摘  要：
运用样地调查法对哀牢山自然保护区西坡4个垂直地段28块样地140个样方中的蚂蚁进行调查,共采集蚂蚁标本57 345号,分属9亚科49属172种.切叶蚁亚科的毛切叶蚁属L asiomy rm ex T erayam a etY am ane为中国新记录属.优势亚科为切叶亚科、蚁亚科、猛蚁亚科、臭蚁亚科,优势种有43个.优势种数目随地段或海拔的变化缺乏一致的规律性,优势种百分比随海拔变化有一定的规律.在海拔2 000 m(北段1 750 m)处及以上海拔,蚂蚁群落均由1~3种蚂蚁占绝对优势,甚至只包含1~2种蚂蚁.2 000 m以下蚂蚁优势种数目增加或优势百分比降低.此外,讨论了哀牢山与太白山蚂蚁物种丰富度差异大的原因.

摘  要：
Using a sample-plot investigation method,this paper makes a study of ants' species composition and their dominant species in Mt.Ailao.Numerically,140 sample plots in 28 sample stands along vertical vegetations at 4 different sections on its west slope were investigated.Totally,172 species belonging to 49 genera and 9 sub-families were recorded.A new genus record in China is Lasiomyrmex Terayama et Yamane,Myrmicinae.The dominant subfamilies are four: Myrmicinae,Formicinae,Ponerinae and Dolichoderinae.The total number of dominant species is 43;their number per sampl plot is normally changed from 1 to 3.There are six dominant species in Pinus kesiya forest at the elevation of 1 250 m in the north section,followed by five in monsoon evergreen broad-leaved forest at the elevation of 1 750 m in the south-middle section,four in Pinus kesiya forest at the elevation of 1 750 m in the north-middle section.The number of dominant species is not related to section or elevation but their percentage is related to different elevations.Normally,there are 1～3 dominant species in each sample stand above the elevation of 2 000 m at the south,middle-north,middle-south sections,and above 1 750 m at the north section.Below the elevation of 2 000 m,its number increases or percentage decreases.As a furtherance,the paper also discusses the causes for the number difference of ant species between Mt.Ailao and Mt.Taibei.
