| 摘 要： | 对黑龙江省西部沙地进行的土壤动物调查，选取了5个不同植被群落样地，共获得土壤动物40类，2240只。隶属于4门，6纲，11目，其中类群数最多的为昆虫纲，个体密度最大的为线虫类。对群落特征指数分析结果显示，DG指数是能够从总体上反映个体数和类群数变化的群落特征指数。从土壤动物垂直分布来看，各群落土壤动物在垂直方向上的变化都很明显，土壤动物的种类和数量基本上是随着土层的加深而递减。 |

| Abstract: | By investigating into the soil fauna in the west sandy land region of Heilongjiang Province, we have obtained 2240 soil faunas which could be divided into 40 kinds, belonging to 4 phylums,6 classes and 11 orders in 5 different communities. Among them, the species number of insect class is the most and the individual number of Nematodes is the largest. The analysis of community characteristic indexes displays that the DG index can reflect the changes of species and quantity. The study of vertical distribution of soil faunas showed that it has clear changes in different layers and the species and quantity of soil faunas are decreased with the drop of soil layer. |
