Research On Evaluation Of Urban Park Green Space Accessibility Based On Travel Mode

The innovation and revolution of science and technology have promoted the rapid development of urbanization and brought about the transformation of urban residents’ living patterns.As people’s leisure time gradually increases,the demand for recreational green is also increasing.Urban residents pay more and more attention to the ecological environment of the city,and put forward higher requirements for park green space.The accessibility of urban park green space and the rationality of its spatial distribution have gradually become the focus of attention of urban residents and society.This article first reviews the current status and progress of research on the accessibility of green spaces in urban parks at home and abroad,analyzes the existing research deficiencies,clarifies the research purpose and significance,content and methods,and technical routes;secondly,it proposes the accessibility of green spaces in urban parks based on travel modes Research,and introduced the research process in detail;then explained the data source and processing of leisure travel mode and the spatial distribution of urban population density,analyzed its current characteristics;then,explained the source of basic data of urban roads and parks and green space,The distribution status is analyzed,and the research on the accessibility of urban park green space based on travel modes is discussed.The supply-demand relationship between urban park green space and urban residents is discussed.Finally,the shortcomings of urban park green space are analyzed,and corresponding optimization suggestions are proposed..This article uses the SPSS platform to use Pearson chi-square test and multiple correspondence analysis to summarize the residents’ travel modes.The Arc GIS platform Kerry uses the golden method to obtain the spatial distribution of urban population density.The network analysis method is used to study the urban park green space This paper discusses the supply and demand relationship between park green space and urban residents,and analyzes the rationality of the spatial distribution of park green space.Taking Wu’an’s main urban area as an empirical case study,the results show that: Residents of the Wu’an main urban area travel frequently and regularly by walking and riding within 20 minutes,while the comprehensive accessibility of urban parks and green spaces is lesser good by walking,and good by riding;travel modes ofurban residents,population density,the scale and service radius of urban park green space are important factors affecting the accessibility of urban park green space.using the service radius to measure the multiple reach coverage of urban park green space can effectively characterize and measure the rationality of urban park green space resource allocation;The travel range of most residents in the actual travel mode is smaller than the reachable range of urban park green space calculated under the same travel mode,and is even smaller than the reachable range of urban park green space calculated under the service radius.Quantify the accessibility of green space in urban parks,explore the supply and demand relationship between the supply of social services and the pro-green demand of residents,analyze the current status of the spatial distribution of green spaces in urban parks,study the rationality of the allocation of park green space resources,and further improve the lives of urban residents in the future Quality and improvement of urban green space system planning and construction provide realistic necessary requirements and theoretical and practical significance.
