【摘要】 采用标准地调查和路线调查相结合的方法，我们在长白山、小兴安岭、大兴安岭主要针叶林内，对岳桦-云杉林等12个主要针叶林型的外生菌根真菌进行了调查。经对采集标本整理鉴定，计有19科43属163种外生菌根真菌。其中长白山18科39属135种；小兴安岭16科35属116种；大兴岭11科22属50余种。它们在各林型下的分布有一定的规律性，其种群组成和分布的多度与林木的组成、土壤和地形条件，如海拔高度、坡向和坡度等关系密切。更多还原

【Abstract】 With both plot cruising and route investigation methods, in Changbaishan Mountains, Daxing’an Ling Mountains and Xiaoxing’anling Mountains, We have investigated the ectomycorrhizal fungi in 12 main coniferous forest type, including Form. Picea, Abies-Betula ermanii. After arrangement and investigation on the specimens, 19 families, 43 genera and more than 163 species of ectomycorrhizal fungi were found. Among these specimens, there are 18 families, 39 genera and 135 species in Changbaishan Mountains, 16 families, 35 genera and 116 species in Xiaoxing’anling Mountains; and 11 families, 22 genera and over 50 species on Daxing’anling Mountains.Their distribution shows a certain regularity, it varies with the tree species, soils and topographic factors, such as altitube,aspects, slope position and steepness of slopes.更多还原
