Research On Kunming Urban Parks Layout Based On Accessibility

Urban Parks is the important leisure and recreation,ornamental facilities of urban residents.In order to make full use ofurban parks,we must optimize the layout of the city park green space.In recent years,with the development of GIS,accessibility is gradually extended to the study ofurban parks.Currently,reachability analysis has become an important research tool for the analysis ofurban parks.The study compares the advantages and disadvantages of the relevant research methods of accessibility analysis.Finally,the network analysis method is used to analyze theurban parks in Kunming central area.Taking into account the importance of population factors in the layout of urban park green spaces,Kriging interpolation was used for population simulation analysis by GIS.Finally,combined with the accessibility analysis for comprehensive analysis.The main research content are as follows:(1)The model of urban park green space accessibility in Kunming city was constructed by using network analysis method,we found that Kunming city park green distribution uneven,and some regions have fewer parks.So,we analyzed the reachability of the area that did not cover the area,and the reasons for the formation of the proposed.(2)Simulated the population distribution in the central city of Kunming.We combine the population distribution of Kunming city center with the reachability of Kunming city park green space.Then we calculate the carrying rate of urban park green space in central city of Kunming,evaluate the situation of greenland resources,and put forward some suggestions.The main conclusions are as follows:(1)the traffic accessibility ofurban parks is good,and the walking accessibility ofurban parks is general,it need to be further improved.(2)Population density is an important factor that affects the ability of urban residents to enjoy the green space of the park.(3)Through the discussion of underloading parks,It leads to population evacuation-industrial adjustment-land replacement adjustment program.The study of the population distribution in the central urban area of Kunming is simulated,which is more comprehensive than that of the previous urban system.Then,the study combined with the actual situation in Kunming,Kunming city park green space carrying capacity to determine the standard.So as to further consider the light-load park in order to avoid the phenomenon of waste of public resources.
