基于POI数据的旅游城市公共游憩空间分布研究——以桂林市中心城区为例

Research on the Spatial Distribution of Public Recreation in Tourist Cities Based on POI Data:A Case of Guilin’s Downtown Area

公共游憩空间作为衡量城市宜居性和居民幸福感的重要内容,其品质的有效提升是城市发展亟待解决的问题。基于旅游城市特征,文章对公共游憩空间进行分类,运用ArcGIS平台进行特征分析,解析桂林市公共游憩空间的分布格局。研究发现:①桂林市公共游憩空间总体呈现出“一核多点”分布特征,各类型之间存在较大的区际差异;②桂林市公共游憩空间以王城—东西巷为核心,在临桂区、桂林融创文旅城等多处空间形成点状分布;③各类型公共游憩空间集聚程度较为明显,标准差椭圆呈现向“西北—东南”方向偏转。最后,提出注重各类型游憩资源的保护与开发、增加设施密度和可达性、优化类型组合结构、提升供给质量促进行为活动的发生等建议。

As an important indicator to measure the livability of cities and the happiness of residents,the improvement of the quality of urban public recreation spaces is an urgent problem to be solved in urban development.Based on the characteristics of tourist cities,the public recreation space is classified,and the ArcGIS platform is used for feature analysis to analyze the distribution pattern of public recreation space in Guilin.It is found that:①the public recreation space in Guilin generally shows the distribution characteristics of“one core and multiple points”,and there are large regional differences between different types;②the public recreation space in Guilin City takes Wangcheng-Dongxi Lane as the core,and forms a dotted distribution in many spaces such as Lingui District and Guilin Sunac Cultural Tourism City;③the degree of agglomeration of various types of public recreation spaces is more obvious,and the standard deviation ellipse shows a“northwest-southeast”deflection direction.Finally,the paper proposes to pay attention to the protection and development of various types of recreational resources,to increase the density and accessibility of the facilities,to optimize the structure of type combinations,and to improve the quality of supply to promote the occurrence of behavioral activities.
