【摘要】 在５种生境中共获土壤动物５１类，６１６１只，隶属４门８纲２１目３９科。其中大型土壤动物优势类群３类，常见类群７类。中小型土壤动物的优势类群为２类，常见类群为８类，构成了本区土壤动物的主要成分。大型土壤动物类群和个体数最多的是原始阔叶红松林。中小型土壤动物类群数最多的是人工红松林，个体数最多的是人工云冷杉林。大型和中小型土壤动物的类群数和个体数均随土层深度的增加而递减更多还原

【Abstract】 A total of 6161 soil animals in 51 groups, belonging to 4 phyla, 8 classes, 21 order and 39 families, were obtained from 5 habitats in Liangshui Nature Reserve. Concerning large-scale soil animals, there are 3 dominant groups and 7 frequent groups. To middle-small-scale soil animals, there are 2 dominant groups and 8 frequent groups. The virgin Pinus koraiensis broad-leaf forest has more groups and individual numbers of largescale soil animals. In man-made Pinus koraiensis forest, the group number of middlesmall-scale soil animals is the most. In man-made Picea and Abies forest, the individual number of middle-small-scale soil animals is the most. The groups and individual number of soil animals decreased with the increase of soil layer depth.更多还原
