区域旅客运输空间联系特征提取方法研究 ——以云南省为例

区域旅客运输空间联系特征提取能够为区域交通规划及客运组织提供基础数据.为高效提取区域旅客运输的空间联系特征，引入平均运距这一重要的运输特征指标，通过对质量因子进行重新标定，建立引力模型的改进方法，并运用高速公路客车流量数据与该特征进行匹配分析，最后以云南省为实例进行验证.结果表明，以昆明为核心，云南省旅客运输空间联系强度具有明显的圈层结构；道路客运联系的空间分异特征显著，呈现出与“中心-腹地”经济关系相吻合的空间格局；滇中城市群客运吸引力较大，滇西地区客运吸引力普遍较小；客车流量数据分析结果与旅客运输空间联系特征总体吻合.

Extraction Methods for Regional Passenger Transportation Spatial Linkage Feature:the Case of Yunnan Province

Extraction features of passenger transportation spatial linkage could provide basic data for regional traffic planning and passenger organization. In order to extract the spatial linkage features of passenger transportation effectively, the average mileage of passenger transportation which is an important transport feature indicator is introduced in this paper, by recalibrating the quality factors, and the conventional gravity model is also improved to establish the extraction method. Then the expressway passenger traffic data is used to match with the features in this paper, and Yunnan province is taken as an example. The results show that the spatial differentiation characteristics are significant in transport linkage in Yunnan, which is consistent with the economic relationship of the "center-hinterland", and with Kunming is the core city, regional spatial transport linkage has obvious structural intensity; the attraction intensity of passenger transportation is stronger in the central region of Yunnan province, while attraction intensity is weaken in western Yunnan; bus traffic flow data in Yunnan province is also in consistent with the spatial linkage features got above.
