论汉晋至唐宋间大巴山地区的北向交通

On the Northbound Traffic of Daba Mountain Area from Han and Jin Dynasties to Tang and Song Dynasties

先秦大巴山地区的交通基本上以东线为主,此后,随着秦对汉中郡的重置,政治重心开始西迁的同时,交通重心也随之发生变化,在魏晋至唐宋形成了以南郑为辐凑中心的大巴山交通网络。魏晋至南宋,随着益梁地区南北争夺的激烈,大巴山地区交通渐趋繁荣,洋巴道、米仓道在这一时期巴山南北的军事、政治、商旅中发挥着异乎寻常的作用。中国古代大巴山地区的交通中军事因素始终是主导因素,其交通体系的变迁受制于军事战争的影响很大,这在汉晋三国及宋蒙战争中表现得尤其明显。

The traffic in the pre-Qin period Daba Mountain area was basically dominated by the east line.Since then,with the relocation of Hanzhong（ 南 郑） County of Qin dynasty,the political center of gravity began to move westward while the traffic center of gravity also changed. From Wei-Jin to Tang and Song Dynasties,Nanzheng county of Bashan convergence center for the traffic network. From Wei and Jin Dynasties to the Southern Song Dynasty,with the fierce competition between North and South in the Yi-Liang（ 益梁） area,the traffic in Daba Mountain is getting more and more prosperous. Yangba Road（ 洋巴道） and Michang Road（ 米仓道） play an extraordinary role in the military,political and business travels in north-south Bashan during this period. The military factors of traffic in the ancient Chinese Daba Mountain are always the dominant factors. The change of traffic system is greatly influenced by the military war,which is especially evident in the Han and Jin Dynasties and Three Kingdoms period and the Song-Mongol Wars.
