摘要
从河流中引蓄洪水实现洪水资源化,引水渠首内外水位差是引蓄洪水水量的关键之一。月亮泡水库为嫩江下游的旁测水库,汛期库内外水位总存在一定的差异,并且库外水位低于库内水位的差别不大而出现频率较高。现以月亮泡哈尔金闸为例,通过对库外水位低于库内水位的情况统计和水位差特性分析以及建造泵站效益费用分析,论证了建造泵站引蓄嫩江洪水是必要的并且经济上是可行的,从而在这一工程措施下可以提高嫩江洪水资源化效率,将灾害洪水转化为水资源。
Channeling flood water from rivers to realize flood resource utilization, the water head of inside and outside of channel head is one of keys to flood quantity. The article takes the Ha'erjin Sluice of the Moon Reservoir as example to analyze the expense and benefit of low water head pumping station, and it is proved that the construction of pumping station for channeling the Nenjiang River flood is necessary and feasible, which can alleviate the local water resources pressure.
