| 摘 要： | 临沂商品城剖面记录了末次冰消期至中全新世沂河中游的气候环境变化,其地球化学元素的古环境意义显著。分析表明末次冰消期至中全新世沂河中游的古气候环境经历了5个阶段:(1)16866～13630cal a B.P.气候回暖但仍以冷湿为主;(2)13630～10440cal a B.P.气候变冷变干,并记录到了YD气候事件;(3)10440～8670cal a B.P.暖湿气候显著;(4)8670～6420cal a B.P.冷暖波动仍以暖湿为主;(5)6420～4698cal a B.P.稳定的暖干气候环境。

| Abstract: | The typical profile of a Commodity Market was chosen to study the environmental changes of the Yihe River midstream.Based on the analyses of geochemical elements of the Commodity Market profile,this study can gain the environmental significance of geochemical elements.The results showed that the environmental changes involved five periods: the cool and moist period of 16866~13630 cal a B.P.;the cool and dry period of 13630~10440 cal a B.P.including the Younger Dryas Event;the warm and moist period of 10440~8670 cal a B.P.;the cool and warm fluctuated period of 8670~6420 cal a B.P.;and the warm and dry period of 6420~4698 cal a B.P.,which respond to global changes well. |
