Study On The Defects And Optimization Paths Of Urban Spatial Structure In Sichuan Province

The process of modernization is always accompanied by the continuous advancement of urbanization and the continuous improvement of urban structure.Urbanization brings about sustained and healthy economic development and transformation and upgrading of industrial structure,which ultimately leads to coordinated regional development and overall social progress.Since 1978,under the continuous advancement of industrialization,China's urbanization has experienced a development process from a low starting point to a poor foundation to a fast growth rate.In the 40 years since the reform and opening up to 2018,the number of permanent residents in China has increased from the initial 170 million to 830 million.The urbanization rate has increased by 41.66 percentage points from the initial 17.92% to 59.58%,reaching an annual growth rate of 1.042 percentage points.As the three major economic zones with China's economic growth,Beijing-Tianjin-Hebei,Yangtze River Delta and Pearl River Delta have created 36% of GDP with 2.8% of the country's land area and become the leading economic development land in China.As a material carrier of urbanization development,urban space has an important impact on urbanization and the flow of urban factors.First of all,globalization and market integration make the rational allocation of factors in the space.Enterprises and related investment entities will choose the best location to maximize profits.With the changes of production factors,policy environment,market conditions and cultural concepts,Through the accumulation of upstream and downstream industries in cities and towns,urban space with certain scale,function and form is formed.Secondly,the process of promoting urbanization has always been a matter of great concern to the Party Central Committee.The report of the 16 th Party Congress pointed out that “it is necessary to adhere to towns with Chinese characteristics”.The road to the 17 th National Congress of the Communist Party of China put forward the policy guidelines of “promoting the coordinated development of large,medium and small cities and small towns”;the report of the 18 th National Congress of the Communist Party of China emphasized that “urbanization is the source of power for economic development”;It is pointed out that “promoting the coordinated development of small and medium-sized towns and small towns and accelerating the process of urbanization of agricultural transfer population”.Only by focusing on the imbalance between the development of large,medium and small towns and small towns in the urban agglomerations,supplementing the shortcomings and strengthening the weak points can promote the balanced development of the towns.The rational layout of urban space has become a hot topic for the country to pay attention to urban development.Its optimization and adjustment has laid an important foundation for coordinating urban-rural relations,coordinating the development of large,medium and small towns,and improving the quality of new urbanization.This article takes Sichuan as the main body of research.First,Sichuan is an important “Accelerator” for economic development in the western region.Second,Sichuan is the most important ecological barrier in the upper reaches of the Yangtze River.It is an important growth point for the construction of the Chengdu-Chongqing Economic Zone and an important industry in China.agriculture,military,tourism,cultural provinces.Thorough analysis and in-depth study of the basic defects,scientific layout and optimization of Sichuan's urban spatial structure are of great strategic and practical significance for comprehensively promoting Sichuan's regional resource development,economic development,social progress and even the overall upgrading of the new urbanization process in the western region.Based on the spatial development pattern of Sichuan Province in the “One Belt and Five Districts”,this paper attempts to explore the optimal path selection of urban spatial structure in Sichuan Province by analyzing the existing defects of urban spatial structure in Sichuan Province.Based on the three main clues of urban spatial density,scale and shape,the current situation of urban spatial structure in Sichuan Province was explored.Through the analysis of urban spatial structure point elements,line elements,surface elements and spatial industrial structure,the relevant indicators of spatial structure of Sichuan cities were obtained.Evaluation results and main defects;explore and establish the open cooperation based on the promotion of urban-rural integration,focusing on strengthening industrial support,cultivating emerging growth points,supporting the development of urban agglomerations,and rationalizing the network layout.Coordinated new urbanization space development pattern.Firstly,this paper expounds the research background,research significance,research methods and research framework,research innovation and main limitations,main conclusions and research prospects of urban spatial structure in Sichuan Province,and further combs the relevant theories of urban spatial structure.The paper summarizes the literature review at home and abroad.Secondly,it describes its development trend from the development history,development status and development characteristics of urban spatial structure in Sichuan Province,and explores through four aspects: spatial structure point,line,surface and industrial structure.The shortcomings of urban spatial structure in Sichuan Province;Finally,the strategic framework of urban spatial structure with strategic opportunities,strategic objectives,strategic principles,strategic significance and strategic thinking as the main core content is constructed,and the path selection of urban spatial structure optimization in Sichuan Province is explored.Based on the theory of urban spatial structure and the optimization of urban spatial structure in Sichuan,this paper attempts to explore urban spatial density,urban spatial scale,and urban spatial form.The research perspective extends to the urban space of 21 cities and states within Sichuan Province.Structural optimization,through analyzing the existing defects of urban spatial structure in Sichuan Province,finding out the current problems,comprehensively constructing the strategic framework of urban spatial structure in Sichuan Province,Based on the urban agglomeration and the strategic thinking of open cooperation as a guarantee,explore the spatial structure optimization of Sichuan cities with the main content of promoting urban-rural integration,strengthening industrial development support,cultivating emerging growth points,clarifying the development focus of urban agglomerations and rationalizing network layout.Path Selection.
