1997～2001年黄河小浪底水库库区水文泥沙测验资料,采用水文分析的方法,分析施工运用期、蓄水运用初期等不同时期库区各因子站的水流泥沙运动特征、库区泥沙淤积量及其淤积形态和水库初期运用的回水影响等,并着重分析2000年洪水期含沙量变化过程以及库区泥沙淤积上延现象,初步得出库区不同时期的水流泥沙运动基本规律.由于受当时设站规模的限制,库区水文泥沙资料尚存在不足.今后需加强小浪底水库泥沙淤积状况的监测,收集更广泛的库区水流泥沙资料,为制定小浪底水库运行调度方式奠定基础.
Hydrological and sediment test data of the Xiaolangdi Reservoir in the Yellow River from 1997 to 2001 were used to analyze the characteristics of water and sediment movement at various factors in the reservoir area during the construction period and the initial period of water storage. Quantity and sedimentation pattern of the reservoir and backwater effect of the initial reservoir application. In addition, the process of sediment concentration in the flood season in 2000 and the sediment deposition in the reservoir area are emphatically analyzed, and the basic principles of the sediment movement in different periods in the reservoir area are basically obtained Due to the restriction of the size of the station at that time, the hydrological and sediment data in the reservoir area are still inadequate. In the future, it is necessary to strengthen the monitoring of the silt deposition in the Xiaolangdi Reservoir and to collect a wider range of sediment information in the reservoir area. Way to lay the foundation.
