基于公路网络的河南可达性空间格局及其演变研究
Study on the spatial pattern and evolvement accessibility based on highway network in Henan
摘要
Abstract
This article studies the traffic network in the various regions to its nearest reachable node pattern of urban space and the evolution of principle in the Henan Province, using the ArcGIS platform to analyze, the grid cost distance and taking 1995, 2001, 2007, 2014 as the time section.The results indicates that the overall level of regional accessibility presents a rising trend in Henan.The traffic network has significant spatial difference in different time stages, the overall presentation is multipolar and stable in Henan.Zhengzhou, Xuchang in the geometric center of Henan, their reachability value have been relatively low, the edge area of accessibility value is relatively high, with the time going, the zone difference became narrowed.From the point of the change rate, the differences of area were reduced, but there is a significant difference in the space, from 1995 to 2001,Henan Province accessibility of highway network overall spatial pattern showed significent change, the spatial distribution showing the strong directions of traffic arteries.From 2001to 2007, the reachability value promotion is lower than the last phase (2001-1995), from 2007 to 2014,the reachability value improvement was essentially significant.The study shows that the reachability changes amplitude relate to the initial.The further illustrate shows that the traffic with stability and accessibility and the initial value of the opinion, and its also shows that the construction of the highway,the national police and regional natural geographical conditions have important influence to the accessibility.关键词
