This paper deals with the process of sediment production by erosion and sever-ity of its damages in Huangfuchuan watershed. Also,this paper analysed the effects ofTianchao hydraulic power station in Fugu upon the sedimentation of the downstreamriver bed in this watershed, and the effects of Huangfuchuan watershed upon Tianchaohydraulic power station and sediment deposition of each river section of trunkstreamsof the Yellow River in Fugu. At the same time, the authors analysed the sedimentproduction by erosion, and causes of intensified soil erosion, and further pointed outthat land reclamation by human beings is the important cause to intensify soil ero-sion. Also. less rainfall with more rainstorms and strong weathering special bedrocksare the main links in the strongly-eroded areas in the middle reaches of the Yellow-River.Therefore,conserving the existing loess, increasing grass and shrub coverage, andstrengthening protection engineering structures in gullies can be the fundamentalmeasures at present-for comprehensive control over Huangfuchuan watershed.
