Study On Spatial Layout And Optimization Of Urban Kindergarten Based On GIS

With the population growth and economic development in recent years,the allocation of kindergarten education resources is unreasonable,and the problem of "difficult to go to school" has become increasingly prominent,which has become a social problem that people pay more attention to.As an important part of the urban function system,kindergarten educational facilities have become an important part of the urban functional system.The scientific and reasonable spatial layout is helpful to realize the balanced distribution of educational resources and realize fairness and justice.This paper aims to study the rationality of the spatial layout of kindergartens and try to optimize the spatial layout by taking Zhanggong District of Ganzhou City as an example.On the basis of analyzing the principle and method of kindergarten layout adjustment,taking Zhanggong district of Ganzhou city as an example,this paper uses ArcGIS and other software to deal with the spatial data and non-spatial data.The present situation of urban kindergartens in Zhanggong District is analyzed from the aspects of educational resources and spatial pattern.Secondly,the population density of streets is analyzed by nuclear density and the service quality of kindergartens is classified.Using two-step mobile search method(2SFCA)to evaluate the accessibility of urban kindergarten layout using actual traffic distance and different service radius.Finally,the location method is used to optimize the layout of kindergartens,and the Huff model is used to divide the scope of kindergarten services and other optimization strategies and suggestions are put forward.The present study shows that the overall educational resources of kindergartens in Zhanggong District are in an unbalanced state.Some areas have coexistence of redundancy and insufficiency.For example,the streets of Ganjiang and Jiefang streets are relatively concentrated.However,there are weak areas in the allocation of school education resources and the convenient degree of schooling in residential areas in Zhanggong district.In view of the problems revealed by the research institute,the author puts forward corresponding countermeasures and suggestions on the imbalance of urban kindergartens in Zhanggong District of Ganzhou City from the aspects of dividing service areas based on location assignment Huff model and optimizing students' access to school.
