中文摘要：

利用样地调查法对哀牢山自然保护区西坡4个垂直带、8个水平带的28块样地140个样方的蚁科昆虫进行了调查，结果表明：群落的物种丰富度随海拔的升高、气温的降低和植被的减少而减少，蚂蚁群落随着生态环境条件的变化而出现一定的分带现象；特有种的数量随着海拔高度的增加而降低，类型组成则随海拔的增加而由杂食性、肉食性、植食性逐渐变为植食性，预示栖息环境的植被逐渐稀少、食物资源变得贫乏；尽管西坡同一海拔植被类型相似，但是蚂蚁群落之间差异显著。样地的34组相似性系数中，有4组相似性系数处于0．25～0．50之间，为中等不相似水平，占11．8％，其余30组为极不相似水平或无任何相似，占88．2％，表明保护区的蚂蚁群落具有显著的垂直地带性特点。

英文摘要：

This paper deals with the ants＇ community in Mt. Ailao based on the investigation method of sample plot. Numerically, 140 sample plots in 28 sample stands along 8 vertical vegetations at 4 different sections on west slope were investigated. Results are as follows： the ant species composition is closely related to elevation, air temperature and forest cover, and the ant richness decreases with elevation increasing and temperature and forest cover decreasing; the ant community prefers to live in a special belt due to the changing ecological environment conditions, which is mostly influenced by the heterogeneity of their habitat and their biological characteristics. The number of endemic species decreases while elevation increasing. The ant community at low elevation is made up of omnivorous, carnivorous, phytophagous types. At high elevation, there is only phytophagous type, indicating that the vegetation decreases gradually and food resources are getting scarce with increasing elevation. Although the similar vegetation type at the same contour on the west slope, ant communities have distinct differences with similarity coefficients from 0 to 0.50. In a total of 34 similarity coefficients, most are within 0 and 0.25, representing an extremely dissimilar level, while only 4 of them range from 0.25 to 0.50, representing a moderate dissimilar level, which shows an obvious characteristic of vertical zonality.
