摘要
敦煌自古便是中西文明交往要地。汉武帝经略河西,设四郡,敦煌郡最西,辖六县,是扼控西域的战略要地。长期以来,汉敦煌六县的位置探讨是敦煌史地研究的重要组成,但对部分城址位置的争议未有断绝。结合文献记载和野外考察分析,对几个确定城址选址的环境特点进行了综合分析,发现相应城址的选址存在以河流为依托且位于山前冲积扇缘与绿洲交接地带的规律。存在这一规律的原因在于冲积扇缘地带农业生产条件好,且一般位于交通线路附近,在可开垦土地广袤的情况下,这一地带对首次入主河西的中原农业民族来说开垦条件最为适宜。这一规律为干旱区绿洲城镇的选址研究提供了一个新的视角,并指示目前争论较多的渊泉县址宜在旱湖脑古城位置,而不是早先学者认为的四道沟古城。
Since ancient times,Dunhuang has been a chokepoint of communication between Chinese and west-ern civilizations.Emperor Wu of Han Dynasty set up four counties to control the Hexi Region,and Dunhuang Prefecture was located in the west,with six counties under its jurisdiction,which was a strategic place to control the Western Regions.The location of the six counties has long been an important component of Dunhuang's his-torical research,but the location of some of the city sites is still controversial.This paper presents a comprehen-sive analysis of the environmental characteristics of several identified city sites,combining documentary and fieldwork analyses.The results show that there is a pattern that the sites are river-based and located at the intersec-tion of mountainous alluvial fan margins and oases.The reason of this pattern is that the alluvial fan margin zone has good conditions for agricultural production,and is generally located near transportation routes,so given the vastness of the land that can be reclaimed,this zone is the most suitable for the agricultural peoples of the Cen-tral Plains,who is the first to dominate the Hexi Region,to reclaim.This pattern provides a new perspective for the study of the location of oasis towns in the arid zone,and indicates that the currently debated site of Yuanquan County should be in the location of the ancient city of Hanhunao,rather than the ancient city of Sidaogou as earli-er thought by scholars.
