为分析辽宁省多沙河流水库建设对水力过渡区生态环境的影响，选取大凌河流域的阎王鼻子水库、白石水库，辽河流域的闹德海水库、石佛寺水库，构建包括水文特征、地貌特征、流态特征、生态环境特征及社会服务功能的评价指标体系，采用模糊综合评价法对水库物理生境完整性进行评价，结果表明：多沙河流水库水力过渡区物理生境完整程度总体处于“一般”状态，水库生态系统遭到一定程度破坏，需采取措施进行恢复和保护。“,”In order to analyze the advantages and disadvantages of the effects of the construction of multiple sandy stream reservoirs in Liaon-ing Province on the ecological environment in the hydraulic transition zone,the paper selected Yanwangbizi Reservoir and Baishi Reservoir in the Daling River basin,Naodehai Reservoir and Shifosi Reservoir of Liaohe River basin to build the evaluation system from five aspects of hydrological characteristic,geomorphic characteristic,flow pattern characteristic,ecological environmental characteristic and social service function. It evaluated the reservoir physical environmental integrity by using fuzzy comprehensive evaluation method. The results show that the physical and economical integrity of hydraulic transition zone in the multiple sandy stream reservoirs is “normal”,the reservoirs′ eco-sys-tem has been destroyed to a certain degree and needs to take measures to restore and protect it.
