摘　　要：西双版纳橄榄坝泥炭剖面的放射性碳测年和孢粉分析研究表明，该沼泽泥炭堆积始于约７２５０ａＢ．Ｐ．，当时橄榄坝盆地的植被是以千果榄仁和龙脑香科为代表的热带雨林植被，约５６９０ａＢ．Ｐ．在气候变凉干和人类活动的双重影响下，热带雨林逐渐从盆地内消失。Pollen analysis and radiocarbon dating on a peat section at Ganlan basin,Xishuangbanna,reveals that the marsh was formed about 7 250aBP There was a tropic rain forest represented by Terminalia myriocarpa and Dipterocarpaceae Under the influences of the climate changing to cool and dry and human activities,the tropic rain forest disappeared gradually from the basin and didn′t recovered again since the year about 5 690aBP
