摘要
应用数量分类 (TWINSPAN)和排序 (DCA)方法 ,对新疆博格达山苔藓植被进行了多元分析。TWINSPAN结果表明 ,该地区苔藓植被可分为 6个主要群落类型 ,即牛角藓 真藓 (Cratoneuron_Bryum)群落、扭口藓 墙藓 (Barbula_Tortula)群落、提灯藓 细罗藓 (Mnium_Leskeella)群落、对叶藓 提灯藓 (Distichium_Mnium)群落、墙藓 连轴藓 (Tortula_Schistidium)群落、扭口藓 紫萼藓 (Barbula_Grimmia)群落 ,它们分别分布于山地荒漠带、山地草原_灌丛带、山地河岸林带、山地针叶林带、亚高山_高山草甸带、高山砾石带。DCA结果同TWINSPAN分析结果一致 ,并可知决定苔藓植物群落类型分布的环境因子主要是土壤含水量和降水量。
Quantitative classification(TWINSPAN) and ordination (DCA) methods were used to study the distribution patterns of 60 species of bryophytes occurring in 60 sites in Bogda Mountain, Xinjiang. TWINSPAN results showed that the bryophyte communities of Bogda Mountain could be divided into 6 groups, which are distributed in mountain desert, mountain grass_shrub belt, mountain river bank forest, mountain conifer forest, subalpine and alpine meadow and alpine stone belt respectively. These types can be named as follows: Cratoneuron_Bryum community, Barbula_Tortula community, Mnium_Leskeella community, Distichium_Mnium community, Tortula_Schistidium community, Barbula_Grimmia community and so on. DCA results were consistent with TWINSPAN results, and showed species distribution patterns correlated with major environmental variables of soil moisture and rainfall.
