摘　　要：针对通道所连接的区域之间的关联度随距离的延长而逐渐弱化的特点,从系统的整体与局部关系出发,提出了广域运输通道的分割理论.分析了区域关联度计算的复杂性.区域关联度计算的基础是OD表,OD对间的客货流量代表了区域间关联关系的强弱.建立了基于OD表的通道分割方法,并探讨了通道分割时OD表的应用.用大西南通道分割的实例验证了方法的可行性.A theory for division of transportation corridor in a WAN （ wide area network） was proposed based on the relationship between the whole and a part of the network, and the characteristic that the correlation degree between two regions connected by the corridor decreases as the distance between them increases. Calculation complexity of correlation degree was analyzed. A correlation degree between two regions is calculated from OD （origin to destination） tables, and is represented by the OD flows of passengers and cargo. A method for division of a corridor based on OD tables was presented, and the procedure of application of OD tables was discussed. The feasibility of the proposed method was verified by division of the southwest corridor in China.
