Abstract: The ZLTC (Zhongliangtiechang) profile lies outside the north wall of Taosi Site in Linfen Basin, Shanxi, China. Based on systematic measurement and analysis of grain size, magnetic susceptibility, Rb/Sr ratio and CaCO₃, and combining the optically stimulated luminescence (OSL) ages and the archaeological data, the authors investigate the regional environment change during the Holocene and the relationship between environment and human activities. The results show that, during the early Holocene (10.5 to 9.6 kaBP), the East Asian winter monsoon intensity is weak, and the intensity of weathering and pedogenesis enhances remarkably, thus the climate turns from cool-dry to warm-wet; during the early-middle Holocene (9.6 to 4.9 kaBP), the intensity of weathering and pedogenesis is at its maximum in the profile, thus the climate is warm-wet; during the middle-late Holocene (4.9 to 2.5 kaBP), the intensity of weathering and pedogenesis diminishes gradually, thus the climate turns to warm-dry; during the late Holocene (2.5 kaBP to present), the East Asian winter monsoon intensity is strong, the intensity of weathering and pedogenesis is weak, thus the climate turns to cool-dry. The warm-wet climate correlates well with the development of culture, while the vegetation degradation could be influenced by climate and human activities in cool-dry period.

摘要： 在对临汾盆地陶寺遗址北城墙外全新世黄土剖面粒度、磁化率、Rb/Sr值和CaCO₃含量等气候指标进行分析的基础上, 结合光释光测年结果和考古学资料, 探讨该剖面记录的环境信息及其与文化发展的相互关系。研究发现: 全新世早期(10.5~9.6 kaBP), 东亚冬季风较弱, 风化成壤作用增强, 气候由凉干转向暖湿; 全新世早中期(9.6~4.9 kaBP), 风化成壤作用最强, 气候最为暖湿; 全新世中后期(4.9~2.5 kaBP), 风化成壤作用较之前有所下降, 气候较之前温干, 但较现今暖湿; 全新世晚期(2.5 kaBP)以来, 东亚冬季风增强, 风化成壤作用较弱, 气候较为凉干。暖湿气候期与文化的繁荣发展时期有较好的对应关系, 凉干气候期植被的退化可能受气候和人类活动共同作用的影响。
