摘要: 西藏地区近一万年来自然环境的变化前人曾从地貌、第四纪地质和古植物学等方面进行了一些研究。本文以高原泥炭为研究对象,对六个泥炭剖面进行了113块样品的孢粉分析,12块样品的 C14年令测定,进而对西藏南部一万年来古植被和古气候的变化规律、泥炭沼泽的形成时代及积累速度等问题进行初步探讨

Abstract: This paper takes the peat in plateau area as the object for this study.We have carried out pollen analysis of 113 samples taken from 6 peat sections at different sites and also the radiocarbon c14 dating of 12 samples.Based on these results,we have studied the pattern of variation of vegetation and climate,the genesis of peat swamp and its accumulation rate etc.of that region,in a period of the latest ten thousand years.
