| 摘 要： | 通过对山西芮城桃花涧剖面孢粉分析，结合沉积物的粒度特征和沉积物AMS 14C测年数据，探讨了中全新世晚期该区的古文化年代及古环境变化，为恢复其古环境面貌提供了可靠的定量数据。分析结果表明，该遗址文化层的年代为庙底沟文化时期。根据孢粉组合特征，可将剖面划分为3个孢粉带：5 250~5 000 aBP期间气候温和湿润，呈现出稀树草原的植被面貌；5 000~4 800 aBP期间气候温凉偏干，呈现出荒漠草原的植被景观；4 800 aBP之后气候温凉湿润，呈现出稀树草原的植被面貌；气候变化与邻区同期相吻合。

| Abstract: | Based on the analyses of sporo-pollen,grain size and accelerator mass spectrometric(AMS)14C dating data from Taohuajian profile in Ruicheng County,Shanxi Province,this paper discusses the ancient cultural date and the paleoenvironmental change since Late Mid-Holocene.The study provides reliable quantitative data for the reconstruction of paleoenvironment in this area.The result shows that the climate is accord with its neighbouring areas,and the ancient cultural date belongs to the period of Miaodigou cultu... |
