| 摘 要： | 为了揭示藏东南地区蚂蚁物种的分布规律,采用搜索调查法和样地调查法调查了德姆拉山西坡及波密河谷蚂蚁物种的分布格局。结果表明:发现蚁科(Formicidae)昆虫3亚科,10属,27种。其群落随生态环境条件的变化呈现带状分布;大多数物种对环境的适应性较弱,仅分布在低海拔区域,垂直分布高差小于500m;同一亚科不同属或同属不同种对环境的选择分化明显。在9类生境中,高山栎(Quercus semicarpifolia)林的物种最丰富;在9类觅食场所中,在地表觅食的物种最丰富;在6类筑巢场所中,在石下筑巢的蚂蚁物种最丰富。亮腹黑褐蚁(Formica gagatoides)是该地区分布最广泛、占据生境类型最多的物种。

| Abstract: | In order to reveal the distribution principle of ant species in southeastern Tibet,China,the distribution patterns of the ants from the west slope of Mount Demula and Bomi Valley were investigated by using sample-plot and search-collecting methods.In total,27 species belonging to 3 subfamilies and 10 genera of Formicidae were recognized.The data showed that the ant communities from the west slope presented certain zoning phenomenon with the change of ecological conditions;and most species had a weak adaptability to the environment and distributed only in low altitude areas,with the altitude difference less than 500m.In addition,the adaptabilities of different genus of the same subfamily and different species of the same genus to related environment were further differentiated.The ant species richness in Quercus semicarpifolia forest was the highest among the 9 types of habitats,and the species that foraged on the ground was the richest among the 9 types of foraging sites.Among the 6 types of nesting sites,those nested under stones were the most.Formica gagatoides was the most extensively distributed species in this area and occupied the widest range of habitats. |
