Abstract: Soil fungal diversity and the relationship between physical and chemical properties were studied using 454 high-throughput sequencing under bare land, Tamarix chinensis community and Apocynum venetum community. Total of 174 genera and 5 phyla were obtained in this study. The species and diversity of these fungi in different soil samples were different. Many kinds of fungi were obtained in A. venetum community, and HZ3A had the most fungi species. The genus of HZ3A was 2.23 times as much as HZ1A, 1.74 times as much as HZ1B, 1.24 times as much as HZ2A, 2.18 times as much as HZ2B, 1.38 times as much as HZ3B. In addition, soil fungal diversity of A. venetum community was higher than those of bare land and T. chinensis community. Alkali-hydrolyzable nitrogen (AN) had the greatest impact on distribution and diversity of soil fungal genera. AN was negatively correlated with the relative abundances of Knufia, Cochliobolus, Mucor, Malassezia and was positively correlated with the other fungi.

Key words: Yellow River Delta, 454 high throughput sequencing, soil fungi, fungal diversity, alkali-hydrolyzable nitrogen
