皖大别山区虫生真菌群落多样性研究

摘要/Abstract

摘要： 选用物种丰富度(S)、ShannonWiener多样性指数(H')、Pielou均匀度(E)和优势度曲线(K-dominance)等指标,对安徽大别山区虫生真菌群落多样性进行了测定.结果表明,群落的多样性指标能较客观地反映群落的结构状态,揭示各群落间的关系.利用极点排序和系统聚类,可将安徽大别山区虫生真菌区系划分为3个垂直生态类群:温湿低山气候类型(海拔900m以下)、凉湿中山气候类型(海拔900～1200m)和寒湿山顶气候类型(海拔1200m以上).

关键词: 虫生真菌, 群落多样性, 安徽大别山

Abstract: The abundance,Shannon-Wiener's diversity index (H'),Pielou's evenness (E) and K-dominance curves were calculated for community diversity of entomogenous fungi in the Dabie Mountains.The results showed that the species number,diversity value,evenness and dominance were distinctly different among different habitats,altitudes,seasons and horizontals.These indexes reflected the community structure of entomogenous fungi,and revealed the relations among different entomogenous fungal communities.By means of Bray-Curtis Measure and UPGMA clustering analysis,entomogenous fungi were vertically distributed from lower altitude upwards into 3 belts,i.e.,warm humid low-mountains zone(alt.<900 m),cool humid mid-mountains zone(alt.900～1 200 m),and cold humid high-mountains zone(alt.>1 200 m).

Key words: Entomogenous fungi, Community diversity, Dabie Mountains in Anhui
