Research On The Evaluation And Optimization Of Production-Living-Ecology Space Of Tourist Towns In Southern Jiangsu From The Perspective Of Resilience Theory

Under the background of new urbanization,small tourist towns have become one of the important types of characteristic small towns in my country.As a pioneering region of the society and economy,southern Jiangsu has a large number of small tourist towns.However,in the process of construction and development,due to the dual effects of internal and external disturbances,the urban system’s self-equilibrium state has been broken.The production-living-ecology space that carry the economic,social,and environmental subsystems have shown certain inadaptability,the quality of various spaces has declined,and different functional spaces have invaded and conflicted with each other.This paper attempts to introduce the theory of resilience,relying on the evaluation of the resilience of the production-living-ecology space,to study the resilience characteristics and current issues of the production-living-ecology space in the tourist towns of southern Jiangsu,and to propose optimization strategies in order to promote the orderly development of productionliving-ecology space,and to better realize the sustainable development of small tourist towns.Firstly,the concept definition and research summary of resilience,small tourist towns and production-living-ecology space,analyze the feasibility of introducing resilience theory into production-living-ecology space in tourist towns,and then interpret the resilience Sansheng space,point out the coordination and cooperation of production-living-ecology space,and jointly decide The resilience level of small tourist towns,and at the same time it is proposed that the resilience characteristics of production-living-ecology space are manifested in three aspects: heterogeneity in form,redundancy in structure and diversified functions.Secondly,based on the resilience characteristics of production-living-ecology space,the analytic hierarchy process is used to construct the production-living-ecology spatial resilience evaluation system of small tourist towns in southern Jiangsu,and three typical small tourist towns in southern Jiangsu are selected as the research samples.Carry out qualitative investigation and analysis of resilience,judge the relative resilience of various spaces,and then carry out in-depth quantitative evaluation based on the evaluation system,comprehensively judge the resilience index and characteristic status of the productionliving-ecology space.The study found that there are certain differences in the resilience level of the production-living-ecology space in tourist towns in southern Jiangsu.The three-life space of tourist towns with different resilience levels presents different characteristics and problems.The low resilience category is characterized by system disorder and disintegration of form and structure;medium resilience category presents spatial resilience differentiation and lack of power for single function;high resilience category It presents the characteristics of the balanced development of the three lives and the level of resilience to be maintained.Finally,for small tourist towns with different levels of resilience,the three-life space optimization strategy is proposed.The low-level resilience category should be reorganized in an orderly manner to improve the spatial morphology and structure level.The integration of the three generations is needed to build a space implementation guarantee mechanism.
