| 摘 要： | 利用GIS技术，以河南省镇平县为例，在评价交通网络可达性的基础上，总结了影响可达性的三个因素：是否与高等级干线公路邻接；在区域中的地理位置居中还是偏远；所在区域道路网络的整体连通性。在这些因素指引下所作的路网调整，明显改善了交通网络的可达性，优化了城镇节点的交通区位。 |

| Abstract: | Based on GIS and taking Zhenping county of Henan province, after estimating accessibility of transporation network, three factors which affect accessibility are found out： Whether adjacent to high-ranked main roads ; s the location in the region centered or marginal？ The general connectivity of transportation network of the area which he node belongs to. Adjustion to the network under the guideline of these factors indicates： the accessibility of ransportation network is obviously improved and transportational location of towns are notably optimized. |
