为了检测气候变化对厄尔曼桦树（Betula ermanii Charm.）的影响，本文研究了长白山地区分布上限的额尔曼白桦林径向生长与气候的关系。在海拔约1950米的6个林分中，对30棵埃尔曼桦树进行了取样。相关性和响应函数系数表明，前8月、10月和当前2月的气温，前冬季和当前3月、6月和9月的降水量对额尔曼桦径向生长有显著的正影响。此外，径向生长与前8月和当前6月日照比呈负相关。降水量和温度在年度化期间也积极影响的径向生长的埃尔曼的桦树。回归分析表明，降水解释更多的径向生长比最低温度的变化。总之，这些结果表明，气候通过改变土壤水分的有效性影响径向生长的埃尔曼的桦树。因此，即使在全球气候变暖的情况下，也不能仅用温度来预测长白山林线上的埃尔曼桦树的径向生长。
In order to detect the effects of climate change on Erman's birch (Betula ermanii Charm.), we examined radial growth—climate relationships of Erman's birch forests at their upper limit of distribution in Changbai Mountain, Northeast China. Thirty Erman's birch trees from six stands were sampled at an elevation of about 1950m a.s.l. Correlation and response function coefficients indicated that radial growth of Erman's birch was positively influenced by previous August, October and current February temperature, and previous winter, and current March, June and September precipitation. In addition, radial growth showed a negative relationship to previous August and current June sunshine ratio. Precipitation and temperatures in annualization periods also positively affected the radial growth of Erman's birch. Regression analyses indicated that precipitation explained more variation in radial growth than minimum temperature. Together, these results suggested that climate affected radial growth of Erman's birch through altering soil water availability. Therefore, the radial growth of Erman's birch at the tree line in Changbai Mountain could not be predicted by temperature alone even under a scenario of global warming.
