Research On Spatially Structural Evolution Of Xi'an Since 1978 To 2002 During

The integration of marketization,decentralization and globalization since China's reform and opening up has fundamentally changed the power foundation of urban space development and the space configuration patterns,with the urban economy-society-space in a process of combination and transformation.Under such a background,Xi'an,with more than 3,100 years of urban development history and more than 1,100 years of history as a capital city,has entered a severe period of urban transformation.Many historical space arrangements cause its space development to go through a complex process of evolution,highlight the particularity of the transformation of urban spatial structure in Xi'an,directly influence the development trend of urban space in Xi'an and have important historical significance during the evolution of urban spatial structure in Xi'an.This paper takes Xi'an urban spatial structure evolution as the object,using the map reduction,methods of system analysis,field investigation,the process of "analysis"-"identification"-"mechanism" is the avenue,analysis of characteristics of Xi'an urban spatial structure evolution stage and dynamic mechanism;Due to the typicality and particularity of reform and opening during Xi'an urban spatial structure evolution,which will provide a scientific basis for the sustainable development,at the same time,provide empirical basis for the research on the similar cities.Around the goal oriented,the research content is divided into four parts:The first part: the related research foundation and theoretical system of urban spatial structure building.To establish the research system of urban spatial structure as the goal,it determines the theoretical basis and technical route.Firstly,it studies the research progress of city from three aspects as domestic-foreign-Xi'an,summed up the revelation;Secondly,it establishs the process of "analysis"-"identification"-"mechanism to explain" research path,and the research system is divided into process mechanism analysis and explain;Finally,on the basis of relevant theories,it constructs "process analysis system" and "mechanism to explain system",respectively.The second part: Spatial development foundation and historical stage of Xi'an city.First of all,it expounds the geographic conditions of urban space development,historical background and development space;Secondly,it illustrates the development of xi 'an urban spatial structure from the system,society,economy,space developing,defining the role and status of the study period;Finally,the spatial structure development since the reform and opening up is divided into two stages including 1978-1992 and 1992-2002.The third part: the characteristics of analytical research on urban spatial structure of Xi'an city.In xi 'an urban spatial structure of the development of the process analysis and characteristic identification for the purpose,relying on the analysis of characteristics of "system" built in this paper,it analyzes urban spatial structure evolution process and its characteristics.First of all,from the pattern of "flat" and "functional type" two level study of urban spatial structure evolution process in stages;Secondly,in the summary of "planar pattern" on the basis of the features and function type ",it refines the evolution of urban spatial structure characteristics through the superposition.The fourth part: the dynamical mechanism of the development of urban spatial structure.To explain the mechanism of urban spatial structure evolution as the core,relying on the paper constructs the "mechanism explanation system","power factor" and "social subject" two aspects,it investigates the evolution of urban spatial structure mechanism.And then it explain the evolution of the two phase coupling mechanism through the "power factor" and "social main body".There are three innovation points in the research process.Firstly,From the perspective of the research object,it expands the time in the research of the development of the urban spatial structure of Xi'an city,contributing to a complete coverage of urban spatial structure research period.It aims to summarize the whole rule of spatial structure of development period,and to study the whole rule of China during the transitional period.It proposes empirical basis for the development of urban spatial structure.Secondly,From the perspective of research method,morphological types and multiple levels of the city history research methods in the introduction to the process of urban spatial structure analysis,and it builds a "flat pattern" and "functional type" two aspects of the process of urban spatial structure analysis system,with the basic logic of historical research,to expand the application field of urban morphology in urban structure research level,the method has a certain innovation.Thirdly,From the perspective of research conclusion,historical sites of Xi'an city in the process of urban spatial expansion,which play a decisive role in the strength of the urban space differentiation,internal restructuring,its influence on the urban space is structured;And marketization,decentralization system since the reform and opening up,economic and other aspects of the adjustment,affecting urban spatial structure are embodied in the "delta" and the function of city of "modernization",with the development of different historic cities and coastal cities.
