中文摘要:

为了全面揭示云南蚂蚁多样性规律，采用样地调查法研究了滇东南地区的蚂蚁物种多样性。结果表明：在滇东南地区5个垂直带共采获蚂蚁7亚科57属202种；各样地蚂蚁群落主要指标为：物种数目6~49种（平均24种），个体密度0.7~5 943.6头/m2（平均560.5头/m2），多样性指数0.1693~2.6382（平均1.6574），均匀度指数0.0771~0.8022（平均0.5468），优势度指数0.0012~0.9031（平均0.2733）；蚂蚁群落间相似性系数0.0333~0.3810，处于极不相似至中等不相似水平。结论认为，滇东南地区栖息着丰富的蚂蚁种类，在生态系统功能和生物多样性保护中具有重要价值。垂直带上蚂蚁物种的丰富度和多样性主要受气温制约，具体表现为纬度和海拔对蚂蚁群落的影响。该地区蚂蚁群落主要指标普遍表现出多域效应现象，除了地形和森林结构因素外，主要受到人类干扰影响，应当结合天然林保护工程对该地区蚂蚁群落加以保护，以便充分发挥其生态功能。

英文摘要:

In order to reveal ant diversity regularity in Yunnan, ant species diversity of Southeastern Yunnan was surveyed through sample plot method.The results showed that 202 species belonging to 57 generaand 7 subfamilies were recognized on the 5 vertical zones in the area.Main indexes of ant communities from different sample plots were as follow: species numbers 6~49 (average 24), individual densities 0.7~5 943.6 heads/m2 (average 560.5 heads/m2), diversity indexes 0.1693~2.6382 (average 1.6574), evenness indexes 0.0771~0.8022 (average 0.5468), dominant indexes 0.0012~0.9031 (average 0.2733); similarity coefficients between ant communities 0.0333~0.3810, which representing extremely dissimilar to moderately dissimilar level.It was concluded that there were rich ant species living in southeastern Yunnan, which had important value in ecosystem function and biodiversity conservation.Ant species richness and diversity on the vertical zones were mainly restricted by air temperature, and concretely expressing as the influence of latitude and altitude on ant communities.The main indexes of ant communities of the area commonly express multi domain effect phenomenon, besides the factors of landscape and forest structure, it is mainly influenced by human disturbance.It ought to protect ant communities of the area combing the natural forest protection project, so as to give full play of ecosystem function of the ants.
