采用样方法,对湖南紫金山马尾松群落的种类组成、群落外貌、结构特征及物种多样性进行了研究。结果表明:在1 200m2样地中,共有维管束植物41种,隶属于25科38属,其中优势科主要有樟科、山茶科、豆科、大戟科及蔷薇科等;该群落是以马尾松为主的单优种群落,生活型谱以高位芽植物最多,群落季相明显;群落分层明显,可划分为乔木层、灌木层、草本层和层间植物;灌木层植物种类相对较丰富,对群落物种多样性具有较大影响,物种多样性的大小顺序依次为灌木层>乔木层>草本层。

The characteristics and species diversity of Pinus massoniana community were studied based on community investigation.Results show that： 41 species in 38 genera and 25 families of vascular plants were recorded in 1 200 m2 plots,in which the dominant families are Lauraceae,Theaceae,Leguminosae,Rosaceae.Phanerophytes are the largest in number of all species in the community according to Raukiaer＇s statistics of life form.The aspection of the forest community is distinct all the year round.The layered phenomena is very obvious of Pinus massonian...
