Plant Landscape Design Research Based On Wetland Park Function Division

The construction of wetland park is one of the effective ways to protect and utilize wetland resources.With the gradually accelerate of the wetland park construction in recent years,more and more design problems appeared.Plants are important elements of wetland,plant landscape is the basic element of the wetland park planning and design.The article analyzed the advantages and disadvantages of plant landscape in different wetland park functional partitions,and the plant landscape design pattern in different function division of wet land park was proposed.Based on the function division of different types of wetland park,the article explored the characters of different function divisions.Taking the division pattern presented by National Wetland Park Construction,which divides the wetland park into conservation area,function display area,experience area and management services area,as the basic structure,the plant landscape characteristics were particularly analyzed.Representative wetland parks include Hangzhou Xixi national wetland park,Hong Kong wetland park,south sea elk garden and Beijing Cuihu wetland park were chosen as the study area,based on information collection and field investigation,their design characters in different function division were analyzed,and the design bright spots of plant landscape were summarized.The key points of plant landscape design in function division of wetland park were summarized as follows: from the plant natural succession view to recover the wild grow state in conservation area,from the scientificity view to design water quality purification landscape in function display area,from the view interactivity to design arboretum,specified garden and interesting garden in experience area,from the aesthetics view to design the external and internal plant landscape of buildings in management services area.Based on the data result of the wetland park plant landscape preference questionnaire,under the guidance of wetland ecology,garden aesthetics and recreation principles,design guidelines and forms in different function division of wetland park were proposed.In the case design phase,based on the theory and design guidance,combine with the current plant landscape situation of Changziying wetland park,plant landscapes in different function divisions were redesigned.Wetland function exhibition area focus on the display of water purification function,wetland experience area shows the interaction idea between landscape and tourists through wetland arboretum,picking garden and children active area,providing new thoughts for the subsequent wetland plant landscape design and references for the effect play of plant landscape in different function divisions.
