：
本研究选取祁连山自东向西6个样点祁连圆柏和1个样点的油松，讨论了研究区自有气象观测资料以来树木径向生长对主要气候因子的响应。分析结果表明，在近三十年祁连圆柏样点内单株树木与气候要素的响应关系具有显著变化；利用滑动相关分析方法研究得知，随着时间变化，单株树木与温度的相关一致性明显减弱，在近三十年有样点出现了明显的响应分异现象，相关关系呈现出明显的正负转化趋势。

冬春季的极端冷灾是我国南方一种严重的自然灾害。在气候变暖的背景下,近几年极端冷灾的频发受到了广泛关注。然而,目前关于我国南方极端冷灾的研究主要局限在器测资料时段,不足于理解极端冷灾的长期演变特征和驱动机制。本研究基于我国南方受寒潮影响较为频繁的湖南和江西地区5个样点(25-29°N,111-115°E)的树轮宽度资料重建了研究区过去160年(1849-2008年)的1-4月份气温变化历史。
高山林线是森林分布的海拔上限，对气候变化具有潜在的敏感性，在全球变化研究中日益受到关注.藏东南一带具有完整的植被垂直带，并分布着北半球最高海拔的林线.其中，藏东南色季拉山急尖长苞冷杉(Abies georgei var.smithii)垂直带和高山林线具有很好的代表性.本研究通过建立色季拉山不同海拔梯度上(3600-4400m)由21个急尖长苞冷杉样点组成的树轮网络，揭示了急尖长苞冷杉生长对气候的
