摘要
阜阳水系综合治理项目包含颍河凤凰湿地建设,凤凰湿地在颍河边滩布置挺水植物和沉水植物等,形成边滩植被水流的形态。通过由实验室实测数据验证过的边滩双层植被(分别模拟挺水植物、沉水植物)的流速分布解析解,推求颍河凤凰湿地的流速分布。结合流速分布结果,对工程的防冲设计进行验证,为边滩生态湿地项目的设计提供了边滩植被水流计算方法。
Fuyang river system comprehensive control project includes Yinghe River Fenghuang wetland construction,in which emergent plants and submerged plants are arranged at Yinghe riverside beaches,forming the vegetation form of side beach vegetation. According to the analytical solutions for the velocity distribution of the double-layer vegetation at the beach simulating aquatic plants and submerged plants respectively which are verified by lab data,we find out the velocity distribution of the Yinghe river Fenghuang wetland.Combining with the results of velocity distribution,we verify the anti-scour design of the project and provide a method of beach vegetation flow of the ecological wetland design project.
