Abstract:The allocation of public green space affects urban living quality. In order to promote the optimization and upgrading of the layout of park green space to meet the growing needs of residents for a better life, taking the park green space in the central urban area of Wuhan City as the research object, the GIS spatial analysis and semantic analysis methods were used to explore the accessibility and optimization paths to deal with public heathy events of urban community public space represented by the park green space. The results are shown as follows. 1) The park green space in the central urban area of Wuhan City showed a symmetrical agglomeration distribution along the Yangtze River, and presented a dual-core layout mode of Hanyang and Wuchang; and the spatial distribution of park green space at all levels was perpendicular to the Yangtze River. 2) The layout of park green space in the central urban area of Wuhan City was based on nature, highlighting the features of Landscape Park. 3) At the community scale, the accessibility of park green space in the central urban area of Wuhan City based on walking travel mode decreased from the river to the inland circle, and is effectively complemented by the subway transportation travel mode. The diversified functions of the park should be brought into play to help construct resilient communities by shifting down the layout scale of park green space. It's also required to create public green space that reflects local culture from the aspects of theme, space and media, promoting the cultural transformation of park green space and dovetail with residents' needs in a timely manner, making the park green space “emotionally expressed”, “perceptibly experienced” and “socially interacted”. This study is aimed at enriching the research types of community public spaces and expanding the research horizon of urban ecosystem service functions.
