| 1 | Annual temperatures during the last 2485 years in the mid-eastern Tibetan Plateau inferred from tree rings显示文摘By combining living trees and archaeological wood, the annual mean temperatures were reconstructed based on ring-width indices of the mid-eastern Tibetan Plateau for the past 2485 years. The climate variations revealed by the reconstruction indicate that there were four periods to have average tem- peratures similar to or even higher than that mean of 1970 to 2000 AD. A particularly notable rapid shift from cold to warm, we call it the 'Eastern Jin Event', occurred from 348 AD to 413 AD. Calculation re- sults show that the temperature variations over the mid-eastern Tibetan Plateau are not only repre- sentative for large parts of north-central China, but also closely correspond to those of the entire Northern Hemisphere over long time scales. During the last 2485 years, the downfall of most major dynasties in China coincides with intervals of low temperature. Compared with the temperature records in other regions of China during the last 1000 years, this reconstruction from the Tibetan Plateau shows a significant warming trend after the 1950s. | Hans W.

| 2 | 青藏高原中东部过去2485年以来温度变化的树轮记录显示文摘通过青藏高原东北部现生活树与墓葬古木相衔接,利用树轮宽度重建了这一地区过去2485a以来的年均温度变化序列.这个温度序列所揭示的气候历史表明序列中有4个时期的温度高于或接近1970~2000AD的平均温度.348~413AD出现过一次快速的由寒冷到温暖的气候突变事件,文中称之为'东晋事件'.计算表明,高原中东部长时间尺度温度变化不仅反映了中国中北地区,同时也响应了北半球的温度变化.在过去2485a里,中国绝大部分朝代的灭亡都与该温度序列的低温时期相对应.此外,与中国其他地区的温度记录相比较,高原中东部在1950年代之后升温幅度更高一些. | 刘禹 安芷生 Hans W.

| 3 | Amplitudes, rates, periodicities and causes of temperature variations in the past 2485 years and future trends over the central-eastern Tibetan Plateau显示文摘Amplitudes, rates, periodicities, causes and future trends of temperature variations based on tree rings for the past 2485 years on the central-eastern Tibetan Plateau were analyzed. The results showed that extreme climatic events on the Plateau, such as the Medieval Warm Period, Little Ice Age and 20th Century Warming appeared synchronously with those in other places worldwide. The largest amplitude and rate of temperature change occurred during the Eastern Jin Event (343-425 AD), and not in the late 20th century. There were significant cycles of 1324 a, 800 a, 199 a, 110 a and 2-3 a in the 2485-year temperature series. The 1324 a, 800 a, 199 a and 110 a cycles are associated with solar activity, which greatly affects the Earth surface temperature. The long-term trends (>1000 a) of temperature were controlled by the millennium-scale cycle, and amplitudes were dominated by multi-century cycles. Moreover, cold intervals corresponded to sunspot minimums. The prediction indicated that the temperature will decrease in the future until to 2068 AD and then increase again. | LIU YU CAI QiuFang SONG HuiMing AN ZhiSheng Hans W.

| 4 | 青藏高原中东部2485年来温度变化幅度、速率、周期、原因及未来趋势显示文摘分析了根据树木年轮资料重建的青藏高原中东部过去2485年来温度变化幅度、速率、周期、原因及未来趋势,发现研究区极端气候事件与全球同步出现,如中世纪暖期、小冰期和20世纪增温等.历史上最大的温度变幅和速率都发生在"东晋事件"(343-425AD)期间,而非20世纪后半期.过去青藏高原中东部地区温度序列存在显著的1324,800,199,110,2-3a的准周期(P〈0.01),其中,1324,199和110a周期与太阳活动有关.温度变化在很大程度上受控于太阳活动:千年尺度周期决定了温度变化趋势长期走向,百年尺度周期控制了温度变化幅度,而太阳活动极小期对应冷期出现.预估结果显示未来这一地区温度将下降,到2068AD前后温度下降到谷底,2068AD后再次升温. | 刘禹 蔡秋芳 宋慧明 安芷生 LINDERHOLM Hans W. | 2011 | 科学通报2011，56，25： | 11 |
| 5 | Tree-ring-based annual precipitation reconstruction in Kalaqin, Inner Mongolia for the last 238 years显示文摘A tree-ring-width chronology of Pinus tabulaeformis from Kalaqin, Inner Mongolia was developed using modern dendroc hronological techniques. Based on the results of correlation function analysis, the total precipitation from the previous August to current July was reconstructed for 1771-2008 AD with an explained variance of 49.3%. The reconstruction correlated well with the dryness/wetness series derived from historical documents, as well as the precipitation reconstruction of the Chifeng-Weichang region. There were eight intervals with greater precipitation than the average (associated with the strong East Asian summer monsoon) and seven intervals lower than the average (weak monsoon). A power spectrum analysis showed that there were 120 a, 80 a, 8 a and 2 a periodicities. | LIU Yu WANG CaiYong HAO WenJun SONG HuiMing CAI QiuFang TIAN Hua SUN Bo Hans W.

| 6 | 利用树轮宽度重建过去238年来内蒙古喀喇沁年降水量显示文摘根据树轮气候学实验步骤,经过精确交叉定年,建立了内蒙古喀喇沁地区油松树木年轮宽度年表.相关函数分析表明,树轮宽度年表与上年8月至当年7月的降水总量显著相关,在此基础上设计转换方程,重建了该地区1771~2008AD之间上年8月至当年7月的降水总量,方差解释量达49.3%(调整自由度后为47.1%).重建序列可与邻近赤峰-围场地区已有的树轮降水序列进行良好对比.在1771~2008AD期间有8个降水量较多的时期(高于多年平均值)和7个降水量较少的时期(低于多年平均值),分别反映了东亚夏季风较强和较弱的时期.功率谱分析检测出重建降水序列含有120,80,8和2a左右的准周期. | 刘禹 王财勇 郝文俊 宋慧明 蔡秋芳 田华 孙铂 LINDERHOLM Hans W. | 2011 | 科学通报2011，56，25： | 6 |
