| 摘 要： | 本文对东北高寒地区麦田中土壤动物进行了统计.共有13类,隶属3门、5纲,其中蜱螨类、弹尾类和线虫类占土壤动物总数的99.17％,为优势类群.土壤动物具有明显的季节变化,这与诸多环境因素的综合作用有关,即环境因素的变化可以使土壤动物的类群结构发生改变.麦田中0～15cm土壤动物的垂直分布无显著差异.

| Abstract: | The soil animal population in the northeast heavy frigid region can be divided into 13 orders, belon ging to 3 phyla,5 classes,of which Acarina, Collembola and Nematoda are dominant groups,being superior population. These three orders of soil animals are 99.17% of the total number. Other orders are rezedente groups. The soil anitnal shows obvious seasonal changes. There are evident differences in the varieties and quantities of soil animals with the seasonal changes of environmental factor.There's no significant difference in the vertical distributions of soil animals in the soil horizons of 0~15 cm in the wheat field. |
