In the study, the experiment with nitrogen addition treatment and litter management were carried out in Larix principis-rupprechtii plantation of Yin Mountains. The short-term effects of fungal community composition, diversity and function in surface soil (0～10cm) were analyzed by high-throughput sequencing technology. The interaction of nitrogen addition and litter management were studied. The results showed that nitrogen addition and litter management significantly increased the relative abundance of Ascomycota, but the relative abundance of Basidiomycota was significantly reduced. Nitrogen addition significantly increased the relative abundance of Amphinema, with high nitrogen being the largest was 10.15%. Litter management significantly increased the relative abundance of Choiromyces, Helvella and Mortierella, with the largest amount in gathering management were 11.03%、13.57% and 6.36%. The two treatments significantly increased the Shannon index and Simpson index of soil fungi, with the largest amount were 6.41, 5.77 and 0.96, 0.94 in high nitrogen and mixing. Nitrogen addition and litter management significantly reduced the relative abundance of Symbiotroph. Soil pH and nitrate nitrogen content are the main factors affecting soil fungal community. The contents of soil available phosphorus, available potassium, nitrate nitrogen, the number of OTU, alpha diversity index, and the relative abundance of Saprotroph in high nitrogen and mixing measure were all the highest. The research results played an important role in promoting the decomposition of litter and maintaining the balance of soil fertility.
