摘　　要：永定河面临着水资源短缺、河道断流、水污染加剧、水生态系统严重退化等生态环境问题,极大地影响了其发挥河流生态服务价值,制约了沿岸地区社会经济发展。本文根据"千年生态系统评估报告",提出了不同功能类型河流生态服务价值评估方法,对不同生态修复目标的永定河生态服务价值及生态修复效果进行定量评价,可为生态修复技术方案优化和水资源配置提供科学依据。Faced with the problems from the eco-environment,such as shortage of water resources,river cutoff,aggravation of water pollution,serious degradation of water ecosystem,etc.,the realization of the ecosystem service value of Yongdinghe River is greatly impacted,and then the socio-economic development along the river is largely restricted as well. In accordance with the the＂Millennium Ecosystem Assessment Report＂,the methods for assessing the ecosystem service values of the river with various kinds of functions are proposed herein,and then the quantitive assessments on the ecosystem service values and eco-restoration effects of Yongdinghe River for various eco-restoration objectives are made; which can provide the scientific basis for the optimization of the technical scheme for the eco-restoration and the allocation of the water resources concerned.
