Research On The Spatial Equity Of Urban Public Service Facilities

Urban public service facilities are an important carrier to guarantee the normal operation of the basic production and life of urban residents,and are an area that has been the focus of attention in urban planning and construction work.Since the beginning of the 21 st century,the urbanization process has gradually accelerated and the residents’ material living standards have been raised,which has brought new challenges to the number,quality and types of residential functions and surrounding facilities.The configuration of public service facilities has an obvious "positive externality",which exacerbates the gap between regions.A reasonable facility configuration is of great significance to eliminate regional gaps,improve residents’ living happiness,and achieve social equity and regional justice.The Nineteenth National Congress of the Communist Party of China pointed out that the main contradictions in our society have been transformed into the contradiction between the people ’s increasing need for a better life and the imbalanced and inadequate development,Paying attention to residents’ opportunities for the number,type and quality of public service facilities,and rationally configuring public service facilities are of great significance to improving the living standards of residents.Since Taiyuan entered the 21 st century,the pace of urban development has gradually accelerated,and the construction land in the center of Taiyuan has gradually become saturated.Under this background,Taiyuan proposed the urban planning and deployment of "sweeping westwards,expanding northwards and expanding eastwards" and rebuilding villages in the city,so that a large number of areas in Taiyuan city have ushered in new development,but these areas have developed relatively late.The completeness of the surrounding facilities directly affects the life experience of local residents.Under the new environment and new era,there are higher requirements for supporting facilities of public services in Taiyuan City,and the research results of public service facilities in Taiyuan City are still scarce.This article hopes to provide practical reference for the urban construction of Taiyuan City and enrich the theoretical research on the spatial equity of public service facilities in China.In this paper,14,000 residential areas collected in Taiyuan City are used as researchsamples,7 types of public service facilities POI points are used as research objects,and various streets,townships and towns in Taiyuan City are used as research units.Appling big data acquisition technology,Arc GIS and Geo Da spatial analysis tools and SPSS data statistical tools,using nuclear density analysis,bivariate spatial autocorrelation,network analysis methods,Evaluation of the spatial fairness of public service facilities in Taiyuan City from three aspects of spatial matching,spatial diversity and spatial accessibility of public service facilities.The results show that:(1)Basically,all types of facilities in Taiyuan City have obvious agglomeration characteristics,especially in medical facilities;(2)To a certain extent,Taiyuan City has problems with the transitional allocation of facilities in the new urban area,such as the area around Longcheng Street in Xiaodian District;Over-population,lagging facilities in the old city,such as Jianhe Street and Yangjiayu Street in Xinghualing District;(3)Within the reasonable travel range of residents,Taiyuan City has a low coverage of spiritual culture,leisure and entertainment facilities,mainly reflected in the lack of sports facilities,cultural facilities and park square facilities;(4)In remote areas of Taiyuan City,the spatial accessibility level is also poor,such as Yangqu Town,Jinci Town,Beige Town,Baiban Township,Xiyan Township,The construction of basic roads needs to be strengthened.
