Study On The Spatial Pattern Conservation And Planning Strategy Of Putian Urban Green Heart Based On The Concept Of "City Betterment And Ecological Restoration"

In the process of rapid urbanization,the city's economy,construction and population have developed rapidly,and a series of "urban diseases" have followed.The disorderly spread and expansion of the city has led to the destruction of the urban ecological environment,the lack of traditional features and the decline of urban history and culture.As an important part of urban spatial structure,urban green heart has the function of maintaining urban ecological health,shaping urban characteristics and providing urban green open space.With the increasing severity of “urban disease”,urban green heart has also been affected.The ecological environment is deteriorating,the features are lacking,and land resources are heavily invaded.The protection and planning of urban green heart has been paid more and more attention,and it is urgent to use the new planning ideas in line with the current era as the theoretical guidance.The concept of " City Betterment and Ecological Restoration " is to balance the relationship between urban construction and ecological construction,to build a harmonious symbiosis between ecology and city,to promote urban repair and ecological restoration,and to be a new idea for urban connotation development and governance.Applying the concept of “City Betterment and Ecological Restoration” to the protection and planning of urban green heart,it can effectively solve the problems faced by urban green heart,restore its ecological function and cultural function,and supplement the urban green shared open space to promote urban areas and rural areas.Harmony and symbiosis,building a new pattern of urban-rural integration.Firstly,the thesis defines and explains the research object and related concepts,and proposes research ideas and methods.It also studies the related research at home and abroad and constructs the research framework of this paper.Secondly,through summarizing and summarizing relevant theories,it sorts out the practical cases of urban green heart protection and planning at home and abroad,summarizes its experiences and lessons,and extracts the common problems in urban green heart planning and protection in theory and practice,and analyzes at the same time.The guiding significance of the concept of “City Betterment and Ecological Restoration” for urban green heart protection and planning.Then,through the analysis and research on the characteristics and development opportunities of Putian City Green Heart,based on the field investigation,it analyzes and summarizes the common manifestation of the common problems with other cities' green heart protection and planning,and explores the concept of “City Betterment and Ecological Restoration”.Applicability in the protection and planning of the green space pattern in Putian City.Then,by analyzing the value factors affecting the spatial pattern of urban green space,the paper explores the protection path of urban green space under the concept of “City Betterment and Ecological Restoration”,and constructs the concept of “City Betterment and Ecological Restoration” based on ecological pattern,village pattern and humanistic pattern.The strategy of protecting the green space pattern of Putian urban green heart.Finally,combined with the previous research on the opportunities and problems of urban green development,the paper puts forward the strategy of Putian urban green heart planning based on the concept of “City Betterment and Ecological Restoration” in terms of built environment,regional vitality,social context and management guarantee mechanism.In order to provide reference and reference for the protection and planning of other cities' green hearts.
