2013年7—9月,以清原林场、老秃顶子国家级自然保护区和宽甸白石砬子自然保护区为研究区域,对辽东次生林中木腐菌的物种多样性及其分布特征进行了研究.经过野外调查,共采集和记录木腐菌1062份,经鉴定为92种,隶属于48个属;其中白石砬子国家级自然保护区木腐真菌物种最丰富,Shannon多样性指数为4.04.从物种的地理成分来看,辽东地区的木腐菌以世界性广布和北温带分布为主,具有明显的北温带特征.白腐真菌是该地区倒木的主要分解者;该地区的木腐菌主要生长在腐烂等级为2、3的倒木上,主要优势寄主为槭属倒木,有243份真菌采集于槭属倒木,占总数的23.2%.
From July to September 2013, the species diversity and distribution of wood rot fungi in the secondary forest of Liaodong were studied using Qingyuan Forest Farm, Laotudingzi National Nature Reserve and Kuandian Baishijiazi Nature Reserve as the research area. After field investigation, a total of 1062 wood fungi were collected and recorded, of which 92 species were identified, belonging to 48 genera. Among them, the species of white rot fungi was the most abundant in Baishigutangzi National Nature Reserve, with a Shannon’s diversity index of 4.04. , The wood rot fungi in Liaodong area are mainly distributed in the world and the north temperate zone with obvious north temperate features.The white rot fungus is the main decomposer of the fallen wood in this area.The wood rot fungi in this area are mainly Growing on the fallen wood with decay rating of 2 and 3, the main dominant host was fallen maple, and 243 fungi were collected from fallen maple, accounting for 23.2% of the total.
