Primary Research on Ecological Water Demand in Source Rivers for the First Phase West Line South-to-North Water Diversion Project
The field of ecological water demand has been one of the research foci of geographical sciences in the world. The calculation of ecological water demand in source rivers of the first phase western line south- to-north water diversion project is the base of water transfer scale argumentation. Based on the theory research, we considered the need of keeping river system health and protecting the plants of side banks and the living things in river reaches according to the unique eco-environment of western route in source region and the goal of environment protection. Then we selected many methods to calculate the ecological water demand in river reaches. The results stated that the ecological water demand range of various dam is Reba (27.06～40.68m3/s), Aan (3.8～7.41m3/s), Renda (2.87～6.11m3/s), Zhuanda (4.53～7.94m3/s), Huona (4.25～6.73m3/s), Keke (1.75～2.90m3/s). The ecological water demand of vegetation out of river reaches is satisfied by precipitation.
