摘要
为了解贵阳市地衣物种多样性及其分布特征,采用样方法和样线法进行实地调查。利用分子生物学、形态学等方法并参考相关文献资料,对该研究区的地衣进行分类鉴定和整理。研究结果表明:贵阳市地衣物种资源丰富,共发现地衣12科18属36种,包括贵州新记录科2个,新记录属2个,新记录种21个;优势科为梅衣科(Parmeliaceae)、蜈蚣衣科(Physciaceae)、石蕊科(Cladoniaceae),优势属为哑铃孢属(Heterodermia Trevis.)、石蕊属(Cladonia P.Browne)。研究区地衣根据生长形式类型分为枝状、叶状和壳状3种类型,其中叶状和枝状地衣种类最多,占总种数的52.78%、36.11;根据着生基物类型分为土生、石生和树生3种类型,其中树生地衣种类最多,占总种数的61.12%。该地区地衣区系被划分为世界广布成分、环北极成分、温带成分、泛热带成分和东亚成分5个类型;通过与贵州省内其他5个地区进行对比分析,结果显示贵阳市与黔西南州、遵义市、黔东南州属的相似性最高,与遵义市和铜仁市种的相似性最高。该研究为贵阳市及贵州省后续对于地衣的研究提供了重要的理论基础。
In order to understand the species diversity and distribution characteristics of lichens in Guiyang City,the sampling method and transect method were used to conduct field investigations.Using molecular biology,morphology and other methods and referring to relevant literature,the lichens in the study area were identified and sorted.The results prove that the lichen resources are rich in Guiyang City,and a total of 36 species in 18 genera,12 families are found,including 2 newly recorded families,2 newly recorded genera and 21 newly recorded species in Guizhou.The dominant families are Parmeliaceae,Physciaceae and Cladoniaceae,and the dominant genera are Heterodermia Trevis.and Cladonia P.Browne.Three growth forms of lichens are found:fruticose,foliose and crustose,among them foliose and fruticose lichens are the most diverse,account for 52.78%and 36.11%of the total species.According to the type of substrate,they belong to three types:autochthonism,lithophyte and arboreal,among which the arboreal lichens are the most,accounting for 61.12%of the total species.The lichen floristics include cosmopolitan element,circumpolar element,temperate zone species,pantropical element and east Asian element.Through comparative analysis with five other regions of Guizhou Province,it is showed that the similarity of lichen genus in this region with those in Qianxi Prefecture,Zunyi City and Qiandongnan Prefecture is the highest,and the similarity of lichen species in this region with thosein Zunyi City and Tongren City is the highest.This study provides an important theoretical foundation for the subsequent research on lichens in Guiyang City and Guizhou Province.
