摘　　要：采用样地调查法研究了梅里雪山东坡海批250～3250m的蚂蚁群落．共采集蚂蚁1704头，隶属于3亚科12属21种，其中包括13个已知种，8个待定种．研究发现：梅里雪山东坡蚂蚁区系是东洋界与古北界成分的混合体，但以东洋界成分占主导地位．从调查地多样性指标看，山体上部物种多样性最高，山体中下部多样性较低，山脚干暖河谷多样性最低．从蚂蚁群落相似性系数来看，梅里雪山东坡垂直地带性差异显著，蚂蚁群落之间的相似性极低．从生物多样性保护角度来看，梅里雪山东坡3000m及其以上区域保持着自然状态，尚未受到明显干扰；2750m及其以下区域已经受到当地居民和旅游业的明显干扰，其中2500m附近区域受到人类影响最为直接．The ant communities on the east slope of the Meili Snow Mountain between 2 250 m and 3 250 m in elevation were surveyed for the first time by means of plot investigation method. Totally 1 704 ant samples were collected, which belonged to 21 species, 12 genera and 3 subfamilies. Among which 13 were known species and 8 were unknown ones. It was showed that the ant fauna of the Meili Snow Mountain was a mixture of Oriental and Palearctic compositions, being dominated by the Oriental composition. According to the diversity index analyses, the highest species diversity was found at the upper slope, the lower indexes appeared at the middle and low portions of the east slope, and there was the lowest species diversity in the dry warm valley at the foot of the mountain. In the light of the similarity coefficients of the ant communities, it was concluded that there was distinct divergence among the vertical zones on the east slope, i. e. , the similarity among the studied ant communities was extremely low. Based on the status of biodiversity conservation, it was indicated that the area above 3 000 m in elevation on east slope of the Meili Snow Mountain basically remained the natural status, the area below 2 750 m had been significantly disturbed by local people and tourism activities, and the strongest anthropogenic disturbance was observed around 2 500 m in the dry warm valley.
