| 摘 要： | 利用采自长白山红松和落叶松分布上限和下限的树轮样本,分别建立树轮宽度差值年表.结果表明:下限红松年表的平均敏感度、树轮宽度指数的年际变率、信噪比等年表特征值比上限年表的高,表明下限红松生长对环境的敏感性大于上限;落叶松年表特征值在不同海拔表现与红松相反.进一步分析发现分布上限和下限的红松生长与气候因子之间的关系不同.下...

| Abstract: | Tree-ring samples of Pinus koraiensis and Larix olgensis were studied along an altitudinal gradient on the northern slope of Changbai Mountains,Northeast China,and ring-width residual chronologies were developed for four sites at low and high elevations.Annual ring-width variability was different between elevation sites.For Pinus koraiensis,low elevation chronology had higher mean sensitivity(MS),standard deviation(SD) and signal-to-noise ratio(SNR),while high elevation chronology of Larix olgensis had high... |
