摘要: 对不同林龄人工落叶松林的土壤动物生物量的研究表明,在不同林型中,大型土壤动物占总生物量的41.6~64.0%,中小型土壤动物为24.4~39.0%,湿生动物为8.9~25%.在土壤动物各类群中,蚯蚓生物量最大,线虫类次之,线蚓最小.土壤动物生物量与凋落物量、植被总盖度、土壤pH、土壤含水量和土壤有机质含量呈正相关关系.

Abstract: The study on soil animal biomass in larch plantation with different ages shows that in different stands, soil macroanimals occupy 41.6~64.0% of the total, middle-small size animals 24.4 ~ 39.0%, and hygrocolous animals 8.9~25%. Among them, earthworm is the maximum, nematode is the medium, and enchytraeidae is the minimum. Soil animal biomass is positively related to the litter, plant coverage, soil pH, soil moisture content and soil organic matter.
