摘  要:
选取团山沟为单元沟道小流域,依据实测资料,采用RUSLE模型架构计算坡面侵蚀量的同时,考虑沟道侵蚀,在此基础上对20世纪60年代蛇家沟、驼尔巷沟和80年代岔巴沟土壤侵蚀情况进行计算。结果表明:模拟岔巴沟流域侵蚀情况较好,60年代蛇家沟和驼尔巷沟泥沙输移比分别为0.73和1.03,80年代岔巴沟流域泥沙输移比为0.325。

摘  要:
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.
