| 摘 要： | 为掌握三峡水库175 m试验性蓄水过程中库区水位、流量、含沙量变化过程，通过三峡库区寸滩、清溪场、万县、朱沱（三）水文站实测的水位、流量、含沙量、水面比降资料，分析了蓄水过程中三峡库区沿程水面比降、库区水文站的水位流量关系、含沙量变化、库区冲淤变化等。分析结果为认识掌握三峡水库175 m蓄水后库区水文泥沙的变化规律积累了资料，对探索三峡库区水文泥沙的监测方式和分析研究将具有积极作用。

| Abstract: | In order to make clear the variation process of water level,discharge and sediment content during the period of 175 m trial impoundment of TGP reservoir,we applied the measured data of water level,discharge,sediment content,water surface slope at the stations of Cuntan,Qingxichang,Wanxian,Zhutuo(3) to analyze the variation condition of water surface slope,level-discharge relation,variations of sediment content and scouring-silting in the reservoir area.The analysis results are useful for mastering hydrology... |
