| Abstract: | In order to make clear the spatial distribution of timberline vegetation and its ecological adaptability,we quantified the characteristics of the vegetation in the timberline ecotone on Mt.Shergyla in Tibet using multivariate analysis (TWINSPAN classification and DCA ordination) of the importance values of the plant species (herb,shrub and tree layer) in each of the 26 study plots.Results from TWINSPAN showed that along the timberline ecotone in an altitudinal range of 1 000 m,seven vegetation types (associ... |
