Dynamic Monitoring of Soil Animals in Different Functional Zones of Baoshan Iron and Steel Plant

对上海宝钢厂区不同季节、不同区域土层中土壤动物群落组成、垂直分布、季节变化和多样性进行了调查分析，结果表明：春季土壤动物类群和数量相对较少；办公区的土壤动物相对较少；垂直分布特点为0～5cm〉5～10cm〉10～15cm；螨类和弹尾目是优势类群，螨类所占的比例严重影响着群落的多样性。

Soil animals are some of the most important part of terrestrial ecosystem, and they are also the very important consumers and special decomposer in the ecosystem. They have the function that cannot be substituted in the ecosystem. This paper analyzes the composition of the community, vertical distribution, seasonal variation and diversity of the soil animals in different seasons, different areas and different layers in Shanghai Baoshan Iron and Steel Plant. The results indicate： the groups and number of soil animal are relatively small in spring, and they are also relatively small in the office zone; the characteristic of vertical distribution is 0--5 cm soil layer 〉5--10 cm soil layer 〉 10--15 cm soil layer; Arcarina and Collembola are the dominant groups; Arcarina have an obvious effect on the diversity of soil animals.
