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 C~(14)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 The past ten years of natural environment change in Tibet have been studied by some of the predecessors from the aspects of landform, Quaternary geology and paleobotany. In this paper, the peat of the plateau was taken as the research object, the spore-pollen analysis of 113 samples was carried out on six peat profiles and the C ~ (14) year order of 12 samples was measured. Then the paleoptile and palaeoclimate changes in the past ten thousand years in southern Tibet Law, the formation of peat swamp era and the accumulation of speed and other issues for a preliminary discussion
