竞争性用水河流生态流量确定方法研究.

Taking competitive water use rivers as research objects, in view of the current major ecological and environmental problems, with the goal of basin ecological protection and high quality development, an ecological flow indicator system with different levels of habitat target needs was built. By analyzing the dynamic response of representative species to hydrological conditions, using a specific historical period as the reference system for the best state of the river and comprehensive use of habitat model and ecological flow component analysis method, an ecological flow determination method for competitive water-using rivers was established and a case study was carried out by taking the section of Yiluo River into the Yellow River as an example. The satisfaction degree of ecological flow under multi-year average conditions is greater than 85%, the determined ecological flow target of the Yellow River inlet of Yiluo River is reasonable and feasible. The ecological flow determined by this method can better coordinate the balanced play of river natural ecological function and social service function. [ABSTRACT FROM AUTHOR]
