《三国志·明帝纪》“为汝阴郡”校勘平议——兼谈曹魏汝阴郡的辖县名目

Discussion on Proofreading of"Wei Ruyin County"in the Records of the Three Kingdoms of the Ming Emperor——The Item of Counties in the Jurisdiction of Ruyin County in the Wei State

《三国志·明帝纪》“为汝阴郡”中的“为”字属于衍文性质,“汝阴郡”乃宋县的上属郡。曹魏时期新置的汝阴郡由汝南郡析置,辖域范围以汝南郡东南部颍水流域为中心,同时兼取汝水下游部分区域。这样的区划不仅在地域上易于分割,同时也体现了魏晋之间政区的连续性。汝阴郡拥有汝南郡东南部除城父、山桑县外的全部辖境,至少领有十四个县级政区。

The character"wei"in the records of"Wei Ruyin County"of the Three Kingdoms of the Ming Emperor belongs to the feature of the derived text,and Ruyin County is a superior county of Song County.The newly established Ruyin County during the Wei state of the Three-Kingdoms Period was separated from Runan County,with its jurisdiction centered around the Yingshui River Basin in the southeast of Runan County,which also includes part of the downstream of the Rushui River.This administrative division does not only make it easy to divide geographically,but also reflects the continuity of political regions between the Wei and Jin dynasties.Ruyin County has all the jurisdiction in the southeast of Runan County,except for Chengfu and Shansang County,which has at least fourteen county-level administrative districts.
