中文摘要：

采用搜索采集法记载藏东南工布自然保护区的蚂蚁2亚科8属17种，切叶蚁亚科Myrmicinae有5属10种，蚁亚科Formicinae有3属7种，其中包括6个西藏新纪录种，1个中国新纪录种，5个待定种。工布自然保护区的蚂蚁物种属于古北界区系，但是又与典型的古北界区系不尽相同，具有南方高海拔山地的区系特点。在9个调查点中，错高乡的物种最丰富。在10类生境中，草地的物种最丰富。在8类栖息场所中，以石下筑巢的物种最丰富。高海拔山地蚂蚁对生境的选择与低海拔古北界地区物种不尽相同，获取太阳能的热量对它们的生存更为必要。

英文摘要：

Ant species and their distribution pattern in Gongbo Nature Reserve are investigated by the search-collecting method. 17 species belonging to 2 subfamilies and 8 genera are recorded in the nature reserve： 10 species and 5 genera belong to Myrmicinae, 7 species and 3 genera belong to Formicinae, including 6 new record species for Tibet, 1 new record species for China, and 5 species awaiting final identification. The ant species of the nature reserve belong to, but are not completely similar to the typical Palaearctic fauna, which have a southern alpine faunal character. Conggo town is the richest in species number among the 9 sites. Grassland is the richest in species number among the 10 vegetation types. Among the 8 habitats, most species nest under stone. Habitat selection of the alpine ant species is somewhat different from that of low altitude Palaearctic ones, where obtaining solar energy seems more essential for their livelihoods.
