摘要
本文在分析阎王鼻子水库建设前后下游水文情势变化的基础上,根据河道内生态不同需求和不同计算方法,确定水库下游河道基本生态流量和目标生态流量两种需求方案。在充分考虑大凌河流域河道外需水的前提下,研究分析了阎王鼻子水库最大程度满足河道内不同生态需水要求时的调度方案,对改善水库下游河道环境具有一定的指导意义。
Based on the analysis of the changes of downstream hydrological situation before and after the construction of Yanwangbizi Reservoir,according to the different ecological needs in the river and different calculation methods,this paper determines two demand schemes such as:basic ecological flow and target ecological flow.On the premise of fully considering the external water demand in the Daling River basin,this paper studies and analyzes the operation scheme of Yanwangbizi Reservoir when it meets the different ecological water demand requirements in the river to the greatest extent,which has certain guiding significance for improving the downstream river environment of the reservoir.
