Abstract:

Amount, categories and distribution of soil fungi in the northern alp region of Hengduan Mountains were investigated, and the abundance(S), Shannon-wiener’s diversity index(H’), Pielou’s evenness(E) and dominance index(D) were calculated for community diversity of soil fungi. The results showed that the abundance(S), Shannon-wiener’s diversity(H′), Pielou’s evenness(E) and dominance index(D) were 6.7714±2.9415, 1.6956±0.4110, 0.9302±0.0719 and 0.2290±0.1052, respectively. Fungi quantity in Zheduo Mountain was the most, and the abundance(S) and Shannon-wiener’s diversity(H′) were also the most. They were 8.5000 and 1.8702, respectively. By means of Bray-Curtis Measure, soil fungi were vertically distributed from lower altitude upwards into 3 belts, i.e., mountainous region cold temperate zone and high-mountains subfrigid zone(altitude 2900~4400m)，high-mountains frigid zone(altitude 4400~4600m), and high-mountains frozen zone(altitude 4600~4800m).
