A Study On Design Strategy Of Floodplain Wetland Park In Built Environment

Floodplain wetland is a landscape belt with wetland characteristics on both sides of the river.It has high ecological value and social value.However,with the continuous progress of the urbanization process,a large number of floodplain wetlands built in the environment have been artificially invaded and transformed,causing great damage to the wetland ecosystem.In the construction of floodplain wetland park in the process of ecological protection,the research on its wetland body is often neglected,and the man-made transformation is carried out directly,which leads to the further deterioration of the wetland ecosystem.How to deeply understand the river floodplain wetland,through the rational design techniques,to coordinate the relationship between the wetland protection,the use of the park and the urban flood control,is the focus of the research on the design strategy of the river beach wetland park.This paper takes the floodplain wetland as the research object,and analyzes the two aspects of waterfront ecology and spatial form.Based on the analysis of the components of waterfront ecology and the comparison with other wetland types,the ecological characteristics of floodplain wetland are analyzed in depth.From the three dimensions of horizontal,vertical and vertical,the spatial configuration of floodplain wetland is discussed,and the spatial form characteristics of floodplain wetland are summed up.Based on the influence of built environment on the ecological components and spatial structure of the floodplain wetland,the changes of its ecological characteristics and spatial characteristics were summarized.Based on the theory of ecological restoration and multi natural river construction,the corresponding design strategies are put forward from two angles of ecology and space.The restoration of three dimensional continuous water conditions,the restoration of diversified landforms,the construction of dynamic wetland vegetation pattern and the construction of natural habitats help to restore the ecological function of the wetland.The optimization of the wetland landscape space is promoted through the coordination of the periodic water level change,the horizontal extension of the park area,the defect of the horizontal and vertical space and the inheritance and display of the cultural memory.Finally,taking the "green road and silver beach" project in Qianshan County of Anhui Province as the actual case,it has a deeper understanding of the river beach wetland park design,and puts forward the research prospect from the angle of interdisciplinary research,development and environment friendly water conservancy project.
