pearl River Basin from 2011 to 2023. The results indicate that during this period, the area of soil erosion in the Pearl River Basin has significantly decreased, and the intensity of soil erosion has also notably decreased. From 2011 to 2022, the land use area of forests and construction land has increased, and the vegetation condition has improved. The annual area of comprehensive soil erosion control has generally shown an increasing trend. Through quantitative analysis of the influencing factors of soil erosion changes, this study provides data support and theoretical basis for scientific soil and water conservation.
