摘要: 统万城筑城环境背景是认识毛乌素沙地北魏时期环境的关键所在。基于野外观察,结合历史文献、考古发现和已有研究成果对此问题进行了深入分析,其中建城时周边的水环境和沙漠化程度是研究的重点。研究结果表明,统万城建城时水环境远好于现在,在统万城东北和西北存在多个湖泊,但单个湖泊面积不大。建城时有可能从西北查干圪台处的湖泊引水至统万城附近,并在沿途人工挖掘形成季节性的小湖。根据现今沙漠化程度划分标准,建城时周边的沙漠化程度属于轻度,局部为中度。本研究提供了认识统万城建城环境的新途径,在明确毛乌素沙地历史环境变化机制中有重要意义。

Abstract: Knowing the environmental background of building the Tongwan City is critical to understand the environmental characteristics of the Mu Us Sandy Land in the North-Wei Dynasty. Combining historical records, archaeological findings, previous research literatures with extensive field work, we try to restudy the environmental background of building the Tongwan City, focusing on the water environment and desertification degree. Results show that: (1) There were several lakes at the northeast and northwest of the Tongwan City when it was built, but the area of these lakes was small. Some of the lakes at the northwest of the Tongwan City might be artificially made. (2) The desertification degree around the Tongwan City was generally light in the North-Wei Dynasty, and on partial area the degree was moderate. This research has important significance for understanding the historical environment of the Mu US Sandy Land.

Key words: the Mu US Sandy Land, Tongwan city, desertification degree, river, lake
