摘　　要：以秦岭辛家山林区锐齿栎为研究对象,通过野外调查结合形态学和分子生物学方法,观察和鉴定与其共生的外生菌根真菌。结果确定了3种子囊菌和48种担子菌,分属于10科14属,其中毛革菌属Tomentella是优势类群,丝伞盖属1 Inocybe 1、Russula persicina、毛革菌属1 Tomentella 1、毛革菌属2 Tomentella 2、块菌属Tuber、绒盖牛肝菌属Xerocomus是常见种,其余都为稀有种。两样地锐齿栎外生菌根真菌除丰富度指数外,Simpson指数、Shannon指数以及Pielou均匀度指数差异不显著;Jaccard相似性指数和Sorenson相似性指数分别为0.1154和0.2069。A preliminary study on diversity of ectomycorrhizal fungi associated with Quercus aliena in Xinjiashan forest region of Qinling Mountains was investigated and observed using the combination of field investigation, morphological and molecular identification methods. The results showed that there were 52 different taxa of ectomycorrhizal fungi under 14 genera of 10 families, of these 48 taxa belonged to basidiomycetes, and 3 to ascomycetes. Tomentella was dominant; Inocybe 1, Russula persicina, Tomentella 1, Tomentella 2, Tuber and Xerocomus were common. The differences of Simpson index, Shannon index and Pielou evenness index of ectomycorrhizal fungi associated with Quercus aliena were not significant between site one and site two, except for differences of species richness. Jaccard index and Sorenson index were 0.1154 and 0.2069, respectively.
