道路客运发展的时空特征分析

Analysis on Spatio-temporal Character of the Development of Road Passenger Transportation

从区域内部空间单元的相互关系出发,应用区位商、非平衡性系数、空间自相关等理论和方法分析道路客运发展的时空特征,建立一套区域道路客运发展时空结构分析体系,主要包括非平衡性体系、相关性分析体系、分析方法及衡量指标。空间非平衡是通过一些衡量指标来体现的,给出了变异系数、加权变异系数、锡尔(Theil)系数、基尼(Gini)系数等系数的定义和表达式,其中又以锡尔指数与基尼系数最能表现空间结构的不平衡性。最后,以浙江省为实例进行分析,深入探讨道路客运发展的规律性。

Proceeding from the correlation of local spatial zone, some theories and methods, such as location quotient, imbalance coefficient, spatial autocorrelafion is applied to analyse the spatio-temporal character of the development of road passenger transportation. A system to analyse the spatio-temporal structure of the development about road passenger transportation is built, which includes imbanlanee system, relation system and some measured indexes. The definition and expression of some measured indexes such as variant coefficient, weighted variant coefficient, Theil coefficient, Gini coefficient are given to embody spatial imbanlance.Among these coefficients Theil coefficient and Gini coefficient are the best forms to represent the imbanlance of the spatial structure. In the end, Zhejiang Provience is taken as an example to profound discuss the regularity of the development of road passenger transportation.
