由于分布广泛、分辨率高、定年准确和气候敏感性好等原因,树木年轮在重建过去区域、半球甚至全球气候环境变化中扮演着重要角色。天山地处中亚干旱区,气候变化波动大,对全球变化响应敏感,植物生长的干旱胁迫作用强烈,天山山区分布有大量雪岭云杉和西伯利亚落叶松等长龄且对气候敏感的针叶树种,因此天山山区是树轮气候研究的理想区域。天山山区树轮气候研究始于20世纪70年代,尤其是近10 a有了长足的进步,有关天山山区树轮气候研究已经在国际上有一定影响。本文通过综述国内外对天山山区树轮气候研究的现状和进展,总结了近200 a基于树轮资料的天山山区较为一致的气候变化规律,并为进一步开展天山山区树轮气候研究提出建议。天山山区未来树木年轮气候学研究应在开展大量不同区域树木年轮气候学重建基础上,尝试理解树木径向生长对气候的响应机理研究,同时选用不同数理方法和多树木年轮指标进行长时间尺度和大空间范围重建工作,并讨论中亚干旱区过去千年气候变化的影响机制。
Due to its wide distribution, high resolution, accurate dating and good climate sensitivity, tree rings play an important role in rebuilding the past regional, hemispheric and even global climate and environment. Tianshan Mountain is located in the arid zone of Central Asia where climate change fluctuates greatly and is sensitive to global changes. The drought stress of plant growth is strong. There are a large number of climate-sensitive conifer species such as Spruce and Siberian Lark, , So Tianshan Mountain is the ideal area for tree ring climate research. The research of tree-ring climate in Tianshan Mountains began to make great strides in the 1970s, especially in the past 10 years. The research on the tree-ring climate in Tianshan Mountains has had a certain impact in the world. In this paper, we summarize the current situation and progress of research on tree-ring climate in Tianshan Mountains at home and abroad, summarize the consistent climate change law of Tianshan Mountain based on tree-ring data in recent 200 years, and put forward suggestions for further research on tree-ring climate in Tianshan Mountains. Tien-Shan mountain future tree-ring climate research should be carried out in a large number of different regions of the tree-ring climatic reconstruction based on the attempt to understand the tree radial growth on the climate response mechanism, while using different mathematical methods and the tree ring index Time scale and large-scale spatial reconstruction, and discuss the mechanism of climate change in past arid regions of Central Asia.
