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.
