文摘This paper examed the output of four niche models: niche preemption model, broken stick model, overlapping niche model, logarithmic series distribution, in application to three kind of communities of artificial vegetation in Antaibao open mine. The results showed that overlapping niche model could well fit to the species abundance distribution of forest community, while broken stick model could well fit to the thicket and meadow communities. Forest community was more adaptable for the special inhabitation than the thicket community and the meadow community. The regression between the parameters of logarithmic series distribution α and the classical community diversity index-Shannon-Winner index was liner. While there were the same ecological significance between the species-abundance diagram of models and the niche overlapping values of community.
