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，并再也未能恢复起来
The radiocarbon dating and sporopollen analysis of the petrological profile of the Olive Dam in Xishuangbanna indicates that the swamp peat accumulation started at about 7250 aB. P. At that time, the vegetation in the olive dam basin was a tropical rainforest vegetation represented by Thousand Fruit and Radix Linnaeus, about 5690aB. P. Under the influence of climate change and human activities, the rainforests gradually disappear from the basin and can no longer be restored
