ANALYSIS ON THE DISTRIBUTION OF VITALITY SPACES IN MAIN URBAN AREAS OF CHENGDU CITY BASED ON POI BIG DATA
-
摘要: 空间活力是影响城市发展的重要因素,基于兴趣点(POI)数据,依托ArcGIS平台,从数学空间、现象数据两角度,利用层次分析、变异系数、最邻近系数、核密度分析、空间自相关分析等方法对成都市主城区的活力空间分局进行研究,总结城市活力空间的分局特征,并探讨影响因素。得出:1)成都主城区兴趣点设施的空间分布表现出明显向心性;2)各类设施在空间上的分布形态和集聚中心有所差异;3)成都市空间活力分局为“三圈层”模式;4)活力空间与人口分布、路网密度存在较强的空间正相关关系。Abstract: Spatial vitality is an important factor influencing urban development. Based on POI data, relying on the ArcGIS platform, the distribution of urban vitality spaces in the main urban areas of Chengdu was studied from the perspectives of mathematical spaces and phenomenon data by using the analytic hierarchy process, coefficients of variation, nearest neighbor coefficients, kernel density analysis, spatial autocorrelation analysis and other methods. The distribution characteristics of urban vitality spaces were summarized, and the influencing factors on urban vitality were discussed. The conclusions were as follows:1) the spatial distribution of facilities of interest points in the main urban area of Chengdu was of obvious centripetallity; 2) there were some differences in spatial distribution patterns and agglomeration centers of various facilities; 3) the distribution of Chengdu's spatial vitality was of "three-circle mode"; 4) the vitality space had a strong spatial positive correlation with the population distribution and road-network density.
