树附生苔藓植物多样性及其影响因素

树附生苔藓植物是一类附生在树木上的苔藓植物,是森林生态系统的重要组成部分,在维持生物多样性和生态系统功能等方面发挥着重要的作用。由于树附生苔藓植物结构简单,对环境变化尤为敏感,常在大气污染、气候变化、森林干扰等方面作为指示生物。随着全球变化的加剧,其多样性势必会受到影响。因此,研究树附生苔藓植物多样性分布及其对不同环境因子的响应,对于全球变化背景下树附生苔藓植物的保护和利用具有重要的指导性意义。首先对树附生苔藓植物多样性和空间分布现状进行阐述,然后从附主树木特征、森林群落特征和全球变化等3个方面探讨树附生苔藓植物多样性与影响因素之间的关系,以期从"个体-群落-全球"不同尺度进行分析,为树附生苔藓植物的保护和利用等研究提供借鉴和参考。

Epiphytic bryophyte diversity and its influencing factors

Epiphytic bryophytes are a type of bryophytes that grow on the bark of trees. They are important components in the forest ecosystem and play vital roles in maintaining biodiversity and ecosystem functions. Epiphytic bryophytes are sensitive to the environmental changes for their simple structure and often used as bioindicators for air pollution, climate change, and forest disturbance. Meanwhile, epiphytic bryophytes diversity is under threat in the face of global change. Therefore, it is important to study the distribution and responses of epiphytic bryophytes to different environmental factors for their protection and utilization under the background of global change. In this paper, we reviewed studies on the biodiversity and spatial distribution of epiphytic bryophytes, and then discussed the relationship between their diversity and influencing factors from three aspects: host characteristics, forest community characteristics and global change. We hope that the comprehensive discussion from the individual-community-global scales can provide useful information for epiphytic bryophytes protection and utilization.
