摘　　要：通过磁化率和地球化学元素的因子分析法和比值法分析提取出尉迟寺遗址地层记录的环境演变信息。本区5050aBP以前的新石器时期为暖湿的气候环境;大汶口文化阶段气候总体偏干冷,存在数次波动;从大汶口至龙山文化期间,本区气候发生了较为明显的变化,由干冷转向温湿,这为水稻生产提供了有利条件,也促进了龙山文化的繁荣。在5050aBP之前及4620aBP、4700aBP前后可能都发生过冷干事件。Environmental evolution information was extracted from strata of the Yuchisi Neolithic site based on principal component analysis of magnetic susceptibility and elemental geochemistry data. The climate in this area was warm and wet during the Neolithic period before 5050aBP. During the period of Dawenkou culture, the climate was drier and colder with mutiple fluctuations. From the Dawenkou to Longshan culture period, the climate returned to be warmer and wetter, which was conductive to rice production and accelerated the prosperity of the Longshan culture. In addition, cold and dry intervals may have occurred around 5 050aBP, 4 700aBP and before 4 600aBP.
