摘要
选取河南省公路客运为研究对象,通过河南省长途汽车客运班线调查的O-D数据和统计数据,在ArcGIS平台上通过VBA编程,运用最大输出量等指标,自动产生河南省空间运输联系网络图,以确定河南省公路客运联系模式。研究表明,郑州市作为省会极化效应明显,辐射范围波及全省;河南省公路客流的距离衰减规律明显,短途流所占比例较大。
In order to generate spatial transportation network diagram of Henan Province, this paper uses AO ＋ VBA to program in ArcGIS with passenger transport O-D data and statistical data, and finally determine the pat- tern of spatial transport linkage of highway passenger in Henan Province. The conclusions are as follows ： 1 ） As the provincial capital of Henan, Zhengzhou shows an obviously polarization effect, and its radiation range covers over the whole province. 2） Spatial attenuating tendency of highway passenger traffic in Henan Province is very obvious, passenger traffic with the distance reduces very quickly, it explains that the short distance passenger traffic account for a large proportion.
