Abstract: The purpose of the paper was to study the effect of plants planting on fungal diversity and nutrients in reclaimed soil in the coal gangue landfill area, and to provide theoretical basis for improving the quality of reclaimed soil. Compared with that of natural restoration, the reclaimed soil planted with maize, soybean, alfalfa and hair-vetch was the characteristics of fungal diversity in reclaimed soil and its correlation with soil nutrients were analyzed based on high-throughput sequencing technology. The results showed that the Simpson index of fungal diversity was the largest under soybean, which was significantly higher than that under natural restoration (P<0.05); Shannon index was larger under soybean and maize, and the difference was not significant, but was significantly higher than that under natural restoration (P<0.05); Chao1 index and ACE index were the largest under hair-vetch, which was not significantly different with maize and soybean, but significantly higher than natural restoration (P<0.05).The number of OTU units under different plants(514-732) was higher than that under natural restoration(439). The higher abundance of fungi phylum in reclaimed soil was ascomycota, and the higher abundance genus was mortierella. There were significant differences under different plant planting in reclaimed soil, including 1 Class, 7 Orders, 11 Families, and 7 Genera.In addition to TP and TK, the contents of TN, OM, AN, AP and AK in the reclaimed soil were the lowest under natural restoration, and the contents of TN, OM and AN in the soil between natural restoration and plant planting were significantly different, which were the highest under hair-vetch treatment. The results of RDA showed that TN, TP and AN were the main nutrient factors driving the change of fungal diversity in the reclaimed soil. In general, planting plants could improve the nutrient content of reclaimed soil, change the structure of fungal community and increase the diversity of fungi in reclaimed soil.
