山西霍山油松林的物种多度分布格局

Aims Determination of species abundance distribution is important in research on species diversity.Our major objective was to determine species abundance distribution models to advance understanding of distribution mechanisms and to assist preservation of biological diversity.Methods Based on data collected from field surveys,we examined the species abundance patterns of tree,shrub and herb layers in Pinus tabulaeformis forest in Huoshan Mountain,Shanxi Province.We used niche preemption(NPM),broken stick(BS...
