摘要: 采用相似性系数和物种多样性指数对北京百花山自然保护区8种植被内地面生苔藓植物的物种多样性进行了研究,得知8种植被中地面生苔藓植物有13科31属65种(含种以下的单位),优势科6科,优势种12种。不同植被中苔藓植物的物种组成、优势科和优势种不同,丛藓科和真藓科植物在草甸和灌丛内占绝对优势,而森林植被内的绢藓科为绝对优势科;油松林和落叶阔叶混交林的物种相似性最高为51.63,草甸和荆条灌丛与大部分植被的物种相似为0。地面生苔藓植物的分布与其生长的基质相关性最大,另外水分条件、小生境、草本层盖度和凋落物盖度等也影响地面生苔藓植物的分布。白桦林和落叶阔叶混交林应成为生物多样性保护的重点植被类型。

Abstract: By means of species similarity coefficient and species diversity index, the characteristics of species diversity of floor bryophytes in the Baihua Mountain National Nature Reserve in Beijing were studied. The results showed that there were 65 floor species (including subspecies and varieties) belonging to 31 genera of 13 families. Species composition, dominant families and dominant species were different in 8 kinds of vegetation, Pottiaceae and Bryaceae were the absolute families in meadow and shrub, but the Entodontaceae was the most common family in forest vegetation. The species similarity between Pinus tabulaeformis forest and deciduous broadleaved forest was the highest (0.516 3), but meadow and Vitex negundo shrub between mostly forest vegetation were zero. The growth base was the most important environment factor related to the distribution of floor bryophytes, and the humidity, herbage coverage, litter coverage were also related to the distribution of the bryophytes on floor. Betula platyphylla forest and deciduous broadleaved forest were the center of bryophyte diversity and the key area for the bryophyte diversity conversation.

Key words: floor bryophytes, species diversity, different vegetation, Baihua Mountain National Nature Reserve in Beijing
