One hundred and eight isolates of soil dematiaceous hyphomycetes belonging to 15 genera were found from 59 soil samples collected in central and western of Qaidam Basin covered with desert, gobi, swamp and town-oasis. The species dominance, Shannon-Wiener index, evenness and niche width were used to study the diversity of soil dematiaceous hyphomycetes in different ecosystem of Qaidam Basin. The results showed that the species dominant in the four ecosystem types was distinctly different. In desert ecosyste...
