摘　　要：采用样方法对西双版纳加勒比松人工林开展了群落学调查。结果表明:(1)加勒比松人工林有维管束植物43种,分属22科41属;(2)乔木层、灌木层和草本层的的香农威纳指数分别为2.71、1.52和2.69;(3)其群落垂直结构明显,可分为乔木层Ⅰ层、乔木层Ⅱ层、灌木层和草本层4层;(4)加勒比松人工林群落的物种丰富度和乔灌层的多样性指数低于天然次生林,而群落垂直结构较天然次生林复杂。Community characteristics of the Pinus caribaea plantation was investigated by using the plot sampling method in Xishuangbanna. The results showed that： （1） there were 43 species of vascular plants belonging to 41 genera and 22 families in the Pinus caribaea plantation; （2）Shanon-Weiner inde- xes of its tree layer, shrub layer and herb layer were 2.71,1.52 and 2.69 respectively;（3 ） The vertical structure of the community could be divided into tree layer I , tree layer Ⅱ , shrub layer and herb layer clearly; （4） Species richness and diversity index of tree layer and shrub layer were all lower than those of natural secondary forest, while its vertical structure was more complex as compared with the secondary for- est.
