【摘要】 以西双版纳勐仑自然保护区为对照 ,采用陷井诱捕法和样方调查法比较研究了 3个不同面积、不同环境状况的片断季节性雨林蚂蚁的群落组成及物种多样性变化。结果表明 :所获蚂蚁隶属 4亚科 2 4属 5 0种 ,以城子龙山物种数最多。各样地优势种均不相同。 4类样地间的共有物种较少 ,只有 4种 ;相似性较低 ,相似性系数在 0 162 2～ 0 3 5 4 8。聚类结果显示 ,植物园保护区与城子龙山最先聚为一类 ,然后与自然保护区聚为一类 ,最后才与曼养广龙山聚为一类。多样性指数以植物园保护区最高 ,自然保护区最低。更多还原

【Abstract】 This paper deals with the composition of ant communities and species diversity.Trap and sample plot were used in the investigation in the fragments of seasonal rain forest of different size and environmental status.The ants collected in the 4 spots belong to 4 subfamilies,24 genera and 50 species.The number of species in Chengzi Holly Hill was the highest.Dominant species in these spots were different.The common species were fewer and only 4 species appear in all the spots.The similarity of ant communities between plots was low and the coefficient was 0 1622-0 3548.A dendrogram constructed by the Jaccard index showed that similarity between Chengzi and Botanical Garden Reserve was the highest (0 3548).Species diversity indexes (H′) of ants in the Chengzi Holly Hill,the Manyangguang Holly Hill,the Botanical Garden Reserve and the Nature Reserve were 1 7771,1 6521,2 3785,0 9612 respectively.更多还原
