Research On Evolution Mechanism And Optimization Of Regional Population Space Structure From The Perspective Of Sustainability

The development of economic globalization promoted the acceleratedurbanization process in China. Through the regional development to promote thewhole national economy has been the basic principle of the economic and socialdevelopment in our country. With the rapid promotion of urbanization process,regional population space structure will be in dramatic change and excessivepopulation agglomeration will bring the damage of environment and the waste ofresources, while too small population will be difficult to support the economicdevelopment. How to guide the regional population space structure evolved towardsthe social, economic and environmental sustainability through the effective measurehas become a significant topic for discussion in the regional economy research.Therefore, this paper begins with the study of regional population space structureevolution, thoroughly analyzes the effects and direction of driving factors, regulateand optimize the populatin space structure with scientific methods, and realize thesustainable development of regional population, resources, environment, economyand society. This paper determined the evolution law of regional population spacestructure by theoretical analysis and model construction, established the theoreticalanalysis framework of evolution and optimization and provided the basis andmethod for the sustainable evolution.This paper basicly demarcated three definitions of region, population spacepattern and regional sustainable development and introduced the theoretical basis ofregional population space structure evolution and optimization. Regional populationspace structure has been divided into5stages from time dimension which has beencarried out the qualitative analysis and quantitative interpretation. This paperanalyzed the driving factors of regional population space structure evolution frommacro and micro perspectives respectively, summarized the evolution mechanism,established the concept model of urban population growth and provided methodsand measures for quantizing the main driving forces, function extents and directionsof urban growth.Based on the classic concept model of single-center and multi-center functionof urban population density and Alperovich population density gradient, this paper utilized the relevant methods of spatial autocorrelation to choose the regional centercities, selected related indicators, calculated the urban comprehensive environmentlevel, established the multiple linear regression model between the density gradientand indicators according to the economic, social and environmental factors whichinfluenced the density gradient. Finally, this paper found out the factors whichinfluenced the aggregation and dispersion capacity of central cities and establishedthe modified polycentric regional population density evolution model.This paper defined the meaning of regional population space structureoptimization and analyzed the optimized characteristics. Determined the total goaland principles of the optimization; established the evaluation method model ofregional population space structure from the perspectives of the resourceenvironment, the economic development and the earing capacity of social resources;pointed out the regulation and control function of the government in the regionalpopulation space structure optimization and put forward the specific path of theregional population space structure optimization in three aspects of resourceenvironment, the economic development and the transportation construction.Finally, based on the theoretical analysis framework established in theprevious parts, this paper carried out the empirical research focused on Guangdongprovince and Pearal River Delta region and quantitative validation on drivingmechanism of regional population space structure evolution, polycentric regionalpopulation density model and structure optimization method. According to theresults, explore the policy support path on the regional population space structureoptimization in Guangdong province and Pearal River Delta region guided by thesustainable development concept. Obtained the government optimizationsuggestions on economic structural adjustment, transportation system improvementand environmental resource protection and further improved the theoretical systemof the regional population space structure evolution and optimization under theperspective of sustainability.
