论汉藏人文地理分界线——以河洮岷地区为中心的分析

Study on the dividing line of Han/Tibetan human geography:Based on the analysis of the Hetaomin area

历史时期汉藏人文地理分界线在青藏高原东北缘曾有三次较大的变动。文章论述了三次汉藏人文地理分界线的形成、摆动与稳定及其环境意义。认为,雪山(祁连山)—黄河分界线是唐蕃依据地理条件最有利原则下的一种势力范围划分;六盘山—陇山分界线是地理条件决定下的唐蕃分界线;唐蕃以后汉藏人文地理分界线的缓慢西移并最终稳定在河洮岷一线,汉藏民族的经济理性行为是其重要的影响因素。

The dividing line of Han/Tibetan human geography in history has changed three times on the edge of northeast Tibetan Plateau. The article discusses the becomings, changes, stabilization and its environmental significance of the dividing line of Han/Tibetan human geography. It concludes three points. First, the dividing line of Qilian Mountains--Yellow River divided the influence sphere between Tang Dynasty and Tubo Kingdom according to the most favorable geography conditions prin- ciple. Second, the line of Liupan Mountain--Long Mountain, as a dividing line of Tang and Tubo, was decided by the geography environment conditions. Third, the dividing line of Han/Tibetan human geography moved westward slowly after Tang Dynasty and finally located along the line of Hetaomin, which was closely related to the Han/Tibetan nationalities＇ economic exchanges.
