树木年轮在青海西部地区吐谷浑与吐蕃墓葬研究中的应用

The Application of Dendrochronology in the Research of Tuyuhun and Tubo Tombs in Western Qinghai Area

本文以树木年轮的定年结果为依据,将近年来都兰热水、德令哈等地所发现和发掘的一批墓葬分为吐谷浑时期和吐蕃时期,根据墓葬形制的渊源关系并结合文献资料对墓葬的族属进行了分析,认为封土堆中有无梯形石砌边框是区分海西地区吐蕃时期外来吐蕃人与被征服的吐谷浑人墓葬的重要标志。由此推断都兰热水墓主人的主体应属于外来吐蕃人,而德令哈一带吐蕃时期的墓主人主体属于被征服后的吐谷浑人。

Based on the dating results by dendrochronology, the author divides the tombs excavated at Reshui in Dulan and Delingha in recent years into Tuyuhun stage and Tube stage. After analyzing the tombs＇ nationalities by the origin relationship through the tombs＇ styles and historical data, the author believes that whether there is a trapezoid frame build by stones in the earth-mound of the tomb is a key symbol in distinguishing extraneous Tube people from the conquered Tuyuhun people in Western Qinghai aera. It could be concluded that the main body of tombs＇ occupants from Dulan Reshui belong to Tube people and Delingha＇s are the conquered Tuyuhun people.
