摘要:

根据样方调查,对海南岛甘什岭无翼坡垒(Hopea reticulata)林群落的物种组成与物种多样性进行了分析。结果表明:(1)海南甘什岭无翼坡垒林群落有维管植物163种,隶属于64科128属,其中DBH≥1 cm的乔木有90种,隶属于40科66属;灌木有29种,隶属于17科24属;草本有21种,隶属于14科20属;DBH≥1 cm的木质藤本有25种,隶属于18科23属。(2)由物种分布频度分析可知,群落的建群种和优势种比例最低。(3)群落的Margalef丰富度指数为27.038,Shannon指数为3.647,Simpson指数为0.944,Pielou均匀度指数为0.716,生态优势度为0.054,与其他热带群落相比,该群落各项多样性指数均较低。(4)群落各层次的Margalef丰富度指数和Shannon指数表现为乔木层>灌木层>层间植物>草本层,Simpson指数和Pielou均匀度指数均表现为乔木层>层间植物>灌木层>草本层,生态优势度表现为草本层>灌木层>层间植物>乔木层。

Abstract: We used the plot investigation method to study the species composition and species diversity of a Hopea reticulata forest in Ganshiling Natural Reserve, Hainan Island. The results showed that: (1) 163 species in 128 genera and 64 families of vascular plants were recognized. A total of 90 tree species belonging to 66 genera and 40 families were identified and 25 species of rattans from 23 genera and 18 families were recorded. The shrubs contained 29 species, 24 genera and 17 families and a total of 21 species of herbs belonging to 20 genera, 14 families were recorded. (2) The proportions of dominant species and constructive species were low. (3) Compared with other tropical communities, the species diversity indexes of this community were relatively lower with the Margalef index of 27.038, Shannon index of 3.647, Simpson index of 0.944, Pielou evenness index of 0.716 and species dominance index of 0.054. (4) The Margalef index and the Shannon index of each layer of the community were in order of tree layer > shrub layer > liana layer > herb layer, and the Simpson index and the Pielou evenness index were in order of tree layer > liana layer > shrub layer > herb layer, while the species dominance index was in order of herb layer > shrub layer > liana layer > tree layer.
