藏东南色季拉山苔藓植物研究

A Survey of Bryophytes in Sygera Mountains in Southeast of Tibet

为推动苔藓植物研究的成熟和完善,综合运用文献资料法,对藏东南色季拉山苔藓植物的组成概况、区系地理成分、影响因子、生态群落及生活型等方面进行了分析。结果显示:藏东南色季拉山苔藓植物共有56科、134属、356种。其中,苔类植物32科、52属、140种,藓类植物24科、82属、216种;藓类植物地理区系成分有15种类型,苔类植物地理区系成分有11种类型,苔藓植物地理区系成分有着显著的温带性质,兼具东亚性质,揭示了色季拉山自然环境的独特;影响因子是土壤因子、海拔、空气湿度、水分、光照、人类及牲畜活动等;生态群落以土生和石生群落占绝对优势,生活型是以丛集型和交织型为主要地位。通过此次的综合分析,有助于全面了解藏东南色季拉山的研究现状及进展,为今后的苔藓植物研究提供了基础资料。

In order to promote the maturity and perfection of bryophyte research,this study comprehensively analyzed and summarized the bryophyte composition,the floristic geographic elements,influencing factors,ecological community and life forms in Sygera Mountains in southeast of Tibet by using the method of literature.The results showed that there were 356 species of bryophytes belonging to 134 genera and 56 families in Sygera Mountains.Among them,there were 32 families,52 genera and 140 species of liverworts,and 24 families,82 genera and 216 species of mosses.The floristic geographic of bryophyte in Sygera Mountain is complex.There are 15 types of mosses and 11 types of liverworts.The bryophyte flora is of temperate and East Asian nature,which reveals the unique natural environment of Sygera Mountains;The influencing factors are soil factors,altitude,air humidity,water,light,human and livestock activities,etc.The ecological communities were dominated by soil-community and rock-community,and the life forms were mainly turfs and wefts.Finally,this comprehensive analysis is helpful to understand the research status and progress of Sygera Mountains in southeast of Tibet and provide basic information for future bryophytes.
