太湖上游的水文特征及灾害分析

Analysis on Hydrological Characteristics and Disasters in the Upper Area of Taihu Lake

分析了1957～1988年太湖上游主要入湖河道的水位和流量变化规律及其与降水量的关系。基于年径流量,对太湖上游河流每年的丰枯等级进行了评价,讨论了太湖流域的洪涝灾害特征,提出了可根据本文所分析结果进行太湖洪涝灾害预测的结论。

The water level, runoff and precipitation during period from 1957 to 1988 in the inflow area of Taihu Lake and the correlations among them are analyzed. Based on annual runoff, the levels of high and low water in the upper rivers of Taihu Lake in each year are evaluated. The characteristics of flood and waterlogging disasters in the Taihu basin are discussed. All the results of analysis in this paper can be used for flood prediction in the Taihu basin in the future.
