【摘要】 采用样地调查法,对哀牢山西坡4个垂直地带8种植被类型的土壤蚂蚁群落多样性进行调查。结果如下:共有74种土壤蚂蚁,其中42种为优势种;土壤蚂蚁群落多样性随海拔高度增加呈规律性的变化:优势种所占比例逐渐递增,优势种数目降低、物种数目递减、物种多样性指数降低;在8种植被类型中,土壤蚂蚁个体密度、优势种数量、物种数目、物种多样性指数、均匀度指数在思茅松林、针阔叶混交林和季风常绿阔叶林3种植被类型中较高,而在干性常绿阔叶林、半湿润常绿阔叶林、常绿阔叶苔藓矮林、河谷稀树灌木草丛和中山湿性常绿阔叶林4种植被类型中较低。更多还原

【Abstract】 The four vertical zones with eight different types of vegetations on the west slop of Ailao mountain was sampled for studying community diversity of the soil ants.The results were as follows:The total number of soil ants was 74 species,among which there were 42 dominant species.There was a correlation of soil ants diversity with increasing elevation.The percentage of dominant soil ants species in the total soil ants species increased,while dominant individual density,species number and diversity index of soil ants decreased.In eight different vegetations,individual density,dominant species number,species number,diversity index and evenness index of soil ants were higher in Pinus kesiya forest,monsoon evergreen broad-leaved forest and mixed coniferous forest than those in dry evergreen broad-leaved forest,semi-humid evergreen broad-leaved forest,evergreen broad-leaved moss forest,valley savanna forest and mid-mountain humid evergreen broad-leaved forest.更多还原
