摘要: 运用因子分析法分析了临沂商品城沉积剖面特征微量地球化学元素及其比值,揭示了沂河中游末次冰消期至中全新世的气候演变过程.结果表明,沂河中游末次冰消期至中全新世沂河中游气候演变经历了6个阶段:(1)16866—13630 cal a B.P. 末次冰消期气候冷干;(2) 13630—10440 cal a B.P.气候回升但在11868—10440 cal a B.P.,气候突然变得冷干,基本上可以与YD气候事件相对应;(3) 10440—8672 cal a B.P. 进入全新世后气候以冷湿为主;(4) 8672—6755 cal a B.P. 大暖期气候不稳定波动剧烈,气候干湿交替,以暖湿为主;(5)6755—5850 cal a B.P.气候趋向干旱化;(6) 5850—4698 cal a B.P.气候转向暖湿.

Abstract: The typical section of Commodity Market was chosen to study the environmental changes of Yihe midstream. Based on the analyses of trace elements of Commodity Market Section, the paper can gain the climatic significance of trace elements. The results show that the environmental changes could be divided into six periods: 1) cold and dry period of 16866—13630 cal a B.P.; 2) colder and dryer period of 13630—10440 cal a B.P. include Younger Dryas Envent; 3) cold and moist period of 10440—8672 cal a B.P.; 4) warm and moist fluctuated period of 8672—6755 cal a B.P.; 5) warm and dry period of 6755—5850 cal a B.P.; 6) warm and moist period of 5850—4698 cal a B.P.
