Research On The Spatial Development And Planning Of Cities In Underdeveloped Areas Of Central China

Since the reform and opening up,driven by the regional development strategy,China's eastern,central and western regions have achieved great economic development achievements,but regional differences have gradually widened.With the convening of the Third United Nations Conference on Housing and Sustainable Development and the 19 th National Congress of the People's Republic of China,the focus on fairness and quality and coordinated regional development have increasingly become the main voice of the new era.As an important means of regional development,regional planning,the system and means at the level of national governance,has experienced the background development of political and economic system reform and urbanization,and has formed regional planning practices that are adapted to different stage characteristics and different levels.With the reform of national land spatial planning,it has had a revolutionary impact on regional planning.Whether regional planning can effectively guide the economic development of underdeveloped regions,and how its spatial utility results have become a difficulty in regional development research.As a smaller basic unit in regional development and regional planning,the city area is an important scale in regional research.This article takes Ganzhou City,Jiangxi Province,the underdeveloped city in central China as the research object,based on the regional development theory and related theoretical thoughts,systematically summarizes regional development theory and regional development(mainly refers to the city space as the regional unit,using regional planning as a tool A series of institutional arrangements and measures)and the development results under the institutional arrangements(mainly referring to the spatial structure of the city)to establish a theoretical analysis framework to clarify the four development stages of Ganzhou,and factors such as location factors,natural resources,and systems have always played an important role.The functional elements of each period are different,and the urban space development presents different modes and has stage characteristics.As a tool for realizing regional development goals and resource allocation,regionalplanning has become the most important institutional arrangement in the spatial development process of Ganzhou City.This article reviews two important applications of the regional development theory in Ganzhou: "Ganzhou Urban System Planning(2006-2020)" based on the point-axis system theory and "Ganzhou Urban Area Master Planning(2012-2030)based on the urban area theory year)".Analysis of the evolution of the spatial pattern of Ganzhou City under the arrangement of the two major planning systems and the actual development process,combined with the urban system,population mobility,urbanization,construction land and other aspects of the study,found that the center of Ganzhou is polarized,but the first degree In the decline,showing a more flat trend.The construction land is mainly expanded rapidly along the main transportation cities.Compared with the planning goals,the construction results of Ganzhou's central urban area and Longnan's secondary center are remarkable.The urbanization rate has increased rapidly.The axial distribution of population movement and the outflow trend have slowed down.The clustering effect of the north-south axis is more significant than that of the east-west axis.In order to explain the differences between the institutional arrangement and the actual formation of the city 's spatial pattern,this article establishes an explanatory framework from face to point,explaining the differences from the regional development mechanism and the difference generation mechanism.The study found that the difference between planning and current situation is multi-sourced.Administrative forces led the construction of the central urban area of Ganzhou,and marketization and global economic integration have promoted industrial transfer,industrial diffusion,and knowledge spillovers from developed coastal regions to Ganzhou.Nankang and Longnan gained opportunities for industrial development through the Beijing-Kowloon axis,joined the global division of labor,and improved their population agglomeration capabilities.Anyuan relied on agricultural modernization + Internet to achieve economic poverty alleviation and population return.Finally,a reflection on the theory and practice of regional development is formed.The point-axis system theory has the characteristics of stage and space,and has certain limitations under the open system.In the information age and high-speed rail era,the role of agglomeration and diffusion seems to be too limited to static factors such as space,region,and infrastructure,and is limited to a certain scale.The metropolitan area theory is suitable for the purpose of individual county andstrengthening the overall planning of the city.In the context of the reform of land and space planning,regional planning should become an important collaborative platform for different development subjects to seek maximum development,coordinate interests and regional cooperation,and achieve regional development goals and structural allocation of resources.Provide a development framework for national land spatial planning,coordinate urban-rural systems,value human-land relations,and guide rigid constraints with a global strategic vision.The main innovation of this article is to build a unified theoretical framework that connects the related theories of regional development,regional development practice,and spatial results of regional development.Under the guidance of the theory of regional development,the formulation and realization of regional development goals are different,mainly reflected by the spatial pattern of the city,and the general mechanism and long-term trajectory of regional development can be studied through the planning system and the actual spatial development results.It discusses the applicability and limitations of the regional development theory in what period and under what circumstances,and further improves the regional development theory,and contributes to the reform of the regional planning and development theory in the context of the reform of land and space planning in China.
