史載戰國扞關雖位於趙、楚兩國，不過，趙扞關並非真正關名，乃借指他關。楚扞關依時間先後，防禦對象的不同，先後設置於兩地。先在楚肅王四年（377B.C.）為防蜀國而置，簡稱拒蜀扞關（今四川省奉節縣東長江北岸）；爾後在楚懷王十八年（311B.C.）再次因拒秦國需要而另置，簡稱拒秦扞關（今湖北省長陽縣西清江北岸）。後人針對拒蜀與拒秦扞關位置是否相同，有一處與二處說之辨。本文討論的重點有三：（一）考辨扞關的地理位置，（二）闡述拒蜀扞關的名稱沿革與時代意義，（三）復原扞關所管控的交通路線圖。期能作為南方關隘研究的起步之一。

According to the history records, Warring States Han Pass was located in
Zhao and Chu countries, but the Zhao Han Pass wasn’t its real name. According to the time and the different targets it defended, the Chu Han Pass was constructed in two country. Firstly, constructed to resist the Shu country in Chu Suwang four years (377B.C.) was called Resist Shu Han Pass (Yangtze River north shore in Fengjie east of Sichuan). Later, constructed to resist Qin country in another place in Chu Huaiwang eighteen years (311B.C.) was called Resist Qin Han Pass (Qingjiangnorth shore in Changyang west of Hubei Province). However, there is an argument that if the two pass above all are in the same place. Hoping to start first step about the research of pass in south area, this article mainly discuss about three themes. Firstly, clarify the position of Han Pass. Secondly, explain the name and history of Resisting Shu Han Pass. Finally, make the transportation surrounding the Han Pass reappear.
