[Objective] The Ten Tributaries Area in Inner Mongolia belongs to the sandy and coarse sediment area and the ecologically fragile area in the middle and upper reaches of the Yellow River. A field investigation was conducted on soil erosion at Xiliugou watershed (a typical watershed in the Ten Tributaries area), and the characteristics and causes of soil and water loss in the watershed were analyzed in order to provide a basis for soil erosion control in the Ten Tributaries Area. [Methods] From September 19 to 26, 2022, and from June 21 to 26, 2023, 15 investigation sites and 14 watersheds were respectively set up along the X640 Jiechai (Jiejiaying—Chaijiapu) line and G109 Jingla (Beijing—Lhasa) line to investigate the vegetation, soil, soil erosion characteristics, and water and soil conservation measures of the investigation sites and watersheds. [Results] Grassland erosion in the watershed was observed to be severe, while erosion of cultivated land was not severe. Wind erosion of bare soil was more serious
