In this paper, we reviewed the analytical methods of dendrometer data, and concluded the progress of using dendrometer to monitor stem radial growth and tree water use in cold environments. We pointed out that a general explanation for the reduced sensitivity of cold-limited tree growth to summer temperature is still wanted, which may be closely related with the special seasonal pattern of stem radial growth in cold environments. Meanwhile, though dendrometer could monitor tree water use in cold environments, the response of tree water use to climate change remains unclear. Based on current researches, more focuses should be put on following fields: the potential effects of seasonal pattern of stem radial growth on the relationships between tree growth and climatic factors in cold environments, its comparison with other monitoring methods, its correlation with ecosystem-level measurements.
