近40年来太湖汛情的变化与防洪对策
吴浩云
水利部太湖流域管理局, 上海 200434
摘要:
太湖位于太湖流域中央, 对汛情起着控制作用.通过分析近40年来太湖流域梅雨期、太湖水位、环太湖进出水量的时空分布, 得出梅雨决定太湖主汛期, 东太湖泄洪能力降低、围湖减少蓄水、淤滩影响泄洪, 太浦河、望虞河通而不畅的现实是太湖汛期水位居高不下的重要原因提出预降太湖水位, 加快工程建设, 加强工程管理是太湖安全渡汛的主要措施。

Abstract:
Taihu Lake is one of the five Iargest fresh 1akes.Located at the center of Taihu Lake Basin and controls the flood situation of Taihu Basin The main flood period of Taihu Lake and Basin is determined by plum rain period, which normally starts on June ll and ends on July 20.After an-alyzing the plum rain period in history, the highest water level of Taihu Lake in heavier flooding years, inflow and outflow around Taihu Lake in the past 22 years.the flod situation of Taihu Lake has changed, which is influenced by precipitation distribution, discharge change, and the operation of main channels such as the Taipu River and the Wangyu River.The decrease of dis-charge of Taihu Lake is primarily resulted from the accretion and reclaimed Land in East Taihu Lake.Studying the operational rule of main channels, dredging the mouths of the Taipu River and the Wangyu River.and reinforcing of the Around Thu Dyke are main measures to control flods of Taihu Lake Basin.
