摘要
传统超市空间分布研究方法存在一定局限性,该文运用空间句法穿行度指标,辅以核密度估计法、标准差椭圆法,分析了南昌市不同级别超市空间分布规律,得到研究结果为:1)不同级别超市核心-边缘分布范围不同,规模越大,核心分布范围越小;2)在市级和区级运动集聚网络中,超市规模级别越高,对高穿行度道路依赖性越大;3)小型超市紧邻高穿行度道路比例在各类型超市中最低;4)中型超市区位选择偏好多为距高穿行度道路1步距。研究表明,空间句法可以较好地从微观尺度揭示超市同高穿行度道路的空间定量关系,能够为超市的选址提供更具有操作性的建议。
There are certain limitations in the traditional researches about the spatial distribution of supermarkets.In this paper,based on the space syntax,the kernel density estimation method and the standard deviation ellipse method were used to analyze the spatial distribution patterns of supermarkets at different levels in Nanchang city.The results showed that:1)The core-edge distribution range of different levels of supermarkets was different,and the larger the scale,the smaller the core distribution range.2)In the municipal and district level sports network,the higher the scale of supermarket,the greater the dependence on the road.3)Small supermarkets close to high betweenness roads had the lowest proportion.4)Most medium-sized supermarkets located one step away from the high betweenness roads.Space syntax could better reveal the quantitative spatial relationships between supermarkets and the high betweenness roads,and provide more practical suggestions for supermarket site.
