中文摘要：

北朝时期＂河曲＂地域的行政区划经历复杂的演变。北魏统治下的＂河曲＂行政区划建制可分成两个阶段：军镇制阶段和州郡县阶段,遭逢六镇动乱之际,改置州、郡、县之数较少。西魏、北周时段,＂河曲＂地域行政建制单位较前陆续增加,并增建高级管理实体———总管府,构成地方行政区划的四个层级,分布范围较前扩大,呈现自南向北推广之势。隋朝初期8年间,在继承北周的四级行政体制基础上,更在阴山南麓的河套平原增置总管府及州县等行政建制单位。北朝时期＂河曲＂地域行政区划的演替进程呈现出由最初的军管体制向州郡县体制转变,而且正规州郡县行政单位数量逐渐增多、分布范围越来越广的时空特征与发展态势。

英文摘要：

The administrative division of the ＂Hequ＂ region went through a complicated change in times of the Northern Dynasties.The system of administrative division of the region under the rule of the North Wei Dynasty could be divided into two stages,the stage of military governorship and the stage of state-country division.Even in time of the Six-military-governor Rebellion,only a few areas were imposed into state-county system.In the period of the West Wei and the North Zhou Dynasty,regular administrative subdivisions in the ＂Hequ＂ region increased continuously and the government of general administration,a summit administrative organ,was introduced,forming four distribution-extended hierarchies of local administrative division extending from south to north.In the early eight years of the Sui Dynasty,in addition to carrying on the four-hierarchy administrative system established in the North Zhou Dynasty,the court added the governor-general government and administrative subdivisions of state and county in the Hetao Plains at the southern foot of the Yin Mountains.To sum up,the process of change of administrative division in the ＂Hequ＂ region showed a time-space feature of a gradual increase in the number of regular administrative subdivisions,such as state and counties,and a continuous expansion in the range of distribution.
