高邮湖地处淮河下游,是淮河入江水道的重要通道,担负着滞洪、泄洪的重要任务,是典型的过水性湖泊。随着淮河流域水利工程的完善,水位常年保持在较高水平,而且汛期上游来水迅速,下游排水却比较缓慢,水位增长快,洪水滞留时间长。这些特点在2003、2004、2005年连续三年充分体现出 Located in the lower reaches of the Huaihe River, Gaoyou Lake is an important channel for the Huaihe River into the river, and plays an important role in flood detention and flood discharge. It is a typical over-water lake. With the improvement of water conservancy projects in the Huaihe River Basin, the water level has been maintained at a relatively high level all the year round. In addition, the incoming water in the upper reaches of the flood season is very rapid, the drainage in the lower reaches is relatively slow, the water level increases rapidly and the floods stay for a long time. These characteristics in 2003, 2004 and 2005 for three consecutive years fully demonstrated
