摘　　要：为实现交通运输资源的合理配置,在区域综合运输网络下,研究公路、铁路、水路和航空等4种货运交通方式的优势运输距离范围（以下简称优势运距）,提出基于分担率函数的优势运距量化分析方法.首先界定了货运方式绝对优势运距和相对优势运距内涵;其次,以货运方式分担率分析为基础,分别构建了各货运方式的绝对运距模型与相对优势运距模型;最后,进行实证分析.结果表明,在50～3 000 km运距范围内,航空货运不具备绝对优势运距,公路、铁路、水路货运方式绝对优势运距分别是50～477、477～1 168、1 168～3 000 km;而公路、铁路、水路、航空货运方式的相对优势运距分别为50～303、526～1 004、2 410～3 000、1 681～2 283 km.A new quantitative analysis method of dominant transportation distance based on mode split rate is developed to compute the dominant transportation distance in the integrated transportation system that include the highway, railway, waterway, and airway, which can contribute to the rational allocation of transport resources. First of all, the absolute and relative dominant transportation distance of freight transportation modes are defined. Then, the absolute and relative dominant transportation distance models of each freight transportation mode are established on the base of mode split rate. Finally, a case study of proposed method is carried out, the result of which indicated that the absolute dominant transportation distance ranges of highway, railway and waterway are 50～477 km, 477～1 168 km and 1 168～3 000 km, while the airway did not have an absolute dominant transportation distance in this range. The relative dominant transportation distance range of highway, railway, waterway and airway are 50～303 km, 526～1 004 km,2 410～3 000 km, and 1 681～2 283 km.
