生态护坡技术在河流环境综合治理中的应用实践

Abstract

河流生态系统在流域生态环境中承担着重要的功能，河流的功能定位与结构分析是确定河流环境综合整治和生态修复方案的首要前提条件。针对目前河流环境综合整治的形势，探讨了国内外河流生态护坡技术要点及工程的主要形式，分析了传统护坡的局限性。在华南地区开展了河流生态护坡技术因地制宜集成应用实践，并初步分析了生态护坡对河流生态环境和景观的影响，其改善河流生态环境及景观的效果较好，建设与维护成本较低、施工简单。将生态护坡技术综合应用于城镇河流环境综合整治具有明显的社会效益和环境效益。 River ecosystems do play a dramatically significant role in the ecological environment of watershed. Functional location and structural analysis of the rivers are the prerequisite for the comprehensive remediation and ecological restoration of river environment. In view of the current situation that comprehensive remediation is going to be implemented on the river environment, the main technical points and the main forms of the river ecological revetments at home and abroad were discussed, and the limitations of the conventional slope protection were analyzed. The application of ecological revetment technology integrated with local conditions has been carried out in the South China region, and the effects of ecological slope protection on the river ecological environment and landscape have been analyzed initially. The impact of ecological environment and landscape enhancing is evidently fabulous; the cost of construction and maintenance is relatively low, as well as construction process can be performed readily. The comprehensive application of ecological revetment in urban river environment has manifest social and environmental benefits.
