| 摘要: |
| 对采自山东塔山的黑松(Pinus thunbergii Parl) 树芯样本进行交叉定年后建立树轮稳定碳同位素序列（δ13C 序列）。将得到的树轮δ13C 序列进行校正以去除大气CO2的影响，提取其高频部分分析与气候要素的响应关系，发现黑松树轮δ13C 的高频序列与对应年份平均气温的响应比对降水量的响应显著。气温和降水对树轮δ13C 的影响均有滞后效应，即塔山地区树轮δ13C 能记录冬季气候变化。在相关分析基础上用回归方程重建了山东塔山地区近七十年冬春季节（即上年12 月— 当年5 月）的平均气温，分析发现重建序列有明显的冷暖交替上升的变化趋势。 |

| Abstract: |
| Tree-ring samples of Pinus thunbergii Parl at eastern Tashan in Shandong Province were collected to integrate the tree-ring stable carbon isotope series. In order to remove the influence of atmospheric CO2, extract the high frequency part of the tree ring δ13C. Analysis the response of tree ring δ13C series and climate factors, found that the response between tree ring δ13C and temperature is obvious than precipitation. There exists a lagging effect of the influence of both temperature and precipitation on tree-ring δ13C in some extent. This results indicated that tree ring δ13C in Tashan can record the winter climate change. On the basis of correlation analysis, utilize the regression equation to reconstruct near seventy years' average temperature in winter and spring season (i.e., from December last year to May current year). Analysis found that the rebuilding temperature series shows an obviously rise trend which cold and warm temperature change alternately. |
