| 摘 要： | 通过公式计算了徐州市区的各公交站点功能分，在此基础上运用ArcGIS软件将徐州市区地冈进行单元划分，形成公交站区；然后将各公交站区的功能分进行属性赋值，并进行空间分析，得出徐州市区公交分布南公交便捷度大致从市中心及火车站向外扩展为四级，并且公交站点的便捷度均由站点向外呈衰减趋势，且衰减程度越来越明显，尤其是位于公交便捷度低的区域更为明显；最后将公交便捷度泰森多边形分布图与人口密度泰森多边形分布图进行叠加分析．得出目前徐州市公交便捷度与人口密度分布的匹配适应性以主城区向外围逐渐增强．一些地区的公交便捷度还不能满足人口密度分布的状况。

| Abstract: | The function of each bus stop in main city of Xuzhou was calculate through the formula. On the basis of the function, the map of Xuzhou was divided into units with ArcGIS software, and the public transportation station was formed.And then attributes were given to each bus station. As a result, through spatial analysis, tire convenient level in main city of Xuzhou was obtained and it is divided into four ranks, and the convenient level decays outward, besides, tire attenuation degree is more and more obvious, especially the areas which convenient degree is lower. Finally, by the overlay analysis of Thiessen Polygon of bus convenient degree and Thiessen Polygon of the population density distribution, it turns out that the matching flexibility between them strengthens gradually from the main city to periphery, also, there are some areas that bus convenient level can＇t satisfies the distribution of population density. |
