| The construction of urban public facilities is very important to urban development,and the rational use of educational resources is of great significance to the residents in the city.In modern society,educational resources in most cities have problems such as uneven distribution and difficulty in getting schooling,especially at the primary and secondary levels.And these problems have always been the concern of a wide range of scholars and society.How to solve this problem must first analyze and study the existing situation.The reasonable spatial layout of educational resources can cause the smallest waste of social resources as much as possible.Based on the concept of rational distribution of social resources,most scholars have conducted a lot of research on different problems of educational resources in different cities based on multiple disciplines and perspectives.The irrational distribution of educational resources has caused social unfairness and unfairness.In these studies,how to determine the service radius of primary and secondary schools,and the starting point and destination of primary and secondary school needs have different criteria.In previous studies,the determination of the radius of primary and secondary schools was single,while the determination of the starting point of primary and secondary schools mostly used streets,residential areas,and centers of residential quarters as the research perspective.This paper analyzes the spatial distribution of the educational resources of primary and secondary schools in the central city of Nanchang.The two methods of buffer analysis and spatial network analysis are used to interpret the service radius of primary and secondary schools.Based on the concept of neighborhood,the service range of primary and secondary schools is determined.Neighborhood coverage and repeatability are studied and analyzed,and the accessibility of primary and secondary schools is evaluated with the neighborhood center as a demand point.The study found that: the educational resources of primary and secondary schools in the central city of Nanchang are unevenly distributed,with the characteristics of clustering in the center and scattered around.Secondly,based on the interpretation of the different service radius of primary and secondary schools,analyze and calculate the service scope of primary and secondary schools in Nanchang’s downtown area.Based on the ratio of the covered neighborhood area,it can be found that the number of neighborhoods with high coverage in middle schools is more than that in primary schools.The number of neighborhoods with high degree of repetition;and the number of neighborhoods with high repetition in middle schools is more than the number of neighborhoods with high repetition in elementary schools.The occurrence of these differences has a great relationship with the scope and quantity of services in middle and primary schools;on the other hand,horizontal comparisons are made from the level of analysis methods.It can be found that the number of neighborhoods with high coverage calculated by the buffer analysis method is more than the number of neighborhoods with high coverage calculated by the spatial network analysis,and the degree of repetition is just the opposite.From the perspective of the overall layout efficiency,the overall layout efficiency of the primary and secondary schools in Nanchang City is deviated,and the overall layout efficiency of the primary and secondary schools analyzed by the two different analysis methods is also inconsistent.The study also found that in terms of travel time,the accessibility from the neighborhood center of Nanchang city center to primary and secondary schools is generally good,but it is located in the marginal area School-age children in the neighborhood largely exceed the prescribed school time for primary and secondary school students;based on the travel distance,it can be calculated that the accessibility of primary and secondary schools is good,but the accessibility of primary and secondary schools in the fringe areas of the central city area obviously exceeds the service scope of primary and secondary schools.This research provides a new research scale for the research of urban public facilities,and also provides a more scientific and auxiliary decision-making basis for the allocation of urban resources. |
