Based on the data from field survey in subalpine meadow on Mt. Xiaowutai, Hebei Province, α diversity and β diversity of the meadow were analyzed through Shannon-Weaver index and S?rensen index analysis in this paper. The results are as follows: 1) Both diversity indexes change obviously with elevation, and α diversity and β diversity change dramatically at the elevations of around 2300 m and 2700 m. 2) The order of α diversity index, from high to low, is Eastern > Western > Southern > Northern. β diversity reflected by S?rensen index increases when slope exposure changes. 3) Higher α diversity, but lower β diversity is observed on the mid-slope or the mid-bottom slope. The value of β diversity depends mostly on the range of elevation, normally between 2300 m and 2750 m, the β value reaches the highest.
