基于POI数据的杭州市中心城区公共服务设施空间分布研究

Spatial distribution of public service facilities based on POI data——A case study of Hangzhou

本研究基于杭州市部分POI数据,利用最邻近比率和核密度分析,探讨研究区内公共服务设施的空间分布情况。研究结果表明,杭州市中心市区公共设施分布为聚集状态,各类设施在钱塘江以北分布较广,较为完善,钱塘江以南则需要进一步完善。

Based on POI data in Hangzhou,this study uses the nearest neighbor ratio and nuclear density analysis to explore the spatial distribution of public service facilities in the study area.The research results show that the public facilities in the study area are concentrated.The various facilities are widely distributed north of the Qiantang River and are relatively complete.The south of the Qiantang River needs further improvement.
