基于POI数据的兰州市主城区生活设施配套分异化研究

Research on differentiation of urban life facilities in Lanzhou based on POI data

借助当下大数据对城市研究数据和方法的扩充,利用兰州市主城区高德POI分类清洗数据,应用核密度法,对主城区内居住、工作、医疗与休闲4类设施的空间分布现状进行研究;并根据4类设施的空间相关性赋权,进而对4类设施的空间配套情况进行评价。分析得出:兰州市生活设施综合评价最高的区域是城关区,生活设施配套度评价的高值区域在空间分布上呈单中心。

With the help of the current large data to expand the urban research data and methods,using the classified cleaning data of Gaode POI in Lanzhou City,and applying the nuclear density method,this paper studies the spatial distribution status of four types of facilities in the main urban area,including residential,work,medical and leisure facilities,and empowers the four types of facilities according to their spatial correlation,and then evaluates the spatial matching situation of the four types of facilities.It is concluded that the highest comprehensive evaluation area of living facilities in Lanzhou is Chengguan District,and the high value area of evaluation of living facilities matching degree is single center in spatial distribution.
