云南昆明盆地中更新世晚期以来的孢粉记录及古气候演化
|
摘要
通过"昆明市活断层探测与地震危险性评价"项目获得了昆明盆地的东西两侧各一个钻孔的孢粉资料和测年数据,对比分析了昆明盆地自中更新世晚期以来的植被演替和古气候演化。研究表明,沉积环境对孢粉记录有重要的影响作用。近200 ka BP以来,昆明盆地总体经历了温凉偏干(201~180 ka BP)—温和偏干(180~132 ka BP)—温暖偏干(132~89 ka BP)—温和偏湿(89~75 ka BP)—温暖湿润(75~38 ka BP)—温凉偏湿(38~22ka BP)—温暖偏干(22~6 ka BP)的气候变化。从区域和全球对比上来看,昆明盆地与滇中和滇西地区的气候变化较为一致,同时又有自身的一些特点。
Pollen and age data have been collected in two cores from the Kunming basin by the project "Exploration of Active Fault and Evaluation of the Danger of the Seism in the Kunming Basin" to analyze the vegetational change and paleoclimate evolution from late Middle-Pleistocene in this area.The results show that sedimentary environment has an important role in the analysis of pollen records and the paleoclimate evolution of the Kunming basin from late Middle-Pleistocene: slightly cold and moderately dry(201~180 ka BP)-slightly warm and moderately dry(80~132 ka BP)-warm and moderately dry(132~89 ka BP) — slightly warm and moderately humid(89~75 ka BP)—warm and humid(75~38 ka BP) — slightly cold and moderately humid(38~22 ka BP)— warm and moderately dry(22~6 ka BP).Compared with the paleoclimate history of the Qinghai-Tibet Plateau and the global records,it is indicated that the paleoclimate evolution in the Kunming basin is in accordance with the paleoclimate in central and west of Yunnan province.
