摘　　要：应用样方调查方法分析了贵州省纳雍县、麻江县和台江县的3个十齿花Dipentodon sinicus群落的物种组成及群落结构,结果表明:(1)3个群落共有维管植物56科65属88种,其中,蕨类植物7科、裸子植物2科、被子植物47科;(2)根据主要的优势树种把3个群落分为十齿花+杉木+马尾树群落,栲树+十齿花群落和华山松+十齿花+茅栗群落;(3)3个群落中各个生活型类型所占的比例大致相同,同一群落中高位芽植物所占比例最大,一年生植物所占的比例最小;(4)3个群落的成层现象均非常明显,基本上可以分为乔木层、灌木层和草本层3个层次;(5)群落物种多样性水平从高到低的顺序是:台江>麻江>纳雍。In this paper, the species composition and structures of 3 D. sinicus communities in Nayong,Majiang and Taijiang county of Guizhou were studied by sampling. And the results showed that： （1） To-tally, 88 species of 56 families （7 of Pteridophyte, 2 of gymnosperm and 47 of angiosperm） and 65 generawere recorded in the 3 communities; （2） According to the dominated species, the 3 D. sinicus communitieswere divided into D. sinicus q- Cunnighamia lanceolata q- Rhoiptelea chiliantha community, Castanopsishystrix -/- D. sinicus community and Pinus armandi q- D. sinicus q- Castanea seguinii community; （3）The proportion of each life form was roughly similar in the three communities. The proportion of phanero-phytes was the largest in the same community, and that of therophyte was the least; （4） The stratificationof the 3 communities was obvious, and all could be divided into 3 layers： tree layer, shrub layer and herblayer; （5） The order of the species diversity level from high to low is： Taijiang Majiang Nayong.
