摘要
为提高中小型河流河道生态修复治理效果,本研究以黄河支流宛川河为研究对象,通过研究中小型河流生态修复技术路线,对项目河道实施疏浚联通、垃圾清理、采砂坑整治、覆土绿化、生态湿地及生态缓冲带建设等生态恢复措施,实现生态流量下泄,清水长流,修复河滨生态缓冲带,增加植被覆盖率,全面恢复河滨缓冲带水源涵养及生态涵养功能,提高生态截污及河流自净功能,减少水土流失及地质灾害,消除生态环境问题及隐患,可为类似项目提供参考。
in order to improve the ecological restoration and control effect of small and medium-sized riv⁃ers,this paper takes the Wanchuan River,a tributary of the Yellow River,as the research object.Through the study of the ecological restoration technical route of small and medium-sized rivers,the ecological restoration measures such as dredging and connecting of the river channel,garbage cleaning,sand pit treatment,soil covered greening,ecological wet land and ecological buffer zone construction are taken to realize the ecological flow discharge,long-term flow of clean water,restoration of the river⁃side ecological buffer zone,and increase the vegetation coverage,Comprehensively restore the water conservation and ecological conservation functions of the riverside buffer zone,improve the ecological pollution interception and river self purification functions,reduce water and soil loss and geological di⁃sasters,and eliminate ecological environmental problems and hidden dangers,which can provide refer⁃ence for similar projects.
