摘　　要：对色季拉山高山松林、箭竹-桦木混交次生林、高山栎-高山松混交次生林、川滇高山栎林、灌木冷杉林、杜鹃林、冷杉林、高山柳-冷杉林、方枝柏疏林和高山草甸9种植被类型中土壤动物多样性进行调查。结果表明,在高山柳、冷杉林、杜鹃林、冷杉林、高山栎纯林生境中土壤动物的多样性都较高;土壤动物的多样性与丰富度、均匀度呈正相关,与优势度呈负相关,与个体数没有直接相关关系。Soil animal diversity of nine vegetation types in Sejila Mountain was surveyed,including alpine pine forest,Birch-Arrow bamboo mixed forest,alpine pine-alpine oak mixed forest,alpine oak shrub,fir forest,Rhododendron-Fir forest,Cupular willow-fir forest,Sabina saltuaria open forest,Alpine meadow.The results showed that the animal diversity level of alpine pine forest,Birch-Arrow bamboo mixed forest,alpine pine-alpine oak mixed forest was higher.There were positive correlations between soil animal diversity and richness,evenness,negative correlations between soil animal diversity and dominance,no direct correlations between soil animal diversity and individual number.
