长江三峡工程蓄水后，水流和输沙的改变会引起长江中下游河床的变化。本文采用了长江安徽段5个测次的1∶10000长程水道地形图和大通水文站历年的流量、泥沙资料，通过对比分析可以看出：三峡建成后，上游来沙减少，清水下泄导致了长江中下游安徽段河道发生了异常的冲刷和淤积，引起局部河势发生了较大变化。基于成因，对长江中下游干流河道安徽段存在的主要问题进行了阐述和分析，并对中下游干流河道的治理对策与措施进行了探讨。

The Yangtze River after impoundment of the Three Gorges project , water flow and sediment change will cause the riverbed change .This paper adopts the Yangtze River Anhui section 5 measurement times 1/million long-range channel topographic map and Datong hydrometric station over the flow and sediment data , through comparative analysis can be seen:the Three Gorges is completed , the upstream sediment reduction , water discharging resulted in middle and lower reaches of Yangtze River Anhui river had abnormal scour and silting , caused by local regime has greatly changed .Based on the cause of formation , on the main stream of the Yangtze River in Anhui section of the river main existing problems were discussed and analyzed , and on the middle and lower reaches of river course management countermeasure and measure are discussed .
