摘要
选取深圳市大沙河为典型河流,以Tennant法、Qp法、近10 a最枯月平均流量法、年内展布法、湿周法等方法,开展适用于雨源型河流的生态流量研究。结果表明:Tennant法与湿周法对具有一定补水工程设施的雨源型河流的生态流量计算结果最为合理。并针对大沙河生态流量目标提出生态流量管控措施,为雨源型河流生态流量确定及保障工作先行先试,为推进深圳市雨源型河流生态系统健康持续发展奠定基础。
Taking Dasha River in Shenzhen as a typical example,Tennant method,QP method,average flow method of the driest month in recent 10 years,annual distribution method,wet week method and other methods are used to carry out the ecological flow research suitable for rain-source rivers.The results show that the Tennant method and the wetted perimeter method are more reasonable for the calculation of ecological flow in rain-source rivers with certain recharge engineering facilities.The ecological flow control measures are proposed for the ecological flow target of Dasha River,which is a pilot test for the determination and guarantee of ecological flow of rain-source rivers and lays the foundation for promoting the healthy and sustainable development of rain-fed river ecosystem in Shenzhen.
