Study On Green Space Accessibility Of Linyi West City Park Based On Space Syntax

With the proposal of the development concept of "clear water and green mountains are gold and silver mountains",the park green space in the city,as an important carrier to realize ecological civilization construction,has been endowed with more significance.As a place for residents’ daily leisure activities,residents’ demand for the location,quantity,function,convenience and comfort of the park is increasing.The accessibility of the park can reflect the rationality and fairness of the green space layout of the park,and is an important indicator to evaluate the layout of the park and residents’ living standards.Space syntax theory firstly establishes the topological space model of the city,analyzes the traffic topological network of the city,studies the layout and accessibility of park green space,and then evaluates whether the layout is reasonable and puts forward suggestions for optimization and improvement.Taking Linyi West City as the research object,based on the spatial syntax correlation theory and the satellite image of Linyi West City,combined with the supplement and correction of the field survey data,this paper constructs the spatial model of Linyi West City,and verifies the feasibility of the application of the model by calculating the correlation coefficient between the actual traffic flow and the predicted value;Then,Tyson polygon is used to systematically analyze the service demand characteristics of Linyi West City Park,and the areas with high public service pressure are determined;Then,Depthmap,SPSS,GIS and other software are used to overlay the park distribution points on the basis of the axis model,calculate the values of relevant spatial syntax variables such as the global integration degree,local integration degree,intelligibility degree and spatial efficiency value of the park,analyze the accessibility levels of different administrative districts and different types of park green space in Linyi West City from the four aspects of global,local,perceptual and psychological accessibility,and summarize and sort them according to the accessibility values,The accessibility status of each park green space is obtained and evaluated,and the spatial layout characteristics of Linyi West City park green space are summarized: the accessibility values of Yitang town park green space are high,while Lanshan economic and Technological Development Zone is the worst,the spatial accessibility performance of community parks is the best among the four types of parks,and the values of special parks are the lowest,This shows that the accessibility of special parks in Lanshan economic and Technological Development Zone needs to be improved in the future urban construction.Then,according to the current situation,this paper summarizes the problems existing in the accessibility of green space in Linyi West City park,such as the uneven distribution of green space,the dislocation between park distribution and accessibility,the low perceived accessibility of some parks,the mismatch between park area and psychological accessibility,the obvious difference in the accessibility values of different types of park green space in different administrative regions,and analyzes the causes of these problems,which may be related to the history of urban development and construction,natural landform Traffic status and other factors;Combined with comprehensive evaluation and causes,this paper puts forward corresponding strategies for the spatial layout of green space in Linyi Xicheng Park,such as improving the functional organization of urban transportation system,establishing urban and rural road elevated system,increasing the density of road network in some areas,improving urban transportation infrastructure,enhancing the attraction and accessibility of the park,forming characteristic features,publicizing and improving popularity,enriching the plant greening of green space in the park,increasing the entrance and exit of the park and enhancing openness,Finally,according to the spatial layout,population concentration and the fair and uniform layout of the park,we reflect on the possible problems in the research and make an appropriate prospect for the accessibility of the park in the future.
