Overview

[Objective] ect the provenances adaptive to future's climate change.[Method] The different responses of tree ring width of fifty-two provenances to climate were studied by the method of dendroclimatology.[Result] It indicated that the response of the whole tree ring width, earlywood width and latewood width to mean annual temperature was obvious, the maximum correlation coefficients are -0.515, -0.590 and -0.451 respectively. The response of the whole tree ring width, earlywood width and latewood width to the maximum annual temperature was also obvious. The maximum correlation coefficients are -0.482, -0.624 and -0.499 respectively.[Conclusion] In recent years, there is an increasing trend of mean annual temperature of test plot, which will be unfavorable to tree growth to a certain extent. It will be an effective way to solve this problem to select appropriate provenance in the process of afforestation. [目的] 为选择适合试验区域未来气候变化条件下生长的杉木种源，[方法] 运用年轮气候学方法，研究52个杉木地理种源3个树轮宽度指标对气候因子的响应。[结果] 整轮宽度、早材宽度和晚材宽度与年平均气温的响应呈强负相
