陇西黄土高原新石器文化与环境演变的可能联系

本文运用黄土－古土壤磁化率记录、＾１４Ｃ测年以及孢粉组合分析测试手段，研究了该地区全新世以来自然环境的演化（着重古气候的演化过程），揭示了全新世气候存在五个相对温暖湿润的古土壤发育阶段和五个相对干燥寒冷的粉尘堆积阶段。同时结合考古资料，探讨了环境变化与人类文化的产生、迁移、发展之间的可靠联系，指出古气候的变化是文化类型发生转变的重要原因之一。

The Probable Relationship between Environmental Change and Neolithic Chltute in Loess Plateau of Longxi

By using the methods of Loess-fossil siol magnetic susceptibility,C-14 dat-ing and palynologic analyses,this paper studies the natural environmental changes(es-pecially the process of palaeoclimatic variation)in the Longxi area since Holocene.Theresult suggests that there are five stages of development which were characterized byrelative warmth and moisture and in which palaeosols were formed and there we otherfive stages manlced by cold and drougyt in which silts were deposited.Based on Thesearchaeological data,this paper also discusses the probable relationship between environ-mental changes and the generation and development of human culture.It is pointed outthat the palacoclimatic variation was one of the most important factors deciding thechange of culture type.
