摘要

该文论述了皇甫川流域侵蚀与产沙的过程及其危害的严重性

并分析了府谷天桥电站对该流域下游河床淤积

以及皇甫川流域对天桥电站、黄河干流府谷段泥沙淤积的影响。同时笔者还对该流域主要侵蚀产沙方式

土壤侵蚀加剧的原因进行了分析。指出:人类开垦

是土壤侵蚀加剧的重要原因。降水偏少

且多暴雨及强烈风化的特殊基岩

是该流域成为黄河中游剧烈侵蚀地区的关键所在。因而“保护现存黄土

增加草灌覆盖

加强沟道防护工程”是目前皇甫川流域综合治理的根本措施。

Abstract

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.
