Study On Ecological Planning Model Of Residential Areas In Southern Cities Based On Functional Wetland Theory

In recent years,the state has begun to vigorously promote the construction of “sponge city” and “double repair of cities”.In the past,the planning concept of heavy material space in urban residential areas and neglect of ecological environment is urgently needed to be reversed.In particular,for southern cities,wetlands are rich in resources and are closely related to the lives of urban residents.If the urban development and construction can be coordinated with the wetland ecological environment,it will not only alleviate the problems of urban floods and water shortages,but also effectively promote the harmonious construction of human settlements.In this context,based on “functional wetlands” and related theories,methods and practices,based on the wetland ecological protection,the wetland system is included in the planning of residential areas,and new ideas and models for the planning and construction of residential areas in southern cities are proposed..The research results of this paper are as follows:(1)Through the analysis of the types and characteristics of wetlands in southern cities,the distribution of southern cities and wetlands,and the analysis of three aspects of wetland characteristics in residential areas in southern cities,the paper summarizes and extracts “coastal”,“along the river” and “along the lake”."Three types of residential areas.(2)At the macro level,the study on the coupling of the planning structure of the southern urban residential areas with the wetland structure of “coastal type”,“along the river type” and “along the lake type”,firstly,the roads,landscapes and public facilities of the residential area Analyze the status quo combined with wetlands.Secondly,from the construction of wetland ecosystem in residential area,the ecological construction of residential area road and wetland,the ecological construction of residential area landscape and wetland,the study of residential area public facilities system and wetland coupling ecological construction.(3)At the meso level,the study on the functional integration of the three types of residential areas and wetlands of “coastal type”,“along the river type” and “along the lake type” mainly includes the integration of functions of wetland and residential areas,wetlands and residential areas.Functional integration,integration of wetland and residential landscape environment functions.(4)Combining the macro and mesoscopic levels,respectively propose the ecological planning model of coastal-type residential areas and wetlands in southern cities,the ecological planning model along the river-type residential areas and wetlands,and the ecological planning along the lake-type residential areas and wetlands.mode.
