With the development of the urbanization,many rivers in our country suffer from pollution and destruction of the original ecological function. Changli River, an important river which is located in Guangli town, Dinghu district, Zhaoqing city,also faces the problem of pollution and plays a decisive role in the construction of ecological civilization of Zhaoqing. Therefore,through the analysis of Changli River water quality pollution and ecological damage situation, the current research progress of ecological restoration technology at home and abroad was summarized,as well as the analysis of the characteristics of physical and chemical remediation and ecological technology,came to a conclusion that ecological restoration can effectively control river pollution and restore river ecological function, which provided the reference value for the following harness Changli River.%随着城市化的发展,国内很多河流遭受污染,破坏原有的生态功能.位于肇庆市鼎湖区广利镇的重要河流长利涌同样面临着污染的问题,长利涌的治理在肇庆生态文明建设中起着决定性的作用.因此,本文通过分析长利涌水质污染与生态破坏的现状,综述目前化学和生态修复技术国内外的研究进展,以及分析化学、物理修复以及生态技术的特点和应用,总结出先采用化学处理再用生态修复可以有效治理河流污染与恢复河流生态功能的结论,为后续开展的长利涌治理提供有价值的参考.
