摘要: 对小兴安岭森林生态系统6个主要林型的凋落叶、土壤动物和土壤三者之间营养元素关系研究,凋落叶、土壤动物和土壤中营养元素的平均含量不同,它们的变异程度也不同。蚯蚓、线蚓、蜈蚣和其它类群土壤动物体内营养元素的方差分析结果表明,K、Ca、Mg、Fe对土壤动物的生长发育影响较大。凋落叶、土壤动物和土壤之间K、Na、Fe的线性关系较强,反映了凋落叶-土壤动物-土壤间K、Na、Fe联系密切。凋落叶和土壤中营养元素与土壤动物的生物量、密度和类群数的关系密切,平均关联度的顺序为,类群数>生物量>密度。

Abstract: This paper studied the relationships of nutrient elements of litter,soil fauna and soil from six major forest types of Xiao Hinggan Mountains.It was revealed that both the average content of elements and the variance from litter,soil fauna and soil in different forest types were not the same.The variance analyses(ANOVA) of nutrient elements from earthworm,enchytraeidae,centipede and other soil fauna showed that K,Ca,Mg and Fe had an influence on the growth of soil faunas.The significant linear relationship of K,Na and Fe with litter,soil fauna and soil indicated that these elements were closely related with litter,soil fauna and soil.Furthermore,the nutrient elements in leaf litter and soil were closely related to the biomass,density,and group of soil fauna.The order of the average relevant coefficient was: group>biomass>density.
