维持河流健康的城市河流生态修复策略探讨——基于重庆清水溪调研思考
|
摘要
近些年来,由于城市河流严重受到城市经济过快发展和人口猛增的影响,导致城市河流在其利用和治理的过程中出现了各种问题,使得城市河流生态承受能力下降,自然水生态系统遭到破坏。文章通过对"河流健康""城市河流生态修复"的内涵阐述,基于重庆市清水溪的调研,剖析了其存在的一些问题,同时在调研的基础上,提出了城市河道的自然化改造、城市河流的生态河提护岸等城市河道生态修复策略,以恢复河流的自然功能与状态为目的,从而使得城市与河流和谐相处,实现相互发展。
In recent years, as urban rivers have been seriously affected by the rapid development of urban economy and the rapid increase of population, urban rivers have experienced various problems in the process of utilization and treatment, which has reduced the ecological endurance of urban rivers and natural aquatic ecosystems. been destroyed. Based on the connotation of "health health" and "urban river ecological restoration", this paper analyzes some problems existing in Chongqing Qingshui Creek, and on the basis of research, proposes the natural transformation of urban rivers. The urban river ecological restoration strategy of urban rivers, such as ecological rivers and revetments, aims to restore the river's natural functions and state, so that the city and the river can live in harmony and achieve mutual development.
