摘　　要：以长株潭城市群中的12个节点城市为研究对象,以连接长沙、株洲和湘潭的主要高速路或高等级公路为运输通道,构造了"两横三纵"的运输通道网。通过运输通道场理论计算并对比了2005年与2012年"两横三纵"运输通道网内12个节点城市经济发展因子、聚散规模量因子、聚散规模质因子、广义运输成本、场势和场势差,探索分析交通对区域经济的作用和影响。结果表明:1道路交通的改善能够促进区域经济的发展,表现为缩短运输通道距离和降低城市广义运输成本。2城市势能高低反映区域辐射力强弱,势能高则辐射力强,对周边区域的带动作用越强,反之则相反。3城市势能差所产生的集聚与扩散效应与城市发展阶段有着紧密联系,表现为发展中的地区以集聚效应为主,吸纳优势资源促进自身发展;较发达地区以扩散效应为主,以辐射带动周边区域促进共同繁荣。take the 12 node cities in Changsha- Zhuzhou-Xiangtan Urban Agglomeration as the research objects, take the main highway or high grade motorway as the transportation corridors, we built a＂two horizontal three longitudinal＂transportation corridor network. Through transportation corridor field theory, we calculated and compared the economic development factor, the accumulation and diffusion scale factor, the accumulation and diffusion quality factor, the general transportation costs, potential energy and field potential energy difference of the 12 node cities within the＂two horizontal three longitudinal＂transportation corridor network in 2005 and 2012, studied the role and impact of transportation on the regional economy. The results showed that：（1） the improvement of road traffic can promote the development of regional economy, characterized by shortening the distance between transportation corridor and reduce the urban general transportation costs.（2） the level of urban potential energy reflects the regional radiation strength. The higher potential energy, the stronger radiation power, and the stronger leading role on surrounding area, and vice versa.（3） urban accumulation and diffusion effect generated by potential energy difference is closely connected with urban development stage. The developing regions are mainly characterized with accumulation effect, absorb the advantages of resources to promote its own development; the more developed regions are mainly characterized with diffusion effect, radiate and drive the surrounding area to promote the common prosperity.
