摘要
结合汉江中下游这类南方河流面临的水资源紧缺与水环境恶化问题,建立了分别基于水文学与水力学的河流生态需水量计算模型,提出了水文-水力学耦合生态需水量计算方法。经汉江中下游河道多个不同河段、不同典型年、河流生态需水量计算研究,得出了该河流分段生态控制流量。本研究为河流生态需水量计算理论的发展,和南水北调中线工程实施后丹江口水库的合理调控以及汉江中下游地区水资源科学管理提供了依据。
Aiming at the problems faced by the middle-lower basin of the Hanjiang River, the features of fiver ecological water requirements in the humid areas are analyzed, and the calculating model is established based on the hydrology and the hydraulics. A new method coupling hydrology and hydraulics is put forward. What＇s more, by calculating the river ecological water demand of the middle-lower basin of the Hanjiang River on different sections, different typical year, different wet and dry seasons , ecological control flows at different sections are obtained. The various ecological water demand calculation methods and their advantages and disadvantages are also compared. At the same time, this paper provides scientific gist for the development of the river water requirements calculation theory of Southern China, for the effective control of the Danjiangkou Reservoir, and for the scientific operation of water resources of the middle and lower reaches of Hanjiang River when South-to-North Water Transfer Project is finished.
