中文摘要: 树轮冰川学是一门研究过去冰川变化的学科,可为评价当前和预测未来冰川变化提供高精度、长时间的冰川变化数据,是树轮年代学的一个分支学科。本文从树轮冰川学的基本原理、藏东南地区树轮冰川学方法的发展、小冰期以来冰川进退的树轮测年结果,以及冰川进退与温度和降水量变化之间的关系这几个方面综述了青藏高原东南部地区树轮冰川学的研究现状。目前,树轮冰川学研究揭示出藏东南地区小冰期的6次冰川进退波动事件。温度对冰川进退起主要作用,降水作用较弱,主要为其提供物质积累。以后的研究中,需要进一步提高树轮测年证据的精确度、增加冰川前进和更老冰碛物的测年证据,以及测年证据的空间覆盖度,为揭示该地区小冰期以来冰川进退的时空特征及其对温度、降水量的响应关系提供翔实、可靠的数据。
英文摘要: Southeast Tibetan Plateau is the core distribution area of temperate glaciers in China. Dendroglaciology is a branch of dendrochronology that uses tree-rings to study the past glacier fluctuations. It could provide us long term and high-resolution data on glaciers to evaluate current glacier retreating and to predict possible future changes. Herein we provide a general review on the dendroglaciology study in southeast Tibetan Plateau,including the fundamental principles of dendroglaciology, development of dendroglaciological methods, dating results of glacier movements since the Little Ice Age (LIA) and the relationship of glacier changes with temperature and precipitation variations. To date, six events of glacier fluctuations were revealed since LIA in southeast Tibetan Plateau. Most evidences indicate that glacier fluctuations here are mainly affected by temperature variations on multi-decadal to centennial time scale. Precipitation has little effects on glacier, except the accumulation of mass. Generally, the current dating evidences are not enough to estimate the spatial-temporal characteristics of glaciers during the Little Ice Age in southeast Tibetan Plateau. The study on response time to climate is still limited by the accuracy of treering dating. Accordingly, more accurate tree-ring dating results with unified methods on elder moraines of more glaciers are needed to potray a clearer picture of the glacier fluctuations during the Little Ice Age in southeast Tibetan Plateau.
