摘  要：
为了了解大兴安岭不同冻土带湿地土壤动物的群落特征,在每个冻土带分别选取沼泽和草甸样地,进行调查分析。水平分布调查表明,土壤动物的个体数量和类群数量分布一致。垂直分布调查表明,无论是个体数量还是类群数量,中小型土壤动物的表聚性明显,大型土壤动物的表聚性不明显。多样性分析表明,大型土壤动物多样性的水平分布呈"V"字形,中小型土壤动物的多样性指数呈均匀分布。一元线性回归分析表明,大型土壤动物的个体数量和类群数量与凋落物的现存量呈显著正相关,说明凋落物现存量对大型土壤动物的分布影响较大;中小型土壤动物的个体数量和类群数量与有机质、全氮和地温相关性显著,说明这3种土壤因子对中小型土壤动物的分布影响较大。

摘  要：
We investigated wetland soil fauna in swamps and willow-shrub meadows of the different types of tundra to study the characteristics of wetland soil faunal community in Daxing'an Mountain. The investigation of the horizontal distribution shows that the number of individuals of wetland soil fauna is consistent with the number of species of wetland soil fauna.The investigation of the vertical distribution shows that the individuals and species of soil meso-micro fauna gather obviously in the surface layer of soil,but those of soil macrofauna do not gather obviously in the surface layer of soil. The analysis of the diversity shows that the horizontal distribution of soil macrofauna diversity is"V"shaped,and the soil meso-micro faunal diversity index shows a uniform distribution. By linear regression analysis,the individuals and groups of soil macrofauna are significantly positively related with litter,suggesting litter closely relates with the distribution of soil macrofauna.However,the soil meso-micro fauna are significantly positively related to soil organic matter,total nitrogen and soil temperature,indicating that these soil factors closely related with the distribution of soil meso-micro fauna.
