Differentiation Characteristics And Spatial Pattern Of Urban Economic Social Vulnerability

Since the 1980 s,our country realizes high-speed economic development,to the first decade of the 21 st century;China's GDP growth has a double-digit rate surged 30 years.Since reform and opening-up,urban economy led China's economy and society to overcome the food and clothing problem,solved due to the shortage of resources and environmental pollution caused by the growth rate of decline and unsustainable problem,in under the guidance of innovation-driven strategy,mineral type resource-exhausted cities and industry behind the development of the city problem will be further easing.Now main difficulties are in front of the urban development,urban population caused by the excessive agglomeration city spread and traffic jams,the change of industrial structure is not in conformity with the cities of the actual state of the economy and cause environmental pollution,demographic dividend gradually disappear,and population structure further deterioration,and so on,the city's economic and social problems become the main problem of urban sustainable development,has evolved into the causes of urban economic and social vulnerability produce.Vulnerability of the 20 th century at the beginning of the 21 st century,frequent internationally on climate change and frontier problems in the study of urban sustainable development,urban economic social vulnerability theory and empirical research and geography about system analysis is an important part of people,is for nature,economy,social coupling system function study of one of the frontier science.This article is based on the fragility of the knowledge,theory and practice of 2334 county-level cities across the country for economic social vulnerability research,the concept and connotation of urban economic social vulnerability analysis,on the basis of through constructing the index system from two aspects of spatial differentiation characteristics and spatial pattern of 2334 county-level cities of the country's economic social vulnerability evaluation.The full text is divided into five chapters.Chapter 1 as an introduction,mainly from the thesis research background and research significance,the thesis research ideas and main contents and innovative points from three aspects are discussed.Among them,the study of urban economic and social vulnerability background,main contents and innovative points are the focus of this chapter.Chapter 2 is theoretical part of the full text,take the construct the theoretical basis of the full text.The main content includes introduction of vulnerability,the urban vulnerability and the concept of urban economic social vulnerability origin and connotation,and domestic and foreign scholars to urban economic social vulnerability and the latest research progress.As an important research thesis,urban economic social vulnerability and has similarities between urban sustainable development.Chapter 3 mainly introduces the article analysis of the index system and model.Through redefining real connotation of "the city",to establish scientific and reasonable index system,and the several important analysis model of this paper.This chapter is the full text of the computing basis,the essential role of the interpretation of the result of the later analysis play an important role of explanation.Chapter 4 is the main part of the article,mainly from two aspects of spatial differentiation characteristics and spatial pattern analysis of calculation results.Characteristics of analysis mainly from the differential,gradient,clustering and hierarchical 4 aspects,space,mainly from the spatial distribution pattern of the global autocorrelation,agglomeration and hot spot analysis and distribution of elliptic four Angle,the former adopts chart description method,the latter is given priority to with map display.Chapter 5 is conclusion and prospect.Then,summarized the main results of handled in the summary,on the basis of the article some of the deficiencies are discussed,and from the availability of the data and try to from a more microscopic perspective into the analysis of the follow-up to the city's economic social vulnerability research put forward its own views and expectations.The innovation of this article lies in the city's economic social vulnerability research deepening,identify and differentiate the concept and connotation of urban economic social vulnerability;From the point of view of theoretical and empirical interpretation of the theory of county-level city as the research object of rationality and practical feasibility.
