摘要
以两对不同使用方式的林地为研究对象，探讨耕作土地和自然林地的土壤动物与土壤营养成分间的关系，研究表明，自然林地的土壤动物种类、数量、生物量及自然林的土壤有机质、土壤微量元素的含量等均明显高于耕作土地，土壤动物的种类、数量、生物量与土壤营养元素的含量呈正相关；土壤动物体的矿质元素与其所在土壤的矿质元素相关显著。
Two pairs of differently used forest lands were used to study the relation between soil animals and soil nutrients of farming and natural forest lands. The results showed that the species, amounts, biomass of the soilanimals, organic matter contents and trace element contents of soil in the natural forestland were evidently more and higher than those in the farming forestland, the amounts of soil animals were positively relative to the nutritional conditions of soil; the mineral elements of soil animals were clearly relative to the mineral elements of soil and there were no clear correlativity of the trace elements between the animals and soils.
