摘要

摘要: 运用古气候参数方法对四川洪雅GMH剖面进行孢粉分析,结合定年数据,分析出本区自晚更新世晚期以来的植被变化和气候变化并与我国南方石笋记录等进行对比分析。研究表明:从大约35670 aBP以来,四川洪雅地区总体经历了暖湿—温润—凉干—温润—冷干—温湿—凉润—暖湿—温润的气候变化过程,其间多有反复;GMH剖面孢粉记录与我国南方石笋记录在古气候变化的大趋势上基本一致,对H3、H2、H1、YD等气候事件反映明显;E带(21100-17000 aBP)对应的降温减湿期较石笋记录提前出现与研究区位于第一、二级阶梯过渡地带、山前台地的地貌特征有关;对比发现I带中的温干气候期(约2150aBP前后)具有一定的区域性意义。

Abstract: Sporopollen analysis on the GMH section in Hongya County, Sichuan Province is done by means of paleo-climate parameter methods and changes in paleo-vegetation and paleo-climate during later period of the late Pleistocene is reconstructed in combining with dating figures in the paper. Furthermore, comparative analysis with the stalagmite record from South China is done. The results show that: the process of paleo-climate change in Hongya is warm and wet - moderate and moist - cool and dry - moderate and moist - cold and dry-moderate and moist - cool and moist - warm and wet - moderate and moist from about 35670 a BP and there are some reversals in the process; GMH sporopollen record shows nearly same trend of paleo-climate change in contrast with the stalagmite record in Dongge Cave and Hulu Cave, and the climate events including H3, H2, H1, YD appeared in the pollen record obviously; the colder and drier process in E-zone(21100 – 17000 a BP) occurred earlier than the stalagmite record, it is due to the landform characteristics in the research area that locates in the transition zone from Tibetan Plateau to Szechwan Basin and the section is in a platform front of the E-mei mountain; the moderate and dry period in I-zone (about 2150 a BP) has certain regional significance.
