摘要: 以芦芽山荷叶坪亚高山草甸为研究对象,共设置150个5 m×5 m草本样方,进行群落生物学调查,对研究区36种草本植物重要值、α多样性指数、谱系多样性指数及其相关性进行研究.结果表明: 荷叶坪亚高山草甸物种多样性总体分布较均匀,边缘地区物种更丰富,呈现“边缘效应”;4个样地的群落谱系结构呈聚集模式,12个样地的群落谱系结构呈分散模式;谱系多样性指数(PD)与Petrick指数、Simpson指数和Shannon指数呈正相关,净亲缘关系指数(NRI)和最近种间亲缘关系指数(NTI)与α物种多样性指数无明显相关性.

Abstract: In this study, investigation on plant community was conducted in Heyeping subalpine meadow of Luya Mountain in Shanxi Province of China. The importance values of 36 herbaceous species, α diversity index, phylogenetic diversity index, as well as their correlations were investigated. The results showed that the species diversity of the subalpine meadow was uniformly distributed. Species richness was higher in marginal areas, indicating an ‘edge effect’. The phylogenetic structure of four plots was convergent and that of 12 plots was dispersive. The phylogenetic diversity index (PD) was positively correlated with the Petrick index, Simpson index and Shannon index, while there was no significant correlation of either the net relatedness index (NRI) or the nearest taxon index (NTI) to the α diversity indices.
