摘要
本文基于黄土高原南部地区历史文献记录 ,对唐代气候冷暖波动特征进行初步研究。研究表明 ,799AD前后存在一次百年尺度的气候转寒 ,在 84 5 AD、880 AD附近还存在两次数十年尺度的气候波动。在数十年时间尺度上 ,气候寒冷与较高的气候变率相伴出现。唐代相应地区旱涝资料中没有发现冷暖变化与干湿变化在十年尺度上有显著的线性相关性。最后我们就气候波动与社会发展之间某些耦合现象作一初步的讨论。
Based on historical document records in south Loess Plateau, we analyzed the fluctuation characteristics of climatic change in temperature of Tang dynasty. We recognized one climatic abruption of hundred-year scale 799AD or so as well as two climatic abruptions on the time scale of several decades about 845AD & 880AD. On the time scale of several decades, cold climate correlates positively with high variability. In the case of Guanzhong area, it seems that warm climate correlates poorly with dry climate on decadal scale. Finally, we discussed some social effects of climatic change.
