Study On Ecological Restoration Design Of Urban River Wetland Park

River is the basis of human civilization.As an important part of river ecosystem,river-type wetland has higher productivity and biodiversity because of "edge effect".River wetland has been encroached and destroyed in the process of human economic and social development and urban expansion,and the river environment has deteriorated.Today,with emphasis on the construction of ecological civilization,river ecological construction has been paid more and more attention.Restoring River wetland is an important means to improve the river ecological environment.On the other hand,the construction of wetland parks is the best way to restore and protect urban wetlands,especially river-type wetlands.With regard to the research and development of river wetlands,foreign developed countries began to carry out relevant research and practice in the 1970s,and formulated laws and regulations to promote the natural restoration of river wetlands.In recent years,while strengthening the construction and protection of wetlands,more attention has been paid to the restoration and protection of river wetlands.Eco-restoration is to guide the positive development of ecosystem by means of human intervention,which is of great significance for the sustainable development of urban river wetlands.Based on the theoretical research of river wetland ecological restoration,this paper summarizes the methods and Strategies of river wetland ecological restoration by analyzing relevant theories and practical cases at home and abroad,and explores and applies them to the construction of Urban River Wetland park.Based on the above studies,the strategies of zoning protection,habitat restoration and species restoration are put forward.Taking Panlong Island Wetland Park in Zaozhuang City as the practice object,the ecological restoration landscape design of the damaged river wetland space in Panlong Island is carried out,the healthy relationship between human and river wetland ecosystem is coordinated,and the urban wetland park with both ecological protection benefits and recreational value is built.It is expected to provide design reference for the construction of similar wetland parks.
