摘要
利用14C测年及孢粉分析方法对四川省红原县日干乔地区泥炭剖面进行了系统研究,建立了4个孢粉组合带。孢粉记录反应了红原县日干乔地区经历了潮湿-干燥-潮湿的气候变化过程。
A peat section at Riganqiao region was systematically studied using the 14C method and sporopollen analysis, three ecological zones could be recognized during these periods. The climate evolution in the Hongyuan area since the Late-glacial epoch reflected by sporopollen records experienced a wet-dry-wet climate change process.
