摘　　要：2004至2007年,对广西主要林区的多孔菌进行了初步调查采样,鉴定出广西地区的多孔菌15科,58属,136种,其中新记录种84种,占该地区所报道种的61.8%;种类组成分析显示,优势科为多孔菌科Polyporaceae(45.6%),优势属为多孔菌属Polyporus(8%);属的地理成分以热带?亚热带分布属(25.9%)为主(除世界广布种),种的地理成分以泛热带分布成分(38.2%)为主。在区系分析中广西与海南的关系较为接近,表明两者在区系有亲缘关系。Guangxi Auto Region was one of region with rich resource of wood-decaying fungi in China.Investigations on wood-decaying fungi had been carried out in the main forest ecosystems of Guangxi during 2004-2007.After systematic study on morphological characters,136 species of wood-decaying fungi were identified,belonging to 58 genera in 15 families.Among 84 species（up to 61.8 % of total species） are new in Guangxi.The study showed that the dominant family was Polyporaceae（45.6 %）,and the dominant genus was Polyporus（8 %）.Except cosmopolitan element,tropical-subtropical elements（25.9 %） played an important role on the genera level;on species level,the tropical elements（38.2 %） were dominant.The wood-decaying fungi flora of Guangxi was very similar to that of Hainan province in tropical China.This suggested that the polypore flora of two areas were closely related.
