| As the regulator of the urban ecological environment and the carrier of leisure and recreational activities,green space plays an important role in many aspects such as ecology,society and economy.With the development of society,people’s demand for high-quality and healthy living environment and rich and diverse outdoor recreational space is increasing.Urban green space is restricted by the scale of land use,single habitat,and high-intensity human activities,which cannot satisfy residents well.Demand.Located in the urban fringe area outside the concentrated urban construction area,there are many types of non-construction land,such as woodland grassland,pit pond wetland,ditch reservoir,etc.The distribution is fragmented but the total amount is huge,and it has great potential to supplement the comprehensive service function of urban green space.Screen the land that is related to the urban functional space and the ecological green space system for integration and utilization,which can not only meet the leisure and recreation needs of the citizens,but also protect the green ecological landscape resources of "mountains,forests,fields,lakes and grasses",and prevent the decline and decline of the internal habitat of the urban fringe Inefficient use of resources has a positive effect.Based on this,in view of the diversification,dynamic utilization and uncertainty of non-construction land,the article puts forward the concept of informal green space,and strives to explore the adaptation of mountain cities without changing the original land functions of relevant non-construction land.The optimization of the ecological green space system in the fringe area and the utilization method and path of the expansion of the value of non-construction land in the fringe area are expected to provide more green leisure activities for urban and rural residents,and form a rich and characteristic mountain city ecology,greening and landscape system.Compared with plain cities,mountain cities have undulating terrain.The types and scales of non-construction land that constitute informal green spaces in the fringe areas are more complex and changeable,the ecological environment is more fragile,the natural environment resources are more abundant,and the green landscape is more distinctive.Research on green space has greater value.Therefore,this paper selects informal green space in the fringe area of mountain cities as the main research object.First,based on qualitative analysis and quantitative screening,we identify the key use areas of informal green space,and then explore adapting to the characteristics of mountain city fringe areas to match the external use demands and internal use possibilities.In view of the above-mentioned ideas,the 7 chapters of the article are divided into four parts,and relevant discussions are carried out.The first part is the introduction to Chapter 1.It analyzes the research background,clarifies the related research concepts and spatial scope of informal green space,and focuses on informal green space in mountainous urban fringe areas,and further elaborates the research purpose and significance,as well as research methods And frame and other content.The second part is Chapters 2-3.Firstly,it summarizes related theories,literature reviews,and similar practice cases at home and abroad;then,it discusses the land use and spatial characteristics of informal green spaces,related land use types,comprehensive value and service function attributes,and A detailed study of the main problems and predicaments currently faced was carried out,based on which the utilization ideas and planning guidance were proposed,and the Yongchuan District of Chongqing City and the Mindong New District of Meishan City,Sichuan Province were clearly used as the main reference actual cases for this research and demonstration.The third part is Chapter 4-6,which is the core part of this article.A detailed research and discussion on the selection,utilization and management of informal green space has been carried out.Chapters 4-5 first identify key areas of informal green space through qualitative analysis of important factors affecting the use of informal green space and quantitative screening based on GIS technology in multiple ways.On this basis,it focuses on the research and discussion on the ideas,methods and paths of the use of "informal green space" in urban fringe areas.Based on the overall utilization concept of ecological background,landscape paving,and function superposition,through the integration and utilization of informal green spaces and related spaces,and the utilization of composite service functions,three levels of informal green spaces of "node-corridor-network" are established.The relationship with the ecological space and the urban construction space makes it integrated into it and becomes an important component,giving play to its ecological greening and landscape value;through "fusion+ repair","support + connection","penetration + integration" Use paths to implement active protection and utilization of key areas of informal green space;through the ecological greening network,connect and integrate scattered informal green spaces to realize the comprehensive protection and utilization of related areas of informal green space.On this basis,through the measurement of the supply-demand relationship and compatibility,it is clear that the diversified service functions based on the ecological service function,the economic service function and the social service function are combined and parallel,fully stimulate the value potential of the relevant land,and provide considerable output to the city The value of diversified comprehensive services.Chapter 6 proposes targeted land use management and control methods and measures based on the characteristics and core planning content of informal green spaces in mountainous urban fringe areas.The fourth part is Chapter 7,which summarizes the main conclusions and innovations of the research,and puts forward the shortcomings of this research. |
