摘要
对东北羊草草原不同生境土壤动物群落多样性研究表明 ,生境条件愈优越 ,土壤动物的多样性指数愈高 ,种类则愈丰富 .土壤动物群落的多样性与土壤有机质和全N含量呈正相关 ,与 pH呈负相关 ,与土壤自然含水量和全P含量关系不明显 .土壤动物群落多样性随土层深度的增加而减少 ,且表聚性明显 .
Studies on the diversity of soil animal community in different habitats of Leymus chinensis grassland show that the better the habitat condition, the higher the diversity index of soil animals and the richer the species. The diversity of soil animal community was positively related with the contents of soil organic matter and total N, and negatively related with soil pH value, but not significantly related with the contents of soil water and total P. It was decreased with increasing soil depth, and had an obvious surface aggregation.
