摘要

利用树木年轮气候学方法,根据马尾松生长对气候变量具非线性响应,尝试重建江苏暖湿地区过去116年(1874~1990)的年平均气温和降水量。温度的重建效果优于降水量,实测值与重建值两者的缩减误差(RE)分别为0.12和0.10,两者的平均偏差百分率分别为2.3%和20%。绝大部分重建结果可从观测记录和历史文献中得到验证,但在温度较高或降水量较多的若干年份,实测值与重建值有较大偏差。

Abstract

The average annual temperature and annual precipitation were reconstructed for past 116 years ( 1874- 1990) under the nonlinear response function of Pi'inr~s mn.ssurrinna to climate by the methods of dendrochronology. The effect of reconstructed temperature was better than that of the precipitation. the reduction errors (RE) and percentage average of residuals for temperature and precipitation were 0. 12, 0. 10, 2. 3% and 20% respectively. The reconstruction could be verified by the observed data and other historical records for most years, while in the several years with higher temperature and precipitation, the residuals between estimated and observed values too large to be accepted.
