摘　　要：目的研究交通发展是区域城镇体系形成、发展的重要影响因素。方法运用引力模型,计算、分析了交通因素对陕西省城镇体系的影响。结果陕西省各城市间吸引力大幅度提升,尤其是西安市对其余地级市的辐射。结论①交通的发展对城市之间相互作用力的提升和经济增长具有明显的推进作用;②交通对不同等级规模城市的产业结构具有不同的影响,表现为第二产业在中心城市中的比重逐渐下降,第三产业比重相对上升,同时第二产业沿交通线向次中心城市转移,毗邻中心城市的次中心城市第三产业受中心城市的影响有所下降;③交通改变了区域城镇体系的空间结构,推动了城市群的出现和发展,进而带动了区域整体上的经济发展。Aim To study traffic development which is an important influencing factor to form and develop the regional urban system. Methods The gravitation model is used to calculate and analyse traffic factors to influence the regional urban system of Shaanxi Province. Results The attractiveness of cities in Shaanxi Province steadily grow,especially the city of Xi＇an has exerted radiation effects on other prefecture-level cities. Conclusion ① Traffic development obviously promote the interaction force among cities as well as economic development of cities.② Traffic has different impact on industrial structure in different class and different scale cities.In particular,the proportion of the secondary industries drops gradually,while the proportion of the tertiary industry rises relatively.③ Traffic can not only change the space structure of regional urban system but also stimulate the emergence and development of groups of cities and accelerate the development of the regional economy.
