摘　　要：为调查长春地区黏菌资源的物种多样性,便于掌握长春地区黏菌资源情况,对长春地区的黏菌进行了为期3年的系统调查,共采集到标本2,000余份,通过形态特征鉴定为5目7科23属59种。团毛菌科、绒泡菌科和发网菌科为优势科,共计49种,占长春地区黏菌总种数的83.1%,科的数目占总科数的42.8%。团网菌属、半网菌属、团毛菌属、绒泡菌属和发网菌属为优势属,共计34种,占总种数的57.6%。从种的组成上可以划分为世界广布种(67.8%),北温带分布种(10.17%),东亚-北美洲间断分布种(5.08%),温带-亚热带、热带间断分布种(10.17%),北温带-南温带间断分布种(5.08%),中国分布种(1.69%)共6个分布型,表现出明显的温带区系特征,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。More than 2,000 specimens of myxomycetes were collected from Changchun in 2008-2010.Fifty-nine species were identified,belonging to 23 genera of 7 families in 5 orders.Trichiaceae,Physaraceae and Stemonitaceae were dominant families with 49 species in all accounting for 83.1% of the total species.Arcyria,Hemitrichia,Trichia,Physarum and Stemonitis were dominant genera,and totaled 34 species accounting for 57.6% of the total species.At the species level,the myxomycetes in Changchun could be classified into the following distribution types：cosmopolitan（67.8%）,North temperate（10.17%）,East Asian-North American（5.08%）,Temperate-subtropical or tropical species（10.17%）,North temperate-South temperate（5.08%） and endemic in China（1.69%）.The flora is very close to that of the Changbai Mountains,while it has no close relationship with the flora in subtropical and tropical regions.
