凉水自然保护区苔藓植物资源调查

摘要

[Objective]To investigate the source situations of bryophyte in Liangshui nature reserve and provide reference basis for the development and utilization of bryophyte in Liangshui nature reserve.[Method]Using field survey and identification of specimen,the resources of bryophyte in Liangshui nature reserve were studied.[Result]There were 112 species of bryophyte in this nature reserve,belonging to 70 genera in 39 families.Among them,there were 17 species,13 genera,11 families of mosses,and 95 species,57 genera,28 families of liveworts.The north temperate floristic geographical elements were predominant in Liangshui nature reserve.Bryophyte community was divided into four types:hydrophytia,petrophytia,geophytia and epixylophytia in this area.[Conclusion]The richness of bryophyte in Liangshui nature reserve is not high,which might be related with climate and human interference.%[目的]调查凉水自然保护区苔藓植物资源状况,为该保护区苔藓植物的开发利用提供参考依据.[方法]采用野外调查和标本鉴定的方法,对凉水自然保护区苔藓植物资源进行了研究.[结果]该自然保护区共有苔藓植物112种,隶属39科70属,其中苔类11科13属17种、藓类28科57属95种.该地区区系地理成分主要以北温带成分为主.凉水自然保护区苔鲜植物群落可分为4种类型:水生群落、石生群落、土生群落和木生群落.[结论]凉水自然保护区苔藓植物的丰富度并不高,这可能与气候和人为干扰有关.
