城镇河流生态修复技术研究及应用

Research and Application of the Method of Ecological Restoration on Urban River

河流生态修复是一种快速恢复河流生态环境的技术措施。目前河流生态修复多以水质改善为主,技术尚不完善,缺乏立体化、多指标的技术体系与可推广、可复制的生态修复模式。研究一种集“外源污染防控—内源污染抑制—水生态调控—强化水体净化”为一体的河流水生态修复技术体系,并通过对马田排洪渠生态修复前后河流生态环境状况的对比分析,分析该技术应用效果,可为城市河流生态修复技术研究与应用提供参考。

River ecological restoration is a technical measure for rapidly rebuilding river ecological environment. Socially, river ecological restoration research mainly focuses on water quality improvement, and the ecological restoration technology is not perfect. A kind of three-dimensional, multi-index and can be extended technology system is very needed. A kind of river ecological restoration technology system,which includes external pollution reducing and internal polluton controlling, water ecological regulaiton,water purificaiton strenthen was studied. The application effcet of this multi-technology method on Matian flood river was stduied by comparing the health assessment results of river ecosystem before and after the river ecological restoration construciton was done. The result is helpful to realize and applicae the river ecological restoration on the urban river.
