中文摘要：

以唐代李贤《后汉书》注中引用《水经注》的47条资料为考察对象,研究了北魏郦道元的《水经注》在唐初的大致面貌。认为唐初的《水经注》是经、注分开的,李贤等人所见到的《水经注》与今本《水经注》有完全相同的文字;也有今本所亡佚的文字,将李贤等人所见到的《水经注》与今本《水经注》相互比勘,可以订正各自的错讹;两种版本的《水经注》,都有重要的文献价值。

英文摘要：

The article takes as the study object the forty-seven data of the notes of Commentary on the Waterways Classic（ Shui Jing Zhu） in History of the Later Han Dynasty（ Hou Han Shu） by Li-xian in the Tang Dynasty so as to have a restricted view of the general features of the early Tang Dynasty.The study shows that jing was separated from zhu in Commentary on the Waterways Classic in the early Tang Dynasty; the Commentary on the Waterways Classic seen by Li Xian et al has exactly the same words as the current version of Commentary on the Waterways Classic,and some words in the old version have disappeared in the current version.A comparison of the two versions helps to correct their errors and is of great value in literature.
