汾河中游闸坝区枯水年环境流量调控研究

Study on regulation and control of environmental flow in the middle reaches at gate dam area of Fenhe River during dry year

本文以汾河中游闸坝区为研究对象,从闸坝群联合调控和环境流量目标入手,在研究区最小环境流量计算的基础上,以满足最小环境流量为目标,设置5种不同工况对闸坝区枯水年天然来水进行调度计算。并根据计算结果提出3种建议方案,确定其优先顺序,通过合理的闸坝调度,缓解建坝对河道生态环境产生的影响,充分发挥闸坝工程的效益。

Gate dam area in the middle reaches of Fenhe River is adopted as the research object in the paper.It starts with the perspective combining gate dam group joint regulation and environmental flow target.Five different working conditions are set for scheduling and computing natural water during dry year in the gate dam area on the basis of minimum environmental flow computing in the study area in order to meet the minimum environmental flows as the goal.3 proposals are proposed according to the calculation results.The priority sequence is determined.The influence of dam construction on river ecological environment is alleviated through rational gate dam scheduling,thereby fully exerting the effect of gate dam project.
