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. 1200 m).
