今年太湖流域降雨量低于1954年,但水位却超过了1954年,而且水位长时期居高不下。分析其原因,一是太湖水面大量被围垦,达20万亩,调蓄能力减少,二是原有排水通道被大量堵塞,规划中的新排水通道如望虞河、太浦河均未开通。今年太湖流域的特大洪涝灾害,是对我们过去不合理治水的一次惩罚。认真总结过去几十年治理太湖的经验教训,今后必须认真贯彻已经拟订的分散排水的方案:一、江苏境内的望虞河是太湖通向长江的排水通道,它全长60公里,太湖涨水时,可向 This year’s rainfall in the Taihu Lake Basin was lower than in 1954, but the water level surpassed that of 1954, and the water level remained high for a long period of time. Analysis of the reasons, first, a large number of Taihu Lake was reclaimed land, up to 200000 acres, reducing storage capacity, and second, the original drainage channel was a large number of blockages, the planned new drainage channels such as Wang Yu, Taipu River are not open. The catastrophic floods in the Taihu Lake Basin this year are a punishment for the irrational flood control in the past. We must conscientiously sum up the experiences and lessons learned in the past few decades in harnessing the Taihu Lake. In the future, we must conscientiously implement the decentralized drainage plan that has been drafted: 1. The Wangyu River in Jiangsu Province is a drainage channel leading to the Yangtze River. It is 60 kilometers in length, When can be
