摘要:

通过对梵净山东北部岩高坪区域苔藓植物以及对黔金丝猴活动区生境的研究，报道了黔金丝猴活动区苔藓植物46科，85属，249种（含种以下分类单位），其中贵州新记录种5个。从该区苔藓植物的组成看，温带区系成分最为丰富，占整个区系成分的43.32%；不同海拔的森林植被下苔藓植物的分布有明显的差异：阔叶林的苔藓植物多样性最高，竹林内苔藓植物多样性较低。在黔金丝猴活动最为频繁的海拔1 200～1 800 m范围内，苔藓植物的多样性也反映着该海拔阶段的生境是黔金丝猴最适宜的活动区。

Abstract:

Bryophytes diversity was studied at Yangaoping in the northeast of Fanjingshan National Nature Reserve. The results indicated that there were 46 families，85 genera，and 249 species(including the following categories units)of bryophytes，five species were new to Guizhou in this aera where Guizhou snub nosed monkeys occur very frequently. The component with flora of temperate zone was the most abundant and accounted for 43.32%，the bryophytes diversity in different altitude showed obvious differences，the broadleaved forest and evergreen mixed forest at higher altitude had more bryophytes than the bamboo forest at lower altitude. The altitude zone between 1 200 m and 1 800 m is used most frequently by Guizhou snub nosed monkey. The bryophytes biodiversity also reflected that the stage of the elevation habitat was the most appropriate activity area of Guizhou snub nosed monkey.
