摘要
本文以样点为对象,以岩面生地衣的盖度为指标,采用聚类分析和除趋势对应分析对博格达峰南坡的岩面生地衣群落进行数值分类,应用典范对应分析法研究岩面生地衣种类分布与环境因子间的关系.结果表明:博格达峰南坡岩面生地衣共有68种,隶属于10目17科25属.依据多元数据分析结果,可将该地区岩面生地衣群落划分为4个群丛.群丛1:分布在样点1、4、10和12中,包括20种地衣种类,命名为丽石黄衣+碎茶渍群丛(Assoc. Xanthoria elegans(Link) Th. Fr.+Lecanora argopholis(Ach.) Ach.);群丛2:分布在样点5、6和11中,包括21种,命名为茸刺山褐梅+粉芽石黄衣群丛(Assoc. Montanelia tominii(Oxner) Divakar et al.+Xanthoria sorediata (Vain.)Poelt);群丛3:由样点2、3、7、8、9和13组成.常见的地衣种类有34种,命名为莲座黄茶渍+厚瓣茶衣群丛(Assoc.Candelariella rosulans(Müll.Arg.) Zahlbr.+Lobothallia crassimarginata X.R. Kou&Q. Ren);群丛4:包括样点14、15、16、18、19和20,由41种组成.命名为科罗拉多黄梅+韦伯黄梅群丛(Assoc. Xanthoparmelia coloradoensis(Gyeln.) Hale+Xanthoparmelia weberi(Hale) Hale).相似性分析结果表明:群丛3和群丛4的相似性最高,Whittaker和Jaccard’s相似性指数分别为0.455和0.193;群丛2和群丛4之间的相似性最低,分别为0.272和0.114.Shannon-Weiner物种多样性分析结果显示:群丛4的多样性最大为3.392;群丛3为3.283.典范对应分析结果表明:博格达峰南坡岩面生地衣群落的物种组成及其物种分布主要受到海拔、坡向以及不同地衣种类对环境的适应能力差异等因素的影响.
In this paper saxicolous lichen communities in southern slope of Bogda mountains were numerically classified based on species coverage by Cluster Analysis(CA)and Detrended Correspondence Analysis(DCA).The relationship between species distribution of saxicolous lichen and environmental factor was studied by Canonical Correspondence Analysis(CCA).The results show that,there are 68 species belonging to 25 genus in 17 families of 10 orders in saxicolous lichen were distribute southern slope of Bogda mountains.According to quantitative analysis results,the saxicolous lichen communities were classified following four associations.Association 1(Assoc.Xanthoria elegans(Link)Th.Fr.+Lecanora argopholis(Ach.)Ach.),Association 2(Assoc.Montanelia tominii(Oxner)Divakar et al.+Xanthoria sorediata(Vain.)Poelt),Association 3(Assoc.Candelariella rosu-lans(Mull.Arg.)Zahlbr.+Lobothallia crassimarginata X.R.Kou&Q.Ren),Association 4(Assoc.Xanthoparmelia coloradoensis(Gyeln.)Hale+Xanthoparmelia weberi(Hale)Hale).The similarity analysis result shows that species similarity between Association 3 and 4 was highest,the similarity indexes of whittaker and Jaccadas were 0.455 and 0.193 respectively,the lowest similarity the between Association 2 and 4 were 0.272 and 0.114 respectively.The Shannon-Weiner diversity analysis result shows that,Association 4 has highest species diversity(3.392),after than Association 3(3.283).The CCA analysis result shows that,the species composition and distribution pattern of the saxicolous lichen communities in southern slope of Bogda Mountains were related with the factors such as elevation,aspect and the adaptability of different types of lichens to the environment.
