Abstract

The population of the dominant tree species of the Baima Snow Mountains in northwestern Yunnan, Abies georgei Orr, was investigated with a vegetation survey and tree-ring analysis. Structural and age characteristics were used to indicate the process and rates of geographical change, and the altitudinal range and size of forest were predicted using GIS with various climate change scenarios. The greatest increase of recruitment has occurred near the upper treeline on north-facing slopes, and the regeneration rate has been reduced at and below its once-optimal altitudinal range. The AA. demonstrate that the study of both upper and lower species limits of migrating subalpine species is crucial for predicting forest change, and suggest the involvement of spatial (geometry) as well as temporal (climate) factors in the shifting of alpine treeline
