Analysis Of Urban Park Green Space Pattern In Shijiazhuang Based On Accessibility

Park green space is an important part of urban green space system,which has the ecological functions of maintaining carbon and oxygen balance,absorbing toxic gases,sterilization,adjusting microclimate,etc.it is an important place for urban residents’ daily recreational activities,providing residents with recreation,cultural education,disaster reduction and refuge and other functions.The quantity,quality and spatial layout of park green space directly affect the quality of urban environment and residents’ life.With the rapid increase of the number of urban residents,the existing urban park green space often does not meet the new requirements of the times,so the design and construction pattern of urban park green space need to be solved.This paper takes the pattern of urban park green space in Yuhua District of Shijiazhuang City as the research content,uses a variety of analysis methods,based on the accessibility to comprehensively study the existing problems of the pattern of urban park green space,and combines theory with practice to explore the optimization strategy of the pattern of urban park green space.This paper is divided into five parts.The first part takes the urban park green space pattern as the research object,and comprehensively expounds the related basic theory and research;The second part takes Shijiazhuang city park green space as the research subject,expounds the related concepts and research methods,investigates the research status,and determines the research subject from the accessibility level;The third part is the objective level of urban park green space accessibility research,through the comparison of six main accessibility analysis methods,select GIS network analysis platform for data analysis,and establish data regression model;The fourth part is the subjective level of urban park green space accessibility analysis,through the field research results of factor analysis,build urban park green space accessibility evaluation system,determine the influencing factors.Make up for the lack of perceptual factors in the research;In the last part,taking Yuhua District of Shijiazhuang City as an example,based on the accessibility based optimization strategy and evaluation system of urban park green space pattern summarized in the above research,the optimization design and application are carried out on the basis of relevant data analysis.Through the above urban park green space layout optimization strategy and application research,through improving the accessibility of urban park green space to optimize the urban park green space pattern,to provide more convenient urban park green space services for urban residents.
