Research On The Location And Optimization Of Micro Public Space In Hongshan District Of Wuhan Based On GIS

City is a complicated complex,micro public space as part of this complicated complex,as the body's capillaries are generally scattered in every corner of the city,seemingly small but plays an indispensable role.The location technology is widely used in health,city infrastructure,public buildings and other relevant research,but the location for micro public space involves almost no infrastructure.Reasonable location,on the one hand,can make the fastest and most convenient city residents to enjoy the city infrastructure,on the other hand,is conducive to save social resources,fairness and justice the realization of social.This paper takes micro public space in Wuhan District of Hongshan City as the research object,putting forward the location and optimization of micro public space research based on GIS.In the domestic and foreign micro public space related literatures and study location of relevant theory,comprehensive consideration of many factors.First the status of micro public space arrangement,to eliminate inappropriate the status quo of the micro public space in the city of micro public space and combing the city road network on the basis of simulation,the status quo of the micro public space is loaded into the GIS database.Then,according to the present situation of the research,as well as related drawings,selection can be used as micro public space preparationAfter finishing point,loaded into the GIS database,optional points as micro public space location.Analyze the buffer analysis and the reachability status of micro public space and public space micro alternative site,carrying out alternative point adjustment according to the analysis result,get a mini public space optimization scheme preliminary.Combined with the District of Hongshan,the first batch of micro public space is to select the eight points of the pilot construction opportunity,the author concluded in early preliminary micro public space location further screened a site eight micro public space pilot.Using the GIS network analysis technology,the first methord is to use the minimum number of facilities within the scope of the study model,obtained a satisfied the least number of micro public space residents ten minutes walking conditions required.Then,using minimizing the impedance model,and the maximum coverage model for the selected micro public space location is deduced and optimization,select the most appropriate 8-micro public space construction testSite selection and verification,to ensure the location of the scientific,so that the city workers using that as a reference,and making scientific decisions.In this paper,the author uses GIS network analysis process of Hongshan micro public space location and Optimization in Hongshan District of micro public space of sorting out the system,and uses the GIS in the road network of Hongshan district established a framework for later,the Hongshan area location and related research and micro public space the reference and methods for reference.
