Design Of Restoration And Recreation Area Of Dongshan Wetland Park In Longyan Based On Resilient Landscape

With the acceleration of urbanization in China,the problem of water pollution is becoming more and more obvious,and the wetland resources in cities are seriously damaged.Urban wetland park is a model of protecting wetland resources,which is on the basis of paying attention to ecological benefits and also has comprehensive functions.As a public open space in a city,the more important role of urban wetland park is to serve as a green lung for the city in order to regulate the microclimate of urban area,regulate and store rainwater and flood,conserve water resources and enrich regional species,besides providing recreational and recreational venues for citizens.The factors restricting urban wetland parks are complex,such as climate,hydrology,human activities and so on.The factors are closely related and interacted,and their changes are uncertain.Fast,static design and single strategy for the design of wetland parks can not meet the uncertainty of change and the characteristics of comprehensive functions for urban wetland parks.This paper systematically summarizes the concept of urban wetland parks and the development status of urban wetland parks at home and abroad,and summarizes the bottlenecks and problems encountered in theconstruction of domestic wetland parks.At the same time,based on the preliminary study of the concept of resilient landscape,this paper draws the necessity of combining the concept of resilient landscape with urban wetland park,and presents a new idea of combining the concept of resilient landscape design with urban wetland park.By studying five typical planning and design cases of river or wetland parks at home and abroad,this paper summarizes the resilient landscape design strategies that can be used for reference.On the basis of theoretical combing and case summary,this paper provides theoretical basis and design method for the planning and design of restoring recreational area of Dongshan Wetland Park in Longyan.Based on the investigation of the current situation in the planning scope of Dongshan Wetland Park Restoration Leisure Area in Longyan City,the hydrological conditions,current landscape,land use and surrounding environment of the site were analyzed,and the existing problems were found.Based on the previous theoretical analysis and site analysis,the design strategy of restoring recreational area of Dongshan Wetland Park in Longyan under the concept of resilient landscape was put forward.Under the guidance of three resilient landscape strategies,ecological purification resilient strategy,water storage and flood detention resilient strategy,and dimensional resilient strategy,the design concept of resilient landscape is integrated into the design.The designregards "water purification" as the key point of realizing the landscape elasticity,restoring the natural vitality of the site,maintaining the stability of the landscape ecosystem and enhancing the ecological elasticity of the landscape.The design should integrate the function of greenway,closely integrate the urban life of citizens,and give full play to the social flexibility of landscape to create a high-quality urban leisure space with rich ecological structure and sustainable development.This paper attempts to combine the concept of resilient landscape with the planning of urban wetland parks,trying to fill in the deficiencies of current related research to a certain extent.While discussing the related theories of wetland ecology,it also provides ideas for the planning and design of urban wetland parks and riverside greenways,and plays a certain reference role for the future construction of urban wetland parks.
