摘　　要：运用引力模型,在提出"引力度"概念的基础上,计算了关中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.具体表现为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;高速公路发展对不同等级规模城市产业结构产生不同影响,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;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.By using the gravitation model, this paper analyzed the intimacy influences of the guest and the flow of goods quantity which have a great effect on the development of urban system between the urban systems of Guanzhong Area 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 different in rank scale, especially the directs dynamics become much stronger in the key city and secondary center city, the influences of highways on the secondary industry of key city and the third industry of secondary center city are much bigger; （3）After opening the highway traffic, the impact of traffic factors on the movement concentrated to the urban, and emergence and the development of of population has decreased, the town and rural population has e spatial distribution of population has changed, which accelerate the urban agglomeration.
