【摘要】 对小兴安岭南坡的土壤动物进行了生态序列研究。按等高差系列共选８ 个样地，分属不同植被类型。对各样地土壤动物调查分析结果表明：在生态序列诸环境因子中，海拔高度是主导因子；土壤动物类群和个体数量大致随海拔高度的增加而增加，这与一般情况相反，乃因取样区特殊的小气候所致；云冷杉林土壤动物类群和个体数量都比其它群落少。更多还原

【Abstract】 The ecological series of soil animals in southern Xiao Hinggan Mountains was studied Xiao Hinggan Mountains. Eight sample plots were selected according to a series of equal altitude difference, which belonged to different vegetation types. By investigating and analysing soil animals of every sample plot, It can be seen that the altitude was the key one among the factors of ecological series. Both the groups and indviduals of soil animals almost increased with increasing altitude, which opposited to ordinary cases, resulting from special micro climate of the studied area. Both the groups and individuals of soil animals of Picea and Abies forest were lesser than other communities.更多还原
