| 摘 要： | 根据近年来对过去2000a气候变化研究成果,通过遥感方法将罗布泊盐湖近2000a气候变化记录与不同地区、不同类型的气候变化曲线进行对比分析,探索了现代盐湖对气候事件的响应机制,并证明了罗布泊盐湖沉积物的气候变化曲线具有明确的古气候意义.研究表明在公元1300～1500a区间,罗布泊盐湖气候记录与北半球千年来地面空气温度变化的相关性大于0.8;千年尺度变化与古利雅冰芯曲线较一致,气候变化趋势是缓慢上升;600a以来,与北京石花洞石笋微层记录曲线有较好的相关性;相对于北半球区域气候,在公元13世纪前后出现过滞后现象. |

| Abstract: | According to the research result on the climate change during the past 2000a, the authors have compared the climate change record during the past 2000a in Luobupo with the climate change records in different regions and of different types by means of remote sensing, exploring the responding mechanism of climatic event in modern saline, and having proved that the climatic changing curve in the deposits in Luobupo is of definite paleoclimate meaning. The research result shows that the relativity between the air temperature variation data in the Northern Hemisphere during the past 1000a and that in Luobupo during the past 1300~1500a is 0.82, and that the climatic change in millennium scale is consistent with the curve of Guliya Ice Core with the rising tendency in temperature. It also shows that there is better relativity with the record in the stalagmite from Shihuadong in Beijing since in the past 600 years, but in contrast to the local climate in the Northern Hemisphere around the 13th century the climatic change in Luobupo was lagged behind during that time. |
