| 摘 要： | 土壤动物作为生态系统的一个重要组成部分,其在土壤有机质分解、养分循环、改善土壤结构、影响土壤健康和植物演替中起着至关重要的作用。经调查,青海三江源的4种生态系统中,鞘翅目、弹尾目为主要的土壤动物类群。鞘翅目、弹尾目土壤动物群落结构具有明显的表聚性。4种生态系统中鞘翅目、弹尾目土壤动物多样性依次为:湿地生态系统高原森林生态系统高寒草甸生态系统高寒荒漠生态系统。三江源4种生态系统土壤动物群落的多样性相对偏低,鞘翅目、弹尾目土壤动物群落多样性指数与植被的丰富度呈正相关关系。土壤营养物质是影响鞘翅目、弹尾目土壤动物的主要生态因子。

| Abstract: | Soil animals are one of important parts in the ecological system. The results showed that Coleoptera and Collembola were the main soil animal flora in four ecosystem in Sanjiangyuan nature reservation region. Their diversity in descened orders were wetland ecosystem, forest ecosystem, alpine meadow ecosystem, and desert ecosystem. The number of individuals and species were both decreased gradually with the depth of soil increased. The community diversity of soil animals in Sanjiangyuan is lower than other places in China. The diversity index (H′) is closely correlated with the richness of the vegetation communities. The soil nutrition component is the most important ecological factor that effected soil animal community diversity in Sanjiangyuan nature reservation region. |
