摘要/Abstract

摘要： 木材腐朽菌是森林生态系统的重要组成部分,在森林生态系统中起着极为重要的降解还原作用,主要包括担子菌门非褶菌目、子囊菌门盘菌纲和半知菌类的部分真菌,能全部或部分降解木材中的木质素、纤维素和半纤维素,其降解机制有3种:白色腐朽、褐色腐朽和软腐朽.木材腐朽菌与生态系统中其它生物关系密切,为很多昆虫、鸟类提供营养,有些昆虫也能使木腐菌得到传播.保护木材腐朽菌的生物多样性是保护森林生态系统、维护生态系统健康的重要因素.

关键词: 木材腐朽菌, 森林生态系统, 生态功能

Abstract: Wood-inhabiting fungi are one of the most important parts of forest ecosystem,and play an important role in degrading the wood in forest ecosystem.The major species of these fungi include the groups of Aphyllophorales (Basidiomycota),Discomycetes (Ascomycota) and some imperfect fungi.They have the ability to degrade cellulose,hemicelluloses and lignin of wood.Three type of wood decaying have been found,i.e.,white rot,brown rot and soft rot.Many other organisms of forest ecosystem have symbiosis relationship with wood-decaying fungi.Wood-inhabiting fungi could offer the nutrition for many insects and birds,and spores of many wood-rotting species are spread by some insects.The high biodiversity of wood-decaying fungi is one of the important factors for the health of forest ecosystem.

Key words: Wood-inhabiting fungi, Forest ecosystem, Ecological function
