| 摘 要： | 青海东北部自然环境对全球变化响应敏感,且本区史前文化发达、序列完整、遗迹丰富.因此本区是我国研究气候变化对史前文化影响的典型区域.利用气候和考古研究结果,采用GIS和数学分析方法,发现：4 kaBP本区气候向干冷化突变,齐家文化在3.9 kaBP突然衰弱,在干冷形势基本稳定的3.6 kaBP,出现辛店文化和卡约文化,遗址数猛增;齐家文化是农耕文化,辛店文化继承了齐家文化的生产活动,其地域范围缩小,向低海拔和向东部的低山丘陵、河谷、沟谷地带退缩;而卡约文化在适应气候突变后,改变了原有的生产方式,产生了一种新的经济方式--畜牧业,并向西和更高海拔的中山地、高山地等扩展,地域范围达到史前文化最大.因此气候突变,史前居民采取了不同的应对策略,进而形成不同的文化,气候突变是本区史前文化由单一向多元分异的重要驱动力,也是本区大型聚落难以维系,文明进程受挫的重要原因. |

| Abstract: | The natural environment of the northeastern part of Qinghai province has close relation to global climate changes. In this region there are highly developed prehistoric culture, complete sequences and plentiful vestiges. So it is the typical area where the research of the impact of climatic change on the prehistoric culture of China can be conducted. By researching the regional climate and archeology with the methods of GIS and mathematics analysis, we can find that the climate tended to be dryer and colder at 4 kaBP, so, the Qijia culture dramatically became declined at 3.9 kaBP; the climate kept a dry and cold situation at 3.6 kaBP, which promoted the appearance of the Xindian and Kayue cultures and the increase of a lot of relics; the Qijia culture belongs to a farming culture, the Xindian culture inherited the productive activity from the Qijia culture with its regional scope changing smaller to low sea-level, low mountain and river valley areas; but the Kayue culture changed its own productive pattern and produced a new economic way-animal husbandry after the abrupt climate changes, and its regional scope became the largest in prehistoric culture age. Pre-historic residents took different measures due to the abrupt climate changes, then different cultures developed. Climate change is a major driving force that made prehistoric cultures diversified. It is also one of the most important reasons why large selttlements cannot be maintained for a long time and civilization process suffered setbacks. |
