水库群与闸坝联合调度对水质的影响评价

Influence evaluation of combining regulation of reservoir group and gate dam on water quality

选取浑河、太子河流域为研究对象,制定水库群与闸坝联合调度方案。基于MIKE11构建了包含可控制水工建筑物的水动力水质模型,并将其应用于调度方案水质响应分析。研究结果表明,在流域尺度内制定水库群与闸坝水量联合调度方案,不仅能够在一定程度上对河流水质改善起到促进作用,还能在流域水资源量较匮乏条件下实现对水资源的合理调配与利用。

Taking Hunhe river and Taizihe river basin as research objects, the combining regulation of reservoir group and gate dam are made out. Based on MIKE11 model, the paper sets up the water hydrodynamic and quality model considering controllable hydraulic structures, which is applied in the water quality response analysis of regulation scheme. The results show the built water quantity combining regulation scheme of reservoir group and gate dam in watershed scale could not only promote the water quality improvement of river to some extent,but also realize rational allocation and utilization of water resources under the condition of the water resources shortage in river basin.
