摘要 为促进城市新区公共服务设施空间布局合理化,提升新区发展质量,基于重庆市2016、2019及2021年POI数据,利用区位基尼系数法、标准差椭圆法、平均最近邻分析法及核密度估计法等GIS空间分析方法研究中心城区外围圈层城市新区公共服务设施空间分布演变特征及影响因素。结果表明重庆市中心城区外围圈层城市新区公共服务设施:数量先增加后减少,盈利性公共服务设施下降幅度更加明显;总体分布不均衡,但逐渐向均衡化方向发展,盈利性公共服务设施不均衡性更强;分布范围逐渐扩大,呈现“东北-西南”发展方向,但方向性逐渐减弱,公益性公共服务设施扩散性更强但方向性更弱;各类公共服务设施显著集聚,盈利性公共服务设施集聚性更强;“多核”态势明显,北区集聚程度最高,西区发展速度最快,两类公共服务设施在西区分布差异明显。 The research aims to provide the reference for the rational layout of public service facilities in new urban areas and improve the development quality of new urban areas.On the basis of POI data of Chongqing in 2016,2019 and 2021,the evolution characteristics of the spatial distribution of public service facilities in new urban areas in the periphery of downtown area are analyzed by the GIS analysis methods including Gini coefficient method,standard deviation ellipse method,mean nearest neighbor analysis method and kernel density estimation method.The results show that the number of public service facilities increases firstly and then decreases,and the profitable public service facilities decline more obviously.The overall distribution is uneven,but it gradually develops in a balanced direction,while profitable public services facilities are more uneven.The distribution range is gradually expanding,showing the development direction of"Northeast-Southwest",but this development direction is gradually weakening.And the spread of public welfare public service facilities is stronger but the direction is weaker.Various public service facilities are notable agglomeration,and profitable public service facilities are more concentrated.The"multi-core"trend is obvious with the highest degree of agglomeration in the North District and the fastest development in the West District.The distribution of the two types of public service facilities in the West District is significantly different.
