Study On The Accessibility Of Green Space In Urban Parks Based On Spatial Syntax

Park green space is an important green infrastructure for the construction of urban human settlements.It is the main landscape element that constitutes the city's natural ecosystem.It is also an important cultural place for citizens to entertain and recreational activities.It exerts multiple social,economic,and ecological benefits.Early scholars often used qualitative analysis methods to study the accessibility of urban open spaces or individual typical parks,focusing on understanding the spatial structure characteristics of urban park green spaces from the perspective of accessibility,with the construction of new urbanization and " With the slogan “Park City”,citizens 'appeals and pursuits for quality of life are increasing day by day.Whether they can enter the green space of city parks conveniently and quickly to enjoy “space services” has gradually become an important indicator and academic research hotspot for evaluating the quality of life of citizens and the comprehensive strength of the city.Based on the principles of science,balance,easy access to data and ease of operation,31 urban park green spaces in the downtown area of Hefei were selected as the research object,and the classic spatial syntax theory and technology were used to support the traffic roads in the downtown area of Hefei.On-site surveys and data collation were carried out on the net and park green space,supplemented by Arc GIS and Depthmap1.0 software to measure the walkability,global reachability and local reachability of the research object respectively,and Hefei was obtained according to the measurement results and comprehensive evaluation The construction speed of the park green space in the downtown area lags behind the urban development speed,the uneven spatial distribution,the "misalignment" phenomenon with the road accessibility and the current situation of the weak green space in the community.The foundation and the direction of future urban development,from the four aspects of improving the attractiveness and utilization rate of park green space,optimizing the spatial pattern of park green space,improving the urban road transportation network,and rationally guiding land use planning,have proposed strategies for optimizing the layout of park green space in downtown Hefei Value reference,with a view to enhancing the downtown area of Hefei The spatial accessibility and level of service fairness of the park green space make the planning of park green space layout in the downtown area of Hefei more scientific and reasonable,and can meet the current urgent needs of citizens for cultural and leisure life,and promote Hefei City 's “national ecological garden city” and “ "Park City".
