Niche of Dominant Species of Larix principis-rupprechtii Communities in Wutai Mountain,Shanxi
Shannon-Wiener's index and Petraitis-s methods were used to analyze the niche breadth and overlap among 24 dominant species in the Larix principis-rupprechtii communities in Wutai Mountain,Shanxi. The results indicated that the species with sufficiently overwhelmingly broader niche breadth included Larix principis-rupprechtii , Carex lanceolata , Anthriscus sylvetris and Maianthemum bifolium , incontrast to those with the narrower niche breadth including PopuLus davidiana ,Saussurea jaPonica ,Allium victorialis and Rose davurica. The niche overlap was found only in 206 (37. 3％) among 576 dominant species piars. The less common niche overlap suggested the less severe competition in the communities. No absolutely general overlap among 24 dominant species was observed.
