In order to understand the variations of soil faunal diversity under different natural alpine vegetations in West Sichuan, an investigation was made on the soil faunal communities under alpine coniferous forest, shrub, and meadow from August 2008 to June 2009. A total of 48343 individuals were collected, belonging to 7 phyla, 16 classes, 31 orders and 117 families. There was a great difference in the dominant groups of soil macro-fauna, and a significant difference (P < 0.05) in the number of soil faunal groups under different vegetations. Both the individual density and the group number of soil fauna decreased obviously with increasing soil depth, and were significantly higher (P < 0.01) in moss layer than in litter layer in coniferous forest. Significant difference (P < 0.01) was also observed in the density-group index among the three vegetations. The maximum biomass of soil macro-fauna was found in June. Jacard indices indicated that disturbed meadow had the lowest similarity of soil faunal community with the other vegetations. It was suggested that vegetation type had significant effects on the community structure of soil fauna, while aspect, altitude, and disturbance also had definite effects.
为了解川西不同天然高山植被下土壤动物多样性的变化，于2008年8月至2009年6月对高山针叶林、灌丛和草甸下的土壤动物群落进行了调查。共采集到48343个个体，隶属于7门、16纲、31目和117科。土壤大型动物的优势类群存在很大差异，不同植被下土壤动物类群数量也存在显著差异（P<0.05）。土壤动物的个体密度和类群数均随土壤深度增加而明显降低，针叶林苔藓层的个体密度和类群数显著高于枯枝落叶层（P<0.01）。三种植被的密度-类群指数也存在显著差异（P<0.01）。土壤大型动物的生物量在6月最高。杰卡德指数表明，受干扰草甸与其他植被的土壤动物群落相似性最低。研究表明，植被类型对土壤动物群落结构有显著影响，坡向、海拔和干扰也有一定影响。
