从1998年嫩江特大洪水谈洪水资源利用

Water Resources Conservancy in the View of 98'Big Flood of Nenjiang River

1998年嫩江发生了特大洪水,几百亿立方米洪水横扫松嫩平原过后,则是连续5年干旱,显示出洪水资源利用的重要性.松嫩平原区内有大片无河网的内流区域,湿地发育广泛,这些湿地的蓄水容量相当可观,充分利用湿地对洪水的适应性,可以调节总体水量不足的问题,实现洪水资源化.发挥蓄滞洪区的蓄洪、滞洪双重功能,利用可以控制的洪水,实现防洪和水资源利用的双重效益.适当抬高水库汛期限制水位,拦蓄汛末洪水,增加兴利水量,使嫩江有限的水资源发挥更大的效益.

The 98＇ big Flood in Nenjiang Drainage Basin and the following 5 - year drought show the importance of flood conservancy. There is a vast land of inward marsh with large storage capacity in Songhuajiang and Nenjiang Plain. How to make full use of flood resources to meet the needs of flood storage and flood discharging in Nenjiang Drainage, trying to realize a dual function, that is, flood control and water resources conservancy are suggested.
