利用树木年轮宽度资料重建长白山地区过去240年秋季气温的变化
Variation of autumn temperature over the past 240 years in Changbai Mountains of Northeast China: A reconstruction with tree-ring records
摘要
Abstract
This paper analyzed the relationships of Fraxinus mandshurica tree-ring width chronology with climatic variables in Changbai Mountains, and reconstructed the chronology of autumn mean temperature in this area in 1765-2005. There was a significant positive correlation between the tree-ring width and the autumn mean temperature of current year (P<0. 01). The reconstructed function was Taw%=6.001+6. 316XRES(#2=0. 386, /?*dj =0.358, P<0.001). Over past 240 years, the autumn temperature in Changbai Mountains fluctuated evidently, and the amplitude of the fluctuation was relatively stable. There were 8 colder periods and 6 warmer periods. During colder periods, the anomalies in 1816, 1817, and 1818 were greater than 1 °C , but in other years were less than 1 °C. Warmer periods were not obvious, and the time lengths were short. There were four warmer periods in 1794, 1795 , 1796, and 1797 , and the anomalies were greater than 1 °C. Wavelet spectral analysis indicated the existence of two significant cycles (8-16 and 3-5 years) of autumn mean temperature in the study area over past 240 years.关键词
