| 摘 要： | 利用长江三角洲史料优势, 重建公元820年代以来, 年代级冬温序列. 为测试古里雅冰芯记录的影响力, 与之作比较研究. 结果显示: 其年代级变化背景有很好的对应关系 , 年代级变化有大同小异的复杂情况. 舍弃量级, 就年代级温度, 降水升降, 约有一半是同步的, 且有大致对应的温湿组合. 说明两地虽远隔数千公里, 环境生态条件悬殊, 年代级气候变化仍有响应. 最后就形成响应的成因机制作初步分析.

| Abstract: | With the help of abundant historical documents in the Yangtze Delta, winter temperature starting from 820's AC has been reconstructed. In order to calibrate the effect of the record in Guliya ice core, a comparison of the winter temperature with the record has been established. The result shows that it was a close temporal and spatial relation before the 13 th century considering cold and warm variations. After the 13 th century, it is difficult to find a correlation. During the last 1000 a, a cold trend is clear in the Yangtze Delta, but a warm trend could be found in the record in Guliya ice core. This trend is resulted from the warm phase during the middle centuries (7 th and 8 th century) both in the Yangtze Delta and the whole China; however, the warm phase could not be seen in the record in Guliya ice core or in the Tibetan Plateau. During the Little Ice Age, 3 typical periods can be found both in Guliya and in the Yangtze Delta. The first phase of the Little Ice Age started earlier and concluded later in the Yangtze Delta than that in Guliya. As the decadal variation, nearly half of the peaks show a simultaneous change in both sites, but the changing amplitude is different. The composition of warm-cold also shows a similarity. Although there is a distance of several thousand kilometers for the two sites, the same decadal climatic response can still be found in the records of temperature and precipitation. Sun activities and volcanic eruptions dominate the regional climate change in both sites. |
