摘要：基于1995年、2001年、2007年和2014年河南公路交通网络,运用ArcGIS软件平台进行栅格成本距离分析,研究河南省各个区域到其最近城市节点可达性空间格局及其演化规律.结果表明:随时间推移,河南省区域可达性整体水平呈现波动上升趋势.在各时间阶段,可达性水平均具有显著的空间差异,整体呈现多极格局且具有稳定性;处于河南几何中心的郑州、许昌可达性值一直相对较低,边缘地区的可达性值相对较高,但随时间推移区域间差异有所缩小.从可达性变化速率来看,区域可达性变化速率呈v型降低,但空间上存在显著差异,1995—2001年河南省公路网络可达性变化速率较快,且空间分布具有较强的交通干道指向性,在此阶段公路网络完善极大地提高了各区域可达性;2001—2007年可达性值提升较1995—2001年不显著,且某些地区有所下降,与道路改建有关,整体可达性变化速率慢;2007—2014年可达性值改善优于2001—2007年,可达性变化速率较快.总的来看,边缘地区可达性值变化速率比中心地区变化速率快,区域可达性变化幅度与可达性初值有关,同时高速公路建设与完善、国家政策以及区域自然地理条件对可达性具有重要影响.
This article studies the traffic network in the ban space and the evolution of principle in the Henan various regions to its nearest reachable node pattern of ur- 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 muhipolar and stable in Henan. Zhengzhou, Xuchang in the geo- metric 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 distribu- tion 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 signif- icant. 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.
