Abstract:: The effects of land use structure on soil loss are very important for territory protection. In order to investigate the influence of land uses on soil erosion over the watershed, RS and GIS techniques were utilized and RUSLE model were selected to acquire the spatial data of the land uses and the soil erosion of the Yunmeng Lake watershed. The results showed that during the period of 1986-2010, soil erosion situation had improved with the soil and water conservation and ecological restoration project, but the soil erosion was still serious with the total annual erosion amounting to 6.3 million tons from 6.47 million tons. In all types of land uses, farmland showed the most serious erosion with high soil erosion modulus 5325 t/(km²·a) and 5504 t/(km²·a), respectively, accounting for 85.8% and 84.7% of total soil erosion. Additionally, the grassland was another main object to be protected with the total proportion of strong, extremely strong and severe erosion zones of 40% and 44%, respectively. As farmland and grassland types in turn, the erosion area of residential land increased from 1010 hm² to 2608 hm², and soil erosion amount increased from 54000 t to 142000 t.
