海曙区生态活水方案研究

Study on the Scheme of Ecological Water Transfer in Haishu District

针对城市枯水期水环境问题,研究海曙区生态活水方案,建立研究区MIKE11水量水质耦合模型,统筹考虑不同水源与退水闸碶联合调度,拟定生态活水方案,模拟分析不同方案下水环境改善效果。结果表明,海曙区皎口水库按1.74m^3/s规模下泄,高桥泵站和黄家河泵站分别以13.44、1.00m^3/s规模引水,保丰闸、行春碶和屠家堰配合退水,可取得较好的水环境改善效果。研究成果可为类似区域提供借鉴。

Aiming at the water environment problems in the urban dry season,the ecological water transfer schemes of Haishu District was studied.A MIKE 11 hydrodynamic water quality coupling model of the study area had been constructed by considering multiple sources of water diversion and drainage paths joint scheduling.And then a number of ecological water transfer schemes had been formulated so as to study the improvement of different scheduling conditions on water environment in the study area.The results show that the Jiaokou reservoir is discharged at the scale of 1.74 m^3/s,the Gaoqiao pumping station and Huangjiahe pumping station are diverted at the scale of 13.44 m^3/s and 1.00 m^3/s,and the Baofeng sluice gate,Xingchun sluice gate and Tujia weir are opened to discharge water,Haishu district can achieve better water environment improvement effect.The research results can provide a reference for similar regions.
