摘要
基于城市公共游憩空间内涵界定和构建分类体系,运用POI数据和ArcGIS空间分析方法,探讨了长沙市公共游憩空间的分布格局,研究发现:(1)长沙市公共游憩空间大致呈现"大分散、小集中"分布特征,不同类别游憩资源数量对比悬殊;(2)公共游憩空间分布呈现以五一广场为中心的"圈层式"结构特征,距离城市中心3~6km是游憩空间分布的"隆起带",且不同类别游憩空间分布形态差异显著;(3)各类游憩空间标准差椭圆均呈"西北—东南"偏转方向,但集聚态势与程度对比鲜明。社会游憩需求驱动、政府规划政策调控、"人文一自然"环境基底约束是长沙市公共游憩空间形成的重要机制。
Based on the definition of urban public recreation space and the establishment of a classification system,using POI data and ArcGIS spatial analysis methods to explore the distribution pattern of public recreation space in Changsha city,the study found:(1)Changsha city public recreation space generally presents a"large dispersion,small concentration"distribution characteristics,and the number of different types of recreational resources is quite different;(2)The distribution of public recreational spaces presents a"circular layer"structure characteristic centered on"Wuyi square",3-6 km away from the city center,and the distribution patterns of different types of recreational space are significantly different;(3)The standard deviation ellipses of various types of recreational space are in the"northwest-southeast"direction of deflection,while the agglomeration situation and the degree are in sharp contrast.The drive for social recreational needs,government planning and policy regulation,and the"humane-natural"environmental base constraints are important mechanisms for the formation of public recreational spaces in Changsha.
