六胡州古城址的发现及其环境意义

本文在追溯唐代六胡州的建置与“灵、夏之间”行政沿革的基础上,通过对内蒙古、宁夏、陕西三省区交界处,即毛乌素沙地西南缘的实地考察,并依据考古与文献资料,初步确定了今鄂托克前旗与盐池县境内的六个唐代古城址与六胡州的对应关系。从古城址的时空分布格局、选址条件、人类活动方式等出发,阐述了六胡州古城址的环境指示意义。唐初六胡州北部已经有比较严重的土地沙漠化问题,而六胡州一带建城时因受早期沙漠化过程的影响,在局部地形部位可能分布有地表积沙。

Discovery of Liuhu State Relic and Its Significance of Environmental Indication

Based on large numbers of archeological evidence and historic documents, this paper first explained how “Liuhu State (six barbarians’ habitation)” was formed and transformed. Then, combined with the field work at the adjoining area of inter Mongolia Municipality, Ningxia Hui Municipality and Shan xi province located at the south-west Mao Us Desert, the author found that there were six abandoned castles (Xingwu Camp, Balang Temple, Ao Le Zhao Qi, Wu Lan Dao Beng, Cha Gan Ba La Gasu and Ba Yan Hu Ri Hu ) built in Tang Dynasty and they were well corresponding to Liuhu State document records( Xingwu Ying to Luzhou, Others need more work ). At last, this paper discussed some environmental indication of these abandoned castles by analyzing their time-space distribution, environmental condition and possible human activities around. The results were: (1) since from Han dynasty, there were at least three desertification processes occurred in the Mao Us Desert; (2) during South and North Dynasty,and at end of Tang and the Five Dynasty,there existed severe desertification problem in the Mao Us Desert, (3) when first set up Liuhu State, there had been partial areas covered with sand dune.
