摘　　要：金钱松是现存松科植物的原始类群,是受国家II级保护的珍稀树种。采用样方法,对湖南南岳衡山金钱松群落的种类组成、群落外貌、结构特征及物种多样性进行了研究。结果表明:在1 200 m2样地中,共有维管束植物47种,隶属于35科44属,其中优势科主要有樟科、杜鹃花科、豆科、大戟科及蔷薇科等;该群落是以金钱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、草本层和藤本层;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>草本层>藤本层>乔木层。The characteristics and species diversity of Pseudolarix amabilis community were studied based on community investigation. The results show that 47 species in 44 genera and 35 families of vascular plants were recorded in 1 200 m2 plots, in which the dominant families were Lauraceae, Ericaceae, Compositae, Euphorbiaceae and Rosaceae, the community was the largest consociation that P amabilis predominated the forests, the community＇s life-form spectrum showed that the phaenerophyta accounted for the major parts, the aspection was obvious; the stratification of the forests was very obvious, which can be divided into tree, shrub, herbaceous and liana layer; the shrub layer was relatively abundant in species and had a greater effect on the community diversity, the diversity indexes for every forests ordered from high to low： shrub, herb, liana and arbor.
