摘要
公共绿地空间的配置影响城市人居生活质量.该文以武汉市中心城区公园绿地为研究对象,运用GIS空间分析与语义分析方法,探究以公园绿地为代表的城市社区公共空间的可达性与应对公共卫生事件的优化路径.研究表明:1)武汉市中心城区公园绿地空间呈现沿长江对称集聚分布,且呈现汉阳、武昌双核布局模式,各级公园绿地空间分布均垂直于长江走向.2)武汉市中心城区公园绿地布局形式以自然为基底,凸显了山水公园的特征.3)社区尺度下,基于步行出行方式武汉市中心城区公园绿地的可达性呈现沿江向内陆圈层式递减规律,并以地铁出行方式有效补充公园绿地整体可达性.应通过下移公园绿地布局尺度,发挥公园多元功能性助力韧性社区建设;从主题、空间、媒介等方面打造体现地方文化的公共绿地,推动公园绿地的文化转向;适时对接居民需求,将公园绿地空间打造成“可情感表达”“可感知体验”“可社会交往”的公共空间.旨在丰富社区公共空间的研究类型和拓展城市生态系统服务功能的研究视域.
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.
