根据树木年轮宽度反演历史气候资料,是气候变化研究及气候资源利用工作的重要基础.基于安格林和新青林场树木年轮宽度,利用其与临近站点气温、降水和日照时数之间的相关性,建立显著性水平高于0.25、平均相对误差小于30%的气候重建模型.结果表明：在选定研究因子范围内,大兴安岭北部典型地区树木年轮宽度受气温影响最大,受日照影响最小;重建方程中,气温类因子重建方程显著性水平较高,日照类因子重建方程显著性水平均较低;日照类因子模拟结果平均相对误差普遍低于10%,气温和降水类因子大部分模拟结果平均相对误差低于30%;在设定条件范围内,针对大兴安岭北部典型地区气温、降水和日照分别建立11、9和11个重建方程,可重建1707（1706）—1959年或1866（1865）—1959年资料,大兴安岭北部典型地区的可用气候资料延长至300（或150）a左右.

英文摘要：

Inversion of historical climate data based on widths of tree-rings is an important foundation for the study on cli-mate change and utilization of climatic resources. A climate reconstruction model was set up based on width of tree-rings of the trees in the Angelin forest farm and the Xinqing forest farm in the northern Daxing′anling Range and their correlations with the temperatures, precipitations and hours of sunshine around the neighboring weather stations, with significance lev-elbeing over 0.25 and average relative error being below 30%. Results show that among the factors studied in this project, temperature is the major one affecting width of tree-rings the most and hours of sunshine, the least in the region. Among the equations for climatic reconstruction, the equation based on temperature is the highest in significance level, while the equation based on hours of sunshine, the lowest. The simulation using factors, like hours of sunshine is generally lower than 10% in average relative error, while the one using factors, like temperature and precipitation, is lower than 30%. Within the designated scope of conditions, 11, 9 and 11 models are established, respectively, for reconstruction of tem-perature, precipitation and sunshine data of the region, respectively, and can be used to inverse the climate data of the years from 1707 （ 1706） to 1959 or from 1866 （ 1865） to 1959. Consequently, the climate data available for study of the region is greatly expanded to cover about 300 （ or 150） years.
