历史时期气候变化研究的一个重要方面,是获取高分辨率的古气候数据资料,弄清气候变化的事实,并建立历史气候的长序列.在我国,竺可桢利用物候资料和历史资料恢复了过去5000a来我国东部地区的温度变化曲线.吴祥定等在拉萨利用不同时期树木年轮资料衔接的方法,恢复过该地区2000a来的气候变化历史.姚檀栋等根据古里亚冰芯资料,给出了青藏高原近2000a来气候和环境变化的证据.本文将根据青海都兰地区树木年轮资料来讨论这一地区1835a间的气候变化趋势.本研究是我国目前在树木年轮气候研究方面资料较为完整和时间序列最长的一个.
An important aspect of climate change research in historical period is obtaining high-resolution paleoclimate data, clarifying the fact of climate change and establishing a long sequence of historical climate.In China, Zhu Kezhen recovered the past 5000a by using phenological data and historical data Came to the eastern part of China’s temperature curve.Wu Xiangding and other use of Lhasa in different periods of tree ring data convergence method to restore the region in 2000a to come from the climate change history.Yao Tan Dong et al on the basis of Gulia ice core data are given Qinghai-Tibet Plateau near 2000a climate and environmental changes in this paper will be based on the Qinghai Dulan annual tree ring information to discuss the trend of climate change in this region in 1835a.This study is China’s current tree ring weather information research is more complete and time series The longest one.
