对大围山国家级自然保护区山地雨林物种-多度格局研究表明:大围山原生及受人为干扰较小的山地雨林群落其乔木层树种的物种多度分布符合对数级数分布,物种间个体数的差异显著,表征了山地雨林群落的稀疏种数目远大于富集种.研究还表明:物种多度格局与物种多样性指数结合使用可更好地研究群落的结构特征,受人为干扰较小及相对发育成熟的山地雨林群落,具有较高的生物多样性和较大的稳定性.
The study on the species-abundance pattern of mountain rainforest in Dawei Mountain National Nature Reserve shows that the species abundance distribution of arborous tree species in native Mongolian rainforest communities and the less disturbed man-made forest in Dawei Mountain is in logarithmic order, The number of sparse individuals in the rainforest was much larger than that in the rich species.The study also showed that the combination of species abundance pattern and species diversity index could better study the structural characteristics of the community, The smaller and relatively mature mountain rainforest communities have higher biodiversity and greater stability.
