研究了南京紫金山大型真菌的区系成分和生态分布,以期为开展大型真菌在紫金山生态系统中的作用研究打下基础.通过2 a的实地调查,共获得大型真菌290种,分属于子囊菌和担子菌的49科120属.按所处植被环境划分,紫金山大型真菌可分为常绿-落叶阔叶昆交林型、针阔混交林型、针叶林型、竹林型和灌丛荒地型；按营养类型划分,主要分为土生菌(151种)、木生菌(151种)、外生菌根菌(49种)和虫生菌(2种)等；按区系组成划分,可分为世界广布种(该分布种种数占总种数的比例为18.97％)、北温带分布种(36.89％)、北温带-澳大利亚分布种(13.45％)、温带-亚热带或热带分布种(7.59％)、欧亚大陆分布种(5.86％)、东亚-北美间断种(5.17％)、中国-日本共有种(2.07％)和中国特有种(10.00％).%In order to lay down a solid basis for the study on ecological function of the macrofungi in the Zijin Mountain e-cosystem, species composition and ecological characteristics of the macrofungi were investigated and analyzed. Through a two-year field investigation, a total of 290 species of macrofungi were recorded, belonging to 120 genera of 49 families. The habitats they were found in could be sorted into types of evergreen-deciduous broadleaf mix forest, coniferous-broadleaf mix forest, coniferous forest, bamboo groves, and shrubby wasteland. By trophic type, they could be grouped into ligni-colous (151 species) , entomophilous (151 species) , and ectomycorrhizal (49 species) , and entomogenous species (2 species). By floral composition, they could be classified into the following distribution types, i. e. Cosmopolitan (18.97%), North Temperate (36.89%), North Temperate-Australia (13.45%), Temperate-subtropical or Tropical (7.59%), Eurasian (5.86%), Eastern Asia-North America (5.17%), China-Japan (2.07%), and China (10. 00% ).
