摘　　要：以六盘水市为研究对象,构建交通可达性和区位优势度模型,借助ArcGIS 10.1软件,选取1990年、2000年、2010年、2016年4个截面,分析六盘水市90个城镇节点公路交通网络可达性、区位优势度的演化特征.结果表明:①公路交通网络发展历经了规划准备阶段—初步建设阶段—快速发展阶段—路网高等化发展阶段4个阶段,公路交通网络规模不断扩大,区内公路交通网等级结构日趋完善.②交通可达性显著提高,可达性时空离散程度表现出聚集—均衡—聚集的发展过程,其空间格局整体上呈现从南北廊道向东同心圆拓展态势.③交通区位优势度表现出聚集向均衡性发展态势,总体空间格局呈现出多中心圈层—中心圈层与轴线并行—轴线延展—短时圈连片发展阶段性演化特征.In this paper,Liupanshui has been chosen as the research object.With the help of ArcGIS10.1 software,the model of traffic accessibility and location advantage has been constructed,four sections in 1990,2000,2010 and 2016 been chosen,and the evolution characteristics of road traffic network accessibility and location dominance been analyzed with 90 nodes in the city.The results show that,1)the development of road traffic network had experienced four stages:planning,preparation-preliminary construction-rapid development-highway network development,and rural road traffic network in Liupanshui was expanded,the grade structure of road traffic network in Liupanshui was becoming more and more perfect.2)the accessibility of urban and rural traffic in Liupanshui had been significantly improved.The degree of spatial and temporal dispersion of accessibility shows the development process of agglomeration-equilibrium-agglomeration,and its spatial pattern as a whole presents the trend of concentric circle expansion from the North-South Corridor to the east.3)the distribution of urban-rural traffic location dominance in Liupanshui City showed a gradual development trend from aggregation to equilibrium.The spatial pattern of overall location dominance showed a phased evolutionary feature of“multi-center circle layer-parallel of central circle layer and axis-extension of axis-short-term circle development”.
