中文摘要：

经济社会的快速发展不可避免的对河流生态系统造成了损伤,如何使受损河流生态系统恢复到健康状态已经成为当前亟待解决的重要环境问题之一.河流修复生态功能分区是对河流进行适应性生态修复的必要前提和基础,可为制定生态修复目标提供科学依据.本研究在已有分区体系基础上,依据生态功能分区的理论,对河流修复生态功能分区的内涵进行了辨析,从理论上对分区方法进行了探讨,并以永定河（北京段）为例进行了实证研究,提出了永定河（北京段）河流修复生态功能分区方案,最终结果划分6个区域;并结合区域社会经济发展状况和相关发展规划等因素,提出各区段的生态修复调控指标,为永定河（北京段）生态修复提供科学指导.

英文摘要：

Rapid socio-economic development would inevitably result in the damage of the river ecosystem at present and how to restore damaged river ecosystems to health status has become one of the important environmental issues urgent to be solved.Function zoning is the prerequisite for adaptive restoration,which could provide the scientific basis for the ecological restoration goal.In this work,function zoning of river was firstly compared with the main ecological regionalization,for both advantages and shortcomings.Based on the theories of ecological function regionalization,the conception of river restoration and eco-regionalization was discussed and the approach of eco-regionalization was studied theoretically.The Yongding River（Beijing segment） was selected as a study case and ecological function zoning including six river reaches was developed.The regulation index for ecological restoration of each reach was also proposed,which focused on ecological restoration of Yongding river in Beijing.
