摘要: 公共服务设施作为城市的一道风景线,对于城市经济的发展具有重要作用。通过高德地图开放平台获取昆明市POI数据,采用核密度分析和标准差椭圆分析方法,结合ArcGIS 10.2软件探讨了昆明市公共服务设施的空间分布格局,并计算昆明市公共服务设施POI熵指数。结果表明,昆明市公共服务设施POI密度最大的地区是五华区,POI密度最小的地区是禄劝彝族苗族自治县;昆明市公共服务设施整体呈“一核两轴多极”的空间分布模式和“南部多而密集、北部少而稀疏”的空间分布格局;昆明市各类公共服务设施存在单核、双核和多核3种空间聚集模式,在空间上大致呈“西南—东北”走向分布;昆明市城市功能混合度在空间上呈“中心-边缘”分布。人口结构、经济发展水平和收入状况是影响公共服务设施空间布局的重要因素。最后,针对昆明市公共服务设施提出了3条提升路径。

Abstract: As a scenic line of the city, public service facilities play an important role in the development of the urban economy. The POI data of Kunming City were obtained through the open platform of Gaode map, the spatial distribution pattern of public service facilities in Kunming City was discussed by using the methods of kernel density analysis and standard deviation ellipse analysis, combined with ArcGIS 10.2 software, and the POI entropy index of public service facilities in Kunming City was calculated. The result showed that the area with the highest POI density of public service facilities in Kunming City was Wuhua district, and the area with the lowest POI density was Luquan Yi and Miao autonomous county. The overall public service facilities in Kunming City presented a spatial distribution pattern of “one core, two axes and multi-poles” and a spatial distribution pattern of “more and dense in the south and less and sparse in the north”. There were three spatial aggregation modes in various types of public service facilities in Kunming City, such as single-core, dual-core,and multi-core, which were roughly spatially distributed in the direction of “southwest—northeast” the degree of urban function mix in Kunming City was spatially distributed as “center-edge”. Population structure, economic development level and income status were important factors that affected the spatial layout of public service facilities. Finally, three upgrade paths were proposed for public service facilities in Kunming City.

Key words: public service facilities, nuclear density analysis, POI, Kunming City
