摘 要：
河流生态系统影响评价是闸坝工程运行管理工作的重要内容之一,本文在综述闸坝工程对河流生态系统的影响效应和闸坝控制型河流生态评价方法的基础上,建议运行闸坝工程的决策者通过采取优化河流生态系统的综合管理、连通河流上下游水系、恢复河岸缓冲带栖息地的适宜性、精确估算河流生态需水量等措施,最大限度地减轻对河流生态系统造成的负效应,不断提升河流生态系统的水体净化能力,最终达到满足流域生态文明建设中功能需求的目标。

摘 要：
River ecosystem impact assessment is one of the important contents of dam project and management. Based on the review of the impact effect of dam project on river ecosystem and dam control type river ecosystem assessment methods, this paper suggests that the decision makers of dam management should optimize the comprehensive management of river ecosystem, connect the upstream and downstream river systems, restore the suitability of riparian buffer zone habitat, accurately estimate the river ecological water demand and other measures, minimize the negative effect on river ecosystem, continuously improve the water purification capacity of river ecosystem, and finally meet the functional requirements in the river basin ecological civilization construction.
