Abstract ［Objective］ The investigation of temporal and spatial variations in soil erosion and its influencing factors in Yunlong County is of great significance for the advancement of featured agriculture, management and restoration of ecological environment, and soil erosion control in alpine and canyon regions. ［Methods］ The GIS and RUSLE model were employed to simulate the spatiotemporal evolution characteristics of soil erosion in Yunlong County from 2000 to 2020. The relationship between featured agriculture and soil erosion was analyzed. By considering influential factors such as elevation, slope, annual average rainfall, vegetation coverage, and land use type, the quantitative attribution of soil erosion was examined using a geographic probe model. ［Results］ 1) From 2000 to 2020, the average erosion modulus in Yunlong County exhibited a decreasing trend across five stages (each stage included five years), being 1 644, 1 085, 878, 661 and 467 t/(km2·a), respectively, and the overall soil erosion shifted from mod
