摘　　要：基于杭州市六类公共服务设施的POI数据,采用最近邻指数、标准差椭圆和核密度分析等地理空间分析方法,分析了杭州市公共服务设施的空间分布特征,得出以下结论:(1)杭州市六类公共服务设施均有在主城区高度集聚的特征。(2)六类设施布局方向均为西北-东南向,公共交通设施的辐射范围最广,方向性最突出。(3)公共服务设施分布均存在明显的中心-边缘结构特征,但不同类设施分布存在差异。Based on the POI data of six types of public service facilities in Hangzhou,geospatial analysis methods such as Nearest Neighbor Index,Standard Deviation Ellipse and Kernel Density Analysis were used to analyze the spatial distribution characteristics of public service facilities in Hangzhou.The results show that:(1)All six types of public service facilities have the characteristic of being highly clustered in the main urban area.(2)All six types of facilities are laid out in a northwest-southeast direction,with public transport facilities having the widest radiation range and the most prominent directionality.(3)The distribution of public service facilities has obvious center-edge structural characteristics,but there are differences in the distribution of different types of facilities.
