摘要:
为进一步确定影响朽木生地衣物种分布的环境因素，在托木尔峰自然保护区的北坡海拔1 950~2 750 m地带选择18个样地对朽木生地衣物种多样性及其物种分布格局进行了研究。结果表明，地衣种类的多样性和朽木径阶、海拔和腐蚀阶段之间有显著的相关性。地衣种类与朽木径阶的相关性系数R2为0.624 7，50~75 cm径阶的朽木上地衣的多样性最大。地衣群落的结构和物种组成随着海拔高度发生变化，其相关性系数R2为0.776 8，一般在海拔1 950~2 150 m的地带朽木上地衣群落的物种丰富度最高。不同腐蚀阶段的朽木上地衣种类和丰富度间存在显著性差异。
Abstract:
In order to further evaluate the relationship between environmental factors and distribution of lichens on dead wood, the paper focused on biodiversity and species distribution pattern of dead wood lichens from 18 sites along an altitudinal gradient from 1 950 m to 2 750 m on the north slope of Tomur Peak National Nature Reserve. The results showed that there was a clear relationship between lichen species richness with diameter class, altitudinal gradient and wood decay stage. The relationship between tree diameter class and number of lichen species gave a value of R2=0.624 7. The greatest number of lichen species was in the tree diameter class at 50-75 cm. Elevation affected both the number and diversity of the colonizing lichens. The relationship between the altitude and number of lichen species was designated as R2=0.776 8. The greatest lichen species richness on dead wood was found at 1 950-2 150 m. Finally, the lichen community composition varied with wood at different decay stages.
