宜兴洑西河生态河道建设工程水土保持措施分析评价

Analysis and evaluation of water and soil conservation measures for ecological river construction project of Fuxi River in Yixing

以宜兴洑西河为研究对象,采用现场踏勘、座谈和无人机航拍等方法对河道断面形式、水土保持工程措施和植物措施进行分析,总结出洑西河东省庄水库以上河段位于竹海国家风景名胜区内,生态环境良好;东省庄水库至油车水库河段以养老、健康和旅游为主;油车水库至永红涧河段处于湖洑镇城区范围内,以供居民娱乐、休闲和游览为主。河道整体上存在岸坡耕种、植物配置单一、河道淤积及富营养化现象,从而针对性提出丰富植物配置、定期清淤河道和加强后期抚育管护等建议与对策,以期为生态河道建设中水土保持措施管理和维护提供建议与指导。

Taking the Fuxi River in Yixing as the research object,the river section form,water and soil conservation engineering measures and vegetation measures were analyzed by means of field survey,discussion and aerial photography of unmanned aerial vehicles.It was concluded that the river section above the Dongshengzhuang Reservoir of the Fuxi River is located in the Zhuhai National Scenic Spot and has a good ecological environment;The river section from Dongshenzhuang Reservoir to Youche Reservoir mainly focuses on elderly care,health and tourism;The section from Youche Reservoir to Yonghongjian River is located in the urban area of Hufu Town mainly for residents’entertainment,leisure and sightseeing.On the whole,there are bank slope cultivation,single plant configuration,river channel sedimentation and eutrophication phenomena in the river course.Therefore,suggestions and countermeasures are put forward to enrich plant configuration,regularly clear the river course and strengthen the later care and management,so as to provide suggestions and guidance for the management and maintenance of water and soil conservation measures in the construction of ecological river course.
