摘要
探析旅游古镇活力分布的时空特征并明确其建成环境驱动因素,对推动旅游古镇空间品质提升及其均衡发展具有重要意义。文章以云南省丽江市大研古镇为例,采用腾讯位置大数据表征古镇日、夜间空间活力分布情况,借助全局Moran's I指数、局域关联指数(Getis-Ord GI^(*))揭示其活力的时空分布特征,并使用地理探测器明确其建成环境驱动因素,结果表明:(1)大研古镇日、夜间活力分布均具有明显空间异质性。日间人群活动呈现出热点区“多核散布”、冷点区“团状聚集”的空间分布特征,夜间人群活动热点区呈现出明显的“核心—次核心”多层极核结构。(2)空间可达性、功能设施和物质界面对大研古镇日、夜间活力分布的影响具有明显的差异。其中古镇日间活力受到接近度(r=n)、总体设施密度和建筑密度的影响较大;夜间活力更多受到休闲设施密度、接近度(r=400m)和建筑密度的影响。(3)各项驱动因素之间的交互配合均对大研古镇日、夜间活力有着双因子增强或非线性增强的正向效应。
Analyzing the temporal and spatial characteristics of the vitality distribution of ancient tourism towns and clarifying the driving factors of their built environment are of great significance to promoting the spatial quality of ancient tourism towns and their balanced development.Taking the ancient town of Dayan in Lijiang City as an example,Tencent location big data is used to characterize the spatial vitality distribution of the ancient town during the day and night,and the global Moran's I index and the local correlation index(Getis-Ord GI^(*))are used to reveal the temporal and spatial distribution of its vitality,and using geographic detectors to clarify the driving factors of its built environment,the results show that:(1)The day and night vitality distribution of Dayan Ancient Town has obvious spatial heterogeneity.Daytime crowd activities show the spatial distribution characteristics of‘multicore spreading’in hot spots and‘cluster gathering’in cold spots,and night crowd activities in hot spots show an obvious‘core-sub-core’multilayer polar core structure.(2)There are obvious differences in the influence of spatial accessibility,functional facilities and material interfaces on the day and night vitality distribution of Dayan Ancient Town.Among them,the daytime vitality of ancient towns is greatly affected by proximity(r=n),overall functional density and building density;nighttime vitality is more affected by the density of leisure facilities,proximity(r=400m)and building density.(3)The interaction of various driving factors has a positive effect of double-factor enhancement or non-linear enhancement on day and night vitality of Dayan Ancient Town.
