摘要: 梵净山山顶苔藓矮林具有下述特点:1.根据其分布高度,区系组成,常绿树种和落叶树种的比例、重要值,生活型谱,可认为它是常绿落叶阔叶混交林的变型,是一种地形顶极群落。2.其特点是:林木矮小,分枝低,主干不明显,枝干多弯曲,树冠平伏紧密,生长缓慢,林内苔藓植物发达,种类组成贫乏,层次简单,藤本植物稀少。3.用极点排序法可把它们分成六个类型,即杜鹃槭树矮林、山樱山矾矮林、械树矮林、黔稠矮林、花楸杜鹃矮林和黄杨矮林。4.其更新特点是萌蘖占有重要地位,种子更新能力较弱,两者互相补充保证了矮林能自我更新,成为稳定的群落。5.梵净山山顶苔藓矮林经营的方向是认真保护。

Abstract: This paper is report on the investigation of thirty sample plots in Fanjinshan’s bryophytes and elfin torest The results are as follows: 1. According to the distribution altitude, floristic composition the ratio of quantity to importance vuale between evergreen and deciduous trees and the life form spectrum, Fanjinshan’s elfin forest is regarded as a form of mixed forest of evergreen and deciduous trees. It is an orographic climax community. 2. Its special features are shown as: dwarfism with lower branches and no obvious trunk, bended shoots, close and level crown, slow growth, more mosses in its woods, floristic poverty, simple structure of layers and liana is rare. 3. The method of polar ordination is used to classify the coppice into six types: Rhododendron, Acer community, Prunus, Symplocos community, Acer community, Cyclobalanopsis stewardiana community, Sorbus, Rhododendron community and Buxus sinica community. 4.As the coppice has the character that germinative regeneration occupies an important place and the seed regeneration ability is weak, but the two modes of regeneration mutually complement to guarantee its regeneration, so it still is a stable community. 5. The basis of management is earnest protection for the Fanjinshan′s coppice.
