摘要
分析了半干旱的甘青地区全新世中期环境变化序列与史前文化发展序列,探讨了环境变化对史前文化发展的影响。分析发现;研究区中全新世优越的环境条件,为史前文化发展提供了更大的回旋空间,有利于古文化的繁荣;当环境变化的幅度超过了社会的承受力阀值时,就会导致史前文化的断层或转型;4 ka BP以后气候的凉干化,是该区文化面貌衰退、牧业因素增加的主要原因。
Through analysis of the environmental change and cultural evolution of Gansu-Qinghai region in mid-
dle Holocene,the impact of environmental change on the prehistoric culture is discuised. The culture evolution is closely related to environmental change. When the climate became warm, wet and less unstable, the prehistoric culture developed rapidly. If the rapid environmental change was so great that human society couldn't stand it any longer,the prehistoric culture halted or fell into another pattern. After 5000 a BP.the cool and dry trend played a prominent role in the declining process of the prehistoric culture. However, the relationship between the environmental change and cultural evolution is very complicated, there are many questions remain unanswered. How to understand the relationship at high temporal resolution is one of the most important questions.
