根据辽河干流水资源开发利用中的问题,考虑水利工程对天然水文情势造成的干扰,从河流系统整体出发,提出了辽河干流及其直流主要水利工程的生态调度应采取的措施与方案,建立了多水库生态调度多目标数学模型.该模型综合考虑经济效益、社会效益和生态环境效益,在尽量不影响经济效益、社会效益的前提下缩小水文改变度,使水库下游尽量保持天然径流情势,逐步恢复河流生态系统. According to the problems in the development and utilization of Liaohe river water resources and considering the disturbance caused by water conservancy project to the natural hydrological situation, this paper puts forward the measures and schemes for ecological dispatch of Liaohe river and its main DC water conservancy projects from the whole river system, Multi-reservoir ecological scheduling multi-objective mathematical model.This model reduces the degree of hydrological alteration under the premise of not affecting the economic benefits and social benefits as far as possible, considering the economic benefits, social benefits and ecological environmental benefits, so as to keep the natural runoff in the lower reaches of the reservoir as far as possible Restore river ecosystem.
