| Abstract: | To understand the soil fungal community diversity in different zones of the Zoige Alpine Wetland, BIOLOG analysis and traditional culture method were employed in our research. Three sample sites namely the Conservatory Station up-hill slope (CSUS), the Flower Lake side (FLS) and the Conservatory Station down slope (CSDS) with increasing by water content were investigated. The results of BIOLOG showed that fungal catabolic richness index (S) and Shannon diversity index (H) increasingly rose with water content augmented from CSUS to CSDS, while different from the former tendency, the fungal catabolic activity was highest at CSDS and lowest at FLS. Principal component analysis (PCA) results demonstrated the functional diversity of fungal community varied among the three sample sites, showing us more similarity between CSDS and FLS, and considerable difference between CSUS and the former two sites. The outcome of traditional culture method illustrated the number of soil fungi increased from CSUS to CSDS, while the sort of fungal species that could be cultured did not show much difference among the three sample sites. |
