城市硬化河道生态修复与管护探析

Ecological recovery and management and protection of hardened river courses in cities

城市硬化河道的形成是由多年河流治理工程偏水利轻生态造成的,周边城市规划与配套已经形成一定格局,河道断面扩宽以及坡度放缓短时间内无法实现。综述了适用于城市硬化河道生态修复的思路,以四川成都市龙泉驿区驿马河生态修复为例,简述了其采取的生态治理理念和方法,并给出了加强河道长效管护的几点体会建议。

Hardened river courses have been formed over the past years as less attention paid on ecology, which has made it difficult to widen the channel section and realize slope slowdown in a short period of time as the plan of neighboring cities and counterpart facilities have been fixed. Theories and methods for ecological recovery of hardened river courses are briefly introduced by using the case of Yima River in Chengdu City of Sichuan Province, together with a number of suggestions for long-term management and protection of the river.
