由于《辽史》粗疏,而其本身文字量又小,资料不全,致其舛讹甚多,在我国古代“二十四史”中恐怕是最受指责的,为历来研究者所垢病。其中尤以《地理志》问题更多,这是治《辽史》者之共识。所以出现这些问题,究其原因,大概不外乎以下几点:一是《辽史》完成距辽亡时间过长,跨过整个金代,到元时才开始编纂,已是隔代,情况不够清楚明了,无法写得详尽;二是金灭辽时,战争残酷,斗争激烈,辽帝逃跑,材料损失,自不能免,而元灭金时,也是社会变动极大,情况同辽无甚差异,使资料档案又遭受一次损失,残缺不全,实难说清原委;三是《辽史》写作时间极短,仅一年时间 Due to the “Liao history” is coarse, and its own small amount of text, incomplete information, resulting in a large number of false positives, in ancient China, “Twenty-Four Horizons” is probably the most accused, for the historian of scale disease. Among them, the issue of “geography” is more, which is the consensus of those who rule the history of Liao. Therefore, the emergence of these problems, the reason is probably nothing more than the following: First, the “Liao history” completed from the Liao died too long, across the entire Jin Dynasty, only began to compile the Yuan Dynasty, has been the next generation, the situation Not clear enough, can not write exhaustive; the second is when the gold out of Liaoning, the war cruel, fierce fighting, Liaodong escape, material loss, can not be avoided, and the yuan off gold, but also social changes, the situation with Liao no Differences, so that the data file has suffered a loss, incomplete, difficult to tell the whole story; Third, “Liao history” writing time is extremely short, only one year
