摘要
在神农架川金丝猴栖息地内选择17个样地,以树生地衣盖度为指标,应用TWINSPAN方法对样地内树生地衣群落进行数量分类,确定地衣群丛的类型;计算和分析了样地内各地衣群落的丰富度指数、物种多样性指数和均匀度指数。结果表明:(1)鉴定出树生地衣52种,隶属12科21属,这些树生地衣群丛可以分为8种类型:群丛I:波曲哑铃孢+硫黄袋衣群丛,群丛II:中国树花+栎缘毛衣群丛,群丛III:硫黄袋衣+针芽肺衣群丛,群丛IV:掌状绵腹衣+针芽肺衣+皱梅衣群丛,群丛V:杯树花日本变种+皱梅衣群丛,群丛VI:皱梅衣+亚洲藓发群丛,群丛VII:橄榄斑叶+拟橄榄斑叶群丛,群丛VIII:黄袋衣+粉缘斑叶群丛。(2)群丛间相似性指数最高的为群丛Ⅰ与群丛Ⅲ(0.321),其次为群丛Ⅲ与群丛Ⅳ(0.305),最低的为群丛Ⅱ与群丛Ⅷ、群丛Ⅳ与群丛Ⅷ,均为0.000;物种多样性指数最高的为群丛Ⅲ(2.062),其次为群丛Ⅴ(2.047),最低的为群丛Ⅱ(0.721);均匀度指数最高的为群丛Ⅰ(0.809),其次为群丛Ⅴ(0.802),最低的为群丛Ⅱ(0.301)。(3)神农架川金丝猴栖息地树生地衣群落物种多样性主要受湿度、温度、光照和海拔等环境因子的影响。
Corticolous lichen communities were numerically classified based on species coverage by twoway indicator species analysis （TWINSPAN） in habitat of Rhinopithecus roxellana of Shennongjia Nature Reserve, Hubei Province, China. Seventeen plots were established, types of lichen communities in these plots were defined, and species richness index, species diversity index and evenness index of each lichen communities were analyzed. The results indicated that： （1） There were 52 lichen species belonging to 21 genera in 12 families in the 17 plots, and these lichen species could be grouped into eight types： Association Ⅰ： Heterodermia tremulans ＋ Hypogymnia hypotrypa; Association Ⅱ： Ramalina sinensis ＋ Parmelina quercina; Association Ⅲ： H. hypotrypa ＋ Lobaria isidiophora; Association Ⅳ： Anzia opuntiella ＋ L. isidiophora ＋ Flavoparmelia caperata; Association Ⅴ： R. calicaris var. japonica ＋ F. caperata; Association Ⅵ： F. caperata ＋ Bryoria asiatica; Association Ⅶ： Cetrelia olivetorum ＋ Cetrelia pseudolivetorum; Association Ⅷ： Hypogymnia hypotrypella ＋ C. cetrarioides. （2） The similarity between association Ⅰ and association Ⅲ was the highest （0.321）, followed by association Ⅲ and Ⅳ （0.305）. Association Ⅱ and Ⅷ, association Ⅳ and Ⅷ had the lowest similarity （0.000）. Species diversity index of association Ⅲ was the highest （2.062）, followed by association Ⅴ （2.047）, and association Ⅱ （0.721）. Evenness index of association Ⅰ （0.809） was the highest, followed by association Ⅴ （0.802）, and association Ⅱ was the lowest （0.301）. （3） Species diversity of corticolous lichen in R. roxellana habitat of Shennongjia National Nature Reserve was mainly affected by humidity, temperature, illumination and altitude.
