| 摘 要： | 长江三峡工程蓄水运行后，来自长江上游的泥沙滞留于库区，清水下泄，出库泥沙量明显减少，坝下河床受到冲刷，支流湖泊的供沙也将发生变化，使得进入长江中游河段的泥沙有所减少。本文对长江中游干流河段螺山水文站的径流及来水来沙等水文特性影响进行研究，对于该地区乃至下游地区的防洪调度、港口修建、航道整治与维护、滩涂围垦、工农业生产及生态环境保护等，都具有十分重要的指导意义。

| Abstract: | After impoundment and running of Three Gorges project, sediment from the upper rea- ches of Yangtze River resorts in reservoir area. When water discharge, sediment significantly reduces; dam river bed is scoured and sediment supply of tributaries changes, making sediment reduce in middle reaches of Yangtze River. The study on effects of Three Gorges project on hydrological characteristics of Luoshan Station, including runoff, water and sediment inflow, is of great guiding significance to flood control operation, port construction, channel improvement and maintenance, tideland reclamation, industrial and agricultural production and environment protection. |
