摘要

After the construction of Dadingzishan Navigation Power Junction on Songhuajiang River,the natural characteristic of the river on Harbin section was changed,forming 160 km backwater reservoir area influenced by the dam.The underwater topographic survey data and hydrological monitoring data are used in the paper,the dynamic influence of the project on hydrological regime and sediment are analyzed.%松花江大顶子山航电枢纽运行后，改变了原松花江哈尔滨段天然河流的属性，受大坝回水的影响形成了长约160 km的库区。文章采用水下地形测量数据及水文监测数据，阐述了工程对水文情势的影响，对泥沙淤积进行了动态分析。
