摘　　要：通过样地法比较了高阿丁枫、马尖相思、马尖相思 + 西南桦三种人工林群落林下植物的生活型谱。结果发现,三种类型都以高位芽植物为主,其次为地面芽植物;在高位芽植物中又都以小高位芽植物比例较高;其叶型谱以中型叶为主。生活型谱和叶型谱都与热带南亚热带的群落相似。The life form spectrum, leaf size spectrum of understory plants of Altingia excelsa, Acacia mangium pure forest and Acacia mangium + Betula alnoides mixed forest in tropical mountain were studied by using plot method (quadrat investigation method). The results showed that Phanerophytes was the dominant life form in three types. The percentage of Miphanerophytes was the highest in the Phanerophytes. The dominant leaf size of the three kinds of forests was Mesophyll.
