摘要
本研究在收集分析国内外有关生态环境需水研究进展的基础上,紧密结合黄河水环境和水生态特点,界定了黄河生态环境需水量的内涵和组成。对宁蒙(下河沿—头道拐)、龙三(龙门—三门峡)和下游3个重要河段的河道生态需水量、环境需水量计算方法及生态需水量、环境需水量耦合等问题进行了研究,提出了黄河干流10个重要水文断面的适宜生态环境水量和最小生态环境水量。
On the basis of collecting and analyzing the data from the relevant studies on eco-environmental water demand at home and abroad, the connotation and composition of the eco-environmental water demand of the Yellow River are defined firmly based on the characteristics of the Yellow River＇s aquatic environment and ecology, and then the calculation method and the coupling of both the ecological water demand and the environmental water demand of three important reaches, i.e. Ningmeng, Longsan reaches and its lower reach are studied as well; from which the suitable and the minimum eco-environmental water demands for 10 important hydrographic sections of the main stream of the Yellow River are put forward at last.
