摘要：[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关关系,相关系数最大值分别为-0.515、-0.590和-0.451;整轮宽度、早材宽度和晚材宽度与年最高气温均呈强负相关关系,相关系数最大值分别为-482、-0.624和-0.499。[结论]未来试点年平均气温有升高的趋势,这将会在一定程度上抑制杉木的径向生长,而选择对温度响应不太敏感的湖南江华、广西博白和广西资源种源在试验林所在区域进行造林,将是解决这一问题的有效途径。
[ Objective ] To select 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 able to tree growth to a certain extent. It will be an effective nance in the process of afforestation. annual temperature of test plot, which will be unfavorway to solve this problem to select appropriate provenance in the process of afforestation.
