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.
