摘　　要：研究高速公路是影响城市间引力度的重要交通因素。运用引力模型,在提出"引力度"概念的基础上,计算陕西省西安地区主要城市间引力度并分析了高速公路对城市发展的影响。结果表明:高速公路使城市流强度大大增强,城市之间的空间引力增大。1)高速公路对城市发展的影响与城市间引力度呈正相关上升趋势;2)高速公路发展对不同等级规模城市产业结构产生不同的影响,表现为中心城市与次中心城市引力度越大,对中心城市的第二产业与次中心城市的第三产业影响越大。3)高速公路开通使人口移动受交通因素影响减小,农村与城镇人口向城市集聚,改变了人口的空间分布,加速了城市群的出现、发展及城市化进程。We analyzed the intimacy influences of the highway on the flow of goods which have a great effect on the development of urban system of Xian on the base of proposing the concept of ＂directs dynamics＂. The results indicate ： 1 ） There is a tendency of positive relation between the impact of highway on urban development and the attractions among cities. 2）The highways have different influences on the city industrial structure which is differ ent in rank scale, especially the directs dynamics become much stronger in the key city and secondary center cit y, the influences of third and secondary industry to key city and secondary center city ; 3 ） After opening the high way, the impact of traffic factors on the movement of population has decreased, the town and rural population has concentrated to the urban and the spatial distribution of population has changed, accelerating the emergence and the development of urban agglomeration.
