Abstract

This paper seeks to understand the relationship between air temperature change and annual stem recruitment of the Betula ermanii population at the local scale in the upper treeline, based on data between 1953 and 2008 from field observations, tree-ring analysis, and meteorological station records, and using statistical analysis and mathematical simulation. Different propagation forms and annual stem recruitment of the Betula ermanii population responded significantly to the increase of air temperature. Under global warming, the population expansion and the domain enlargement of Betula ermanii led to a treeline shift. The population has continued to vary its physiological traits to adapt to air temperature change
