摘要：研究四川卧龙亚高山森林岷江冷杉和铁杉树木年轮与气候因子的关系。结果表明:川西亚高山针叶林树木径向生长主要受气温的制约,卧龙地区岷江冷杉树轮宽度序列与当年2和4月月平均气温显著正相关(P≤0.05),而与多数月平均降水量和月平均相对湿度负相关;铁杉树轮宽度序列与上一年7月和当年2—4月月平均气温显著正相关(P≤0.05),与上一年10月和当年5月月平均降雨量显著正相关(P≤0.05),而与上一年7月及当年4和9月月平均相对湿度显著负相关(P≤0.05)。
By using the tree-ring samples of Abies faxoniana and Tsuga chinertsis collected from sub-alpine forests in Wolong Sichuan in 2010, the tree-ring width standard chronologies and residual chronology were established. A. faxoniana and T. chinensis tree-ring chronology in this region contains worthy climate information. The calculation results showed that A. faxoniana and T. chinensis tree-growth and tree-ring width chronologies were significantly positively correlated with the mean air temperature, suggesting that it was the restriction factor for the tree growth. In study area, the tree-ring width of A. faxoniana was positively correlated to the mean monthly temperature in current February and April （ P ≤ 0.05）. The correlations of the tree-ring width of A. faxoniarta with monthly precipitation and relative humidity were being negative with the lots of months. The tree-ring width of T. chinensis was positively correlated to the mean monthly temperature last July and current February to April （P≤ 0.05） and to the monthly precipitation in last October and current May （P ≤ 0.05） , and was significantly negatively correlated with monthly relative humidity in last July and current April and September （ P ≤0. 05 ）. A. faxoniana tree-ring width chronologies was not significantly correlated with season average climate factors; but T. chinensis tree-ring width was significantly positively correlated with Spring temperature, and was significantly negatively correlated with Spring relative humidity （P ≤ 0.05 ）.
