鄱阳湖不同时期冲淤变化分析

Analysis of scouring and deposition change with different periods in Poyang Lake

本文根据五河控制站泥沙特征变化和湖口站出湖泥沙特征变化情况,分析了出入湖泥沙年际、年内变化规律,同时采用典型断面法,依据1998年长江水利委员会鄱阳湖测量成果以及2010年鄱阳湖基础地理测量成果分析了鄱阳湖不同区域的冲淤变化情况,探求了鄱阳湖区的冲淤分布情况.

This article analyzed the interannual, annual variation law of sediment out or into Poyang Lake,according to the characteristics of the sediment change of five rivers＇ control hydrology stations and Hukou hydrology station. It also analyzed the silt alteration situation in different areas in Poyang Lake based on the result of measurement of Poyang Lake under the Yangtze River Commission in 1998 as well as the geographical measurement of Poyang Lake in 2010. By the typical cross section method, this article also explored the distribution of the sediment scouring and deposition in Poyang Lake Region.
