广州市南沙区生活设施空间分异特征及影响因素探测

Spatial Differentiation Characteristics and Influence Factors of Living Facilities in Nansha District, Guangzhou

识别生活设施的空间分异特征对于优化城市资源配置、提高居民生活幸福感具有重要意义。本文以广州市南沙区10类生活设施作为研究对象,利用基尼系数、区位裔、核密度分析、信息熔及地理探测器等方法,探究南沙区生活设施空间分异特征及影响因素。结果表明:(1)南沙区生活设施与人□分布相匹配,但部分设施在地理分布上存在不合理现象。(2)各类生活设施的空间聚集水平差异明显,热点分布呈多中心格局。(引在街道尺度上,人□密度大、交通通达,性好、开发历史较早的街道(镇),其生活设施完备性较好。(4)路网密度、人流量、人□密度及海拔高度是南沙区生活设施空间分异特征的重要影响因素。

To identify the spatial differentiation characteristics of living facilities is of great significance for optimizing the allocation of urban resources and improving the residents' sense of well-being. In this paper, we take 10 types of living facilities in Nansha district of Guangzhou as the research object, and employ the Gini coefficient, location quotient, nuclear density analysis, information entropy and GeoDetector to explore the spatial differentiation characteristics and influencing factors of living facilities in Nansha district. The results are shown as follows:(1) Living facilities match the population distribution in Nansha district, but some of them are unreasonable in geographical distribution.(2) The spatial agglomeration levels of all kinds of living facilities apparently vary from one another, and the hot spots are distributed in a multi-center pattern.(3) On the street scale, the streets (towns) with high population density, good traffic accessibility and a long development history have better living facilities.(4) The road network density, the human flow, the population density and the altitude all have a great impact on the spatial differentiation characteristics of living facilities in Nansha district.
