“呼包鄂”城市公交站点空间分异特征及可达性研究

Study on Spatial Differentiation and Accessibility of Urban Public Transport Stations in"Hohhot,Baotou and Ordos"City

不同城市的公共站点空间分布对城市的交通状况有着不同影响,对比不同城市公交站点的空间分布特征和空间可达性,总结得出利于公共交通的空间特征。以内蒙古中西部核心区经济圈的呼和浩特市、包头市、鄂尔多斯市为研究对象,通过知网统计年鉴、百度地图API开放平台等收集基础数据,采用平均最邻近、不平衡指数、核密度分析、标准差椭圆研究城市公共交通空间分布特征,使用公交站点覆盖率及空间可达性来分析城市公交站点的可达性。研究结果显示:(1)城市公交站点多为聚集分布,越靠近城市边缘密度越低;(2)城市公交站点的分布均匀度越好,空间可达性就越高;(3)城市公交站点空间分布的标准差椭圆形态与城市形态越契合,其空间可达性就越高。

The spatial distribution of public bus stops in different cities has different impacts on urban traffic conditions.The spatial distribution characteristics and spatial accessibility of public bus stops in different cities were compared,the space characteristics of public transportation are summarized.Based on Hohhot,Baotou and Ordos City in the central and western Inner mongolia Economic Circle,basic data were collected through the hownet statistical yearbook and the Baidu map API Open platform,the spatial distribution characteristics of urban public transport are studied by means of average nearest neighbor,disequilibrium index,kernel density analysis and standard deviation ellipse,the urban bus station accessibility was analyzed by using bus station coverage and spatial accessibility.The results show that:(1)Most of the bus stops in cities are clustered;(2)the better the uniformity of the distribution of urban bus stops,the higher the spatial accessibility;(3)the more the spatial distribution of urban bus stops fits the ellipse shape and the urban shape,the higher the spatial accessibility.
