【摘要】 调查了无量山4个垂直地带21个样地7种植被类型的蚂蚁群落多样性,有5亚科19属41种蚂蚁在样地中表现为优势种,其中举腹蚁属为优势种最多的属,共有7个优势种,优势性最好的物种是巴瑞弓背蚁,分别在4块样地中都表现为优势种。总体上,无量山西坡的蚂蚁群落多样性明显优于东坡,北段的蚂蚁群落多样性优于南段;西坡与东坡、南段与北段的蚂蚁群落都属于中等不相似水平;各项重要群落指标在不同海拔高度上表现为明显"中部优、两头差"的垂直地带性分布规律,即海拔1 750 m样地最优,并在1 750 m基础上随海拔的升高和降低都逐渐变差;各项重要群落指标在不同植被类型中呈现思茅松林最优、河谷稀疏灌木草丛最差的特点。更多还原

【Abstract】 The composition of ant communities and species diversity in 4 vertical belts 21 sample plots 7 vegetation types of Wuliang mountain were investigated.The results showed that 41 species belonging to 19 genera of 5 subfamily were dominant species in its sample plots.Crematogaster had 7 dominant species,which had the most dominant species in all genera.Camponotus parius was the most widespread dominant species,which was represented as dominant species in 4 sample plot.Generally,the ant community diversity in west slope was obviously superior to those in east slope,and northern region better than southern region.The ant community in west slope and east slope showed medium dissimilarity,while in northern region and southern region was similar.The important community indexes in different altitude areas exhibited obvious vertical zonal distribution regularity that the diversity in central mountain superior to top and bottom mountain.The sample plot at 1 750 m altitude had the optimal diversity among all sample plots;and along with the altitude increasing and reducing,the diversity in sample plots gradually decreased.The important community indexes in Pinus kesiya sample plots were better than that in other vegetation types,and in valley sparse bushes were the worst.更多还原
