摘　　要：通过开展巨尾桉(Eucalyptus grandis×Eucalyptus urophylla)、马尾松(Pinus massoniana Lamb.)2种人工纯林群落的物种多样性研究,结果表明:2种不同类型人工林在立地条件较好的林分,植物物种多样性指数较高,反之较低;立地条件相似的2种不同类型人工林,其物种多样性指数差别不大;2种不同类型人工林灌木层的Shannon-Weiner指数、物种丰富度指数都高于草本层,但物种多样性指数差别不大;2种不同类型人工林下物种多样性取决于该立地原有的生物种类和抚育措施。巨尾桉作为扶绥县主要造林树种,人工林下物种多样性比较丰富。The species diversity of two pure plantation communities of Eucalyptus grandis and Pinus massoniana were studied. The results showed that the diversity index of plant species was higher in two different types of plantations with better site conditions,and vice versa,and the species diversity index of the two different types of plantation with similar site conditions was not significant;the Shannon-Weiner index and the species richness index of the two different types of plantation shrubs were found. It is higher than the herb layer,but the species diversity index is not very different;the species diversity under two different types of plantations depends on the original species and tending measures of the site. Eucalyptus grandis（Eucalyptus urophylla）is a main tree species for planting in Fusui county.
