中亚区域树木年轮气候学研究进展
Advance in Dendroclimatology in Central Asia
中文摘要：
中亚地处亚欧大陆中部，距海较远，是典型的中纬度干旱半干旱区域，在全球变化研究中占有特殊地位。其山区分布着大量对气候响应敏感的针叶树种原始森林，是树轮气候研究的理想区域。干旱的气候条件不仅使该地区树木对气候变化响应敏感，同时也有利于长龄树的生长和古木的保存，这为研究过去气候和环境变化提供了可靠的代用资料。对国内外在中亚区域开展树木年轮气候研究的现状和进展进行了综述，探讨了树轮记录的这一地区历史时期温度和湿度变化特征，总结了气候变化规律，并为进一步开展中亚树轮气候研究提出建议与展望。

Abstract：
Central Asia is located in the middle of the Eurasian Continent and far from ocean. It’s a typical arid and semi-arid region in the middle latitudes, and is in a special position for the study of global change. There are a large number of conifer primeval forests in the mountainous, which are sensitive to climate response. The arid climate conditions not only make the trees sensitive to climate change in this area, but also have benefts on the growth of old trees and the preservation of ancient trees. These provide reliable alternative data for the study of past climate and environmental changes. This paper summarizes the present situation and progress of the research on tree-ring climate in Central Asia, discusses the change characteristics of temperature and humidity, which are recorded by tree-ring in this region, summarizes the law of historical climate change, and puts forward some suggestions and prospects for further research on dendroclimatology in the Central Asia.
