| 摘 要： | 通过对地形、综合地层剖面年代、遥感影像、历史地图和历史文献等的分析，深入探讨了无定河上游历史时期河湖水系的情况。现今无定河上游，即萨拉乌苏河上游山区的水源地为袭夺无定河的另外一条支流芦河而来，且袭夺发生在北魏以后，明代之前。袭夺之前，东西向湖泽湿地的存在，影响了该区历史人类活动的空间分布，主要表现在人类聚落选址、交通通道等。本研究为重新认识《水经注》中有关奢延水的记载提供了新的地理参照，有助于重建无定河上游的历史景观，同时为理解黄土地区的历史河流演化提供了典型案例，具有重要意义。

| Abstract: | The Wuding River is situated in the arid and semi-arid area of northern China, where the ecosystem is very sensitive. Historically, the region is a border region of central China and northern nomadic tribes. Therefore, its physical environment and the water resource would impact the location of human activities, such as transportation, town setting, and land reclamation and so on. Through topographic analysis, comprehensive stratigraphic profile dating, remote sensing images, historical maps and historical literature analysis, this paper discussed the situation of the river and lake system at its upper reaches of Wuding River in the historical period. We found that the water source of the upper reaches of Wuding River, that is, the upper reaches of Salawusu River, captured another tributary of the Wuding River, that is, the Lu River. The piracy took place after the Northern Wei Dynasty and before the Ming Dynasty. Before the piracy, the existence of the EW-trending Lake Wetland affected the spatial distribution of historical human activities in the area, mainly in the selection of human settlements, transportation channels and so on. This study provides a new geographical reference for re-recognizing the records in Shuijing Zhu, helps to rebuild the historical landscape of the upper reaches of Wuding River, and provides a typical case for understanding the evolution of historical rivers in the Loess Plateau, thus is of great significance. |
