Construction method of imitated natural river channel and floodplain wetland
The invention provides a construction method of a simulated natural river channel and floodplain wetland, which comprises the following steps: S1, constructing a simulated natural river channel and a three-level floodplain in a riverbed according to historical daily average flow statistical characteristics to adapt to river channel flow characteristics under different rainfall scenes; and S2, constructing floodplain wetlands with different characteristics according to the selected floodplain type. The ecological service function of the river channel is comprehensively improved by relying on the floodplain wetland; service functions of landscape, soil conservation, wind prevention, sand fixation and the like are realized in a non-rainfall scene; in a rainfall scene, the service functions of reducing non-point source pollution, stagnating and storing flood water, improving water environment quality and the like are mainly played.
本发明提供了一种仿自然河道及河漫滩湿地的构建方法，包括如下步骤：S1：根据历史日均流量统计特征，在河床内构建仿自然河道及三级漫滩，适应于不同降雨情景下的河道流量特征；S2：根据选择的河漫滩类型，构建特征各异的河漫滩湿地。本发明依托河漫滩湿地综合提升河道生态服务功能；在非降雨情景，实现景观、土壤保持、防风固沙等服务功能；在降雨情景，主要发挥削减面源污染、滞蓄洪水、改善水环境质量等服务功能。
