| 摘 要： | 为揭示喜马拉雅山蚂蚁群落的生态学规律,采用样地调查法对喜马拉雅山底雅段和札达段的蚂蚁群落进行调查。共观察蚂蚁5355头,隶属于2亚科5属7种,其中底雅段7种,札达段3种。对该地区蚂蚁物种丰富度进行估计,结果表明底雅段和札达段的蚂蚁物种丰富度较低。底雅段南坡的蚂蚁物种数目、Shannon-Wiener多样性指数、Fisherα指数和优势度指数表现出"中域效应"现象,而个体密度则表现出"多域效应"现象;札达段南坡的蚂蚁物种数目、个体密度和Fisherα指数均表现出"多域效应"现象。蚂蚁群落相似性系数显示各样地间的蚂蚁群落处于极不相似至极相似水平,表明该地区不同海拔蚂蚁群落既有差异又存在一定共性。在底雅段和札达段,海拔对蚂蚁物种的分布和多样性有较大影响,坡向和植被对蚂蚁群落分化有重要作用。

| Abstract: | To clarify the ecology of ant communities of Himalayas,communities from the Diyag and Zanda sections were investigated using a sample-plot method.In total,the 5355 individuals comprised 7 species belonging to 2 subfamilies and 5 genera of Formicidae.There were 7 species in Diyag section and 3 species in Zanda section.Ant species richness was estimated,the species accumulation curves revealed relatively lower ant species richness of the Diyag and Zanda sections.Ant species numbers,ShannonWiener diversity indices,Fisherαindices,and Simpson index on the south slope of the Diyag section displayed a"mid-domain effect"phenomenon,while the individual density displayed a"multi-domain effect"phenomenon.Ant species numbers,individual densities,and Fisherαindices on the south slope of the Zanda section displayed a"multi-domain effect"phenomenon.The similarity analysis revealed a marked dissimilarity of the ant communities among the samples,indicating the existence of differences and similarities in the ant communities along an elevational gradient in this area.The distribution of ant species and diversity were mainly influenced by altitude,while slope direction and vegetation type were important in ant community differentiation. |
