贵州百里杜鹃国家森林公园土生和石生苔藓植物比较研究

Comparative Studies on Earth- and Rock-type Bryophytes in Baili Azalea National Forest Park,Guizhou

摘要:

对贵州百里杜鹃国家森林公园的土生型和石生型苔藓植物的物种多样性进行比较研究，结果表明：两种基质上共有苔藓植物17科34属57种，其中土生型17科27属35种，石生型10科12 属19种，兼生型3种。土生型与石生型苔藓植物的种相似性系数为0.22，Shannon-Wiener指数和种间相遇机率指数均较低，Simpson指数较高，表明百里杜鹃国家森林公园苔藓植物的种类分布显著受基质影响。

Abstract:

The diversities of earth- and rock-type bryophytes in Baili Azalea National Forest Park, Guizhou Province were studied. The results showed that there were 57 species bryophytes, belonging to 34 genera and 17 families, in which 35 earth-type species to 27 genera and 35 families, and 19 rock-type species to 12 genera and 10 families, 3 species facultative. The species similarity coefficient between two types was 0.22. Probability of interspecific encounter index and Shannon-Wiener index were low, while Simpson index was relatively high. It suggested that the bryophyte distribution in Baili Azalea National Forest Park was significantly influenced by substrates.
