摘要
研究表明晚全新世柴达木盆地气候进一步向干旱化方向发展,气候的干旱化以及由此导致的环境变化对盆地古文化产生了深刻的影响,全新世气候与环境的变化深刻地影响着柴达木盆地古人类文化的出现、发展与衰亡。地层剖面测年与分析表明,柴达木盆地诺木洪文化兴盛于约3300aB.P.,衰亡于约2900aB.P.,诺木洪文化在这发展过程中受气候波动的影响曾出现一次文化断层,由此可将诺木洪文化分为前后两期。环境变化是柴达木盆地史前古人类文明兴衰重要决定因素。
In Qaidam Basin, widespread of desert and loess record information about environmental evolution. Accompanied by abundant ancient cultural relics, all these make it a proper region for the study of the relationship between human adaptation and paleoenvironmental change. The Talitaliha section, located in the southeastern margin of Qaidam Basin, is ideal place for further investigation on Holoeene climatic variations and their impact on human activity. Both field observations and analytical results confirm the abrupt environmental change at 3 eal, ka B, P, The results indicated that Nuomuhong culture in Qaidam Basin was developed in about 3300aB. P. and ceased about 2900aB. P. During the period of ancient culture development there was an interruption. Therefore, Nuomuhong culture can be divided into two periods. According to the process of human culture development and environmental evolution in Qaidam Basin, the prosperity and disappearance of the ancient human culture were correlated with environmental changes, especially drought and desertification.
