根据对新疆巴尔鲁克山国家级自然保护区朽木生地衣群落18个样点(20 m×20 m)调查的数据,以各地衣种的盖度为指标结合双向指示种分析方法(TWINSPAN)和除趋势对应分析法(DCA),对保护区朽木生地衣群落进行数量分类并分析了群落结构特征及其多样性和相似性。采用典范对应分析法(CCA)对各群落的物种分布格局与环境因子的关系进行了探讨。结果表明:TWINSPAN分析和DCA排序将分布在巴尔鲁克山自然保护区的20种朽木生地衣分为以下4个群落。群落1——矮石蕊(Cladonia humilis(With.)***)+犬地卷(Peltigera aphthosa(L.)Willd.)群落;群落2——喇叭粉石蕊(Cladonia chlorophaea(Floex Sommerf.)Spreng.)+土星猫耳衣(Leptogium saturninum(Dicks.)Nyl.)+枪石蕊(Cladonia coniocreae(Flk.)Spreng.)群落;群落3——平盘软地卷(Peltigera elisabethae Gyeln.)+犬地卷+多指地卷(Peltigera polydactyla(Neck.)Hoffm.)群落;群落4——膜地卷(Peltigera membranacea(Ach.)Nyl.)+喇叭粉石蕊+分指地卷(Peltigera didactyla(With.)***.)群落。物种多样性以群落2最大为3.478;群落1最小为2.716;群落2和群落4间的相似性最高为0.856,群落1和群落3相似性系数最低为0.434。朽木生地衣的分布与朽木树种具有专一性,分布在雪岭云杉上的地衣种类最多。CCA排序结果反映,该地区朽木生地衣的分布与森林植被郁闭度、光照强度、朽木腐蚀度的影响较大,而与朽木直径大小、朽木pH等因素的影响不大。
