太湖流域汛期河湖等水位线的判读及其应用

Isohath and its application of hydrologic situation during flood seasons in Taihu Basin

在中国湖泊-流域数据库的技术支撑下,绘制出太湖流域20世纪内5次(1931,1954,1983,1991,1999年)梅雨洪水期,不同雨情、水情下的河湖等水位线．以上述系列图幅为基础,解读了水情及水位发展过程,同时初步分析了等水位线在防洪中的应用,以及新出现的太湖流域第三次水势演变等研究结果．

Based on lake-watershed database of china, the hydrologic situation figures of the five plum-floods in the 20 century were drafted out in this paper, i.e. the isohaths in five heavy flood, years（ 1931,1954,1983,1991 and 1999）. The results indicated that isohaths wild be useful in the demonstration of hydrologic situation for flood control in recent years.
