摘　　要：系统调查了高黎贡山国家自然保护区土壤性质与土壤动物的种类与分布。海拔高度决定土壤的性质,土壤温度、湿度、有机质含量和磷的含量与海拔有明显的相关。在不同海拔11个样地共采集到大型土壤动物标本1万余号,分属于2个门,5纲,18目,47科,13亚科。等翅目Isoptera、膜翅目Hymenoptera和弹尾目Collembola昆虫是主要类群,随着海拔高度的增加,土壤动物数量和种类,以及Simpson指数、Shannon-Wiener指数和均匀度指数都是先增加然后减少。在海拔1500～2500m左右数量最多,然后递减,土壤动物的分布以中山部最多而山顶部和底部较少的变化趋势。土壤动物的分布受海拔和土壤性质的影响。The Gaoligong Mountain, as the subtropics climate, is located in the collision region between the Indian tectonic plate and the Eurasian tectonic plate. In this experiment, the soil property, fauna community type and distribution of 11 samples in Gaoligong Mountain were studied from altitude 960 m to 3188 m. The results showed that the soil property was determined by altitudinal gradient. Significant correlation was observed in soil temperature, water content, organic contentand phosphorus content with altitudinal gradient （P 〈 0.05 ）. Two phylums （Annelida and Arthropoda）, three classes （Oligochaeta, Arachnida, Diplopoda, Chilopoda, Insect）, eighteen Orders, forty-seven Families and thirteen Subfamilys were included in the soil fauna. Isoptera, Hymenoptera and Collembola were dominant in these groups, and Coleoptera,Derampteraand and Diptera were common groups. A single-peak curve was appeared in the vertical distribution pattern of soil fauna. The number of the soil fauna individuals and groups, as well as the value of Simpson Index, Shannon-Wiener Index and Evenness Index gradually increased and then decreased with increase of elevation. The peak of soil fauna appeared in the areas from 1500 m to 2500 m above sea level. Soil fauna distribution and community composition were correlated with the soil property （ including in soil organic content, phosphorus content and water content） （ P 〈 0.05 ）. The results above indicated that the pattern of soil fauna distribution along the altitudinal gradient may be affected by the multi-factors, such as altitude, rainfall, climate, habitat, soil property and so on.
