本文对内蒙古大青沟自然保护区内的真菌区系进行了多样性分析。结果:含10种以上的科为口蘑科、革盖菌科、丝膜菌科、蘑菇科、球盖菇科、蜡伞科和炭角菌科;含5种以上的属为丝盖伞属、小皮伞属、多孔菌属、鳞伞属、光柄菇属、炭角菌属、蘑菇属、赤褶菌属、蜡伞属、湿伞属、靴耳属、囊蘑属、栓菌属和马鞍菌属;从种的组成上可划分为世界分布种(34.11%)、北温带分布种(42.05%)、北温带-澳大利亚分布种(5.30%)、温带-亚热带、热带分布种(3.31%)、欧亚大陆分布种(2.98%)、东亚-北美间断分布种(2.32%)、东亚分布种(1.97%)、中国-日本共有种(4.64%)和特有成分(3.97%)等9个分布型,表现出鲜明的温带区系特征。在区系亲缘关系上与长白山较为接近,而与热带、亚热带的区系较为疏远。

The result of the flora diversity study indicated that there were rich fungal flora in the Daqinggou Nature Reserve in Inner Mongolia of China. The dominant families are Tricholomataceae ,Coriolaceae ,Cortinariaceae , Agaricaceae ,Strophariaceae , Hygrophoraceae and Xylariaceae , while the dominant genera are Inocybe , Marasmius , Polyporus , Pholiota , Pluteus , Xylaria , A garicus , Rhodophyllus , Hygrophorus , Hygrocybe , Crepidotus , Melanoleuca , Trametes and Helvella. Regarding the composition , the species were grouped into : Cosmopolitan (34. 11 %) , North Temperate Zone (42. 05 %) ,North Temperate-Australia (5. 30 %) , Temperate- subtropical or Tropical (3. 31 %) , Eurasian (2. 98 %) , Eastern Asia-North America (2. 32 %) , Eastern Asia(1. 97 %) , Sino-Japan in common(4. 64 %) , and endemic(3. 97 %) . In all nine distributional types , cosmopolitan and North Temperate Zone are characteristics of this region. The fungal flora of Daqinggou is very similar to that of the Changbai Mountains in Northeast China. This suggests that the origins of these two floras may have a certain relationship , but they have no close relationship with the fungal flora in subtropical and tropical regions.
