Research On Landscape Design Method Of Urban Lakeside Green Corridor Based On Near-natural Concept

Urban lakes are an important part of the urban water environment,with the acceleration of urbanization,the development and utilization of urban lake resources are also continuously strengthened,most of the urban lakeside space has appeared lake water pollution,biodiversity reduction,landscape over-artificial and other ecological environment deterioration problems.As an ecological link between the city and the lake,the urban lakeside green corridor is an important part of the sustainable development of the city.Under the guidance of the concept of near nature,the landscape design of the urban lakeside green corridor aims to return the site to the original natural ecological state and help the healthy development of the city.It uses limited human intervention to carry out near-natural design of the urban lakeside green corridor landscape,restore and protect the natural ecological landscape of the urban lakeside space,enhance the ability of urban lakes to heal and purify themselves,and is conducive to the harmonious development of cities,lakes and people.Taking the concept of near nature as the main theoretical guide,taking the urban lakeside green corridor as the research carrier,and taking ecological restoration as the goal,this paper explores the principles,strategies and techniques of the landscape design of the urban lakeside green corridor based on the concept of near nature,and creates an urban lakeside ecological space integrating water vein,green vein and cultural context.By sorting out the research results and overviews related to the nearnature theory and the urban lakeside green corridor landscape,combing the development context,it is found that there is a lack of research theories and achievements related to the urban lakeside green corridor landscape design,and points out the necessity of near-natural design for the urban lakeside green corridor landscape.Then,the relevant basic theories of landscape design research of urban lakeside green corridors based on the concept of near nature are introduced,and relevant excellent cases are analyzed and learned.On this basis,the structural characteristics,spatial pattern and functional characteristics of the urban lakeside green corridor are analyzed,and the "City of 100 Lakes"-Wuhan City as the research representative,the Google Earth software image map is used to screen the research objects with the landscape characteristics of the urban lakeside green corridor greenway in Wuhan,analyze the current situation of the landscape of the lakeside green corridor in Wuhan,and explore the principles,strategies and techniques of the landscape design of the urban lakeside green corridor based on the concept of near nature,mainly from the macro,meso and micro perspectives.In view of the ecological problems arising from the construction of the lakeside green corridor landscape in Wuhan,this paper proposes the methods of near-natural design of the urban lakeside green corridor landscape: near-natural planning of spatial pattern,strengthening the sustainability of land landscape,restoring the ecological vitality of the water environment,and building an ecological natural barge.Finally,this paper takes "Asia’s largest lake in the city",Wuhan Tangxun Lake,as the design empirical object,and carries out the practice of near-natural design of the lakeside green corridor,further verifies the rationality of the research methods and the application value of the theoretical results,summarizes the main conclusions and innovation points of this paper,and looks forward to the follow-up research.
