摘　　要：河道作为城市生态系统的重要组成部分,其污染问题受到了普遍关注。近年来,全国掀起了城市河道治理的热潮,一些城市的点源污染已得到控制,黑臭现象基本消除,城市河道面貌初步改观。在点源污染得到控制的基础上,面源污染的控制和生态系统的恢复逐渐成为河流研究的热点和治理城市河道的大趋势。综述了目前国内外主要应用的河道生态修复技术,提出必须结合多种河道修复技术,并且从流域尺度进行河道的生态系统恢复。River is an important part of an urban ecosystem,and its pollution has been concerned universally.In recent years,our country set off a boom of urban river remediation.Since the point-source pollution is under control in some cities,the rivers have not been black and stinking and become better than before.On the basis of controlling the point source pollution,non-point source pollution and ecological restoration are becoming a hot spot of the river research and a big trend of urban river remediation.The article introduces the main domestic and foreign techniques of the river ecological restoration,proposes that it must combine with a variety of river restoration techniques to restore the ecological system of the river at the basin scale.
