Abstract:: Tuanshangou watershed was selected as the study area in this paper. Based on measured data, the 60’s Shejiagou, Tuoerxianggou and the 80’s Chabagou soil erosion amount were calculated by using the RUSLE structure in the meanwhile taking channel erosion into account. The results showed that the sediment yield status is very well consistent with the practical situation of soil erosion in Chabagou watershed. The sediment delivery ratios of Shejiagou in 60’s and Tuoerxianggou were 0.73 and 1.03 respectively. The data of Chabagou in the 1980s was 0.325.
