| 摘 要： | 研究表明，芜湖市郊农田土壤动物群落的组成与数量随污染程度的加重而减少，土壤动物密度也呈同样的变化趋势，特别是中小型土壤动物，优势类群数量发生较大消长，常见类群和稀有类群的组成逐渐减少．多样性指数H与重金属污染程度之间关系因受到季节的影响而变得复杂：冬季和初夏污染较重样地优势类群数量减少，群落均匀性指数E增加而优势度指数C减小，多样性指数H较高；而春季处于过渡阶段，某些类群(如螨类)数量爆发，C增高，H较小．土壤动物群落密度一类群指数DG随污染加重而减小．受到重金属污染的农田土壤动物的表聚性减弱，甚至出现逆分布现象．图1表4参15 |

| Abstract: | The effect of soil pollution on the structure of soil animal communities in the suburb of Wuhu, Anhui was studied. The results showed that compared with soil animal communities of the farmland with low heavy metal pollution, those of the heavily polluted farmland were found with fewer groups and smaller amounts of soil animals; the individual numbers of dominant species were changed, and the common and rare species reduced or disappeared; community diversity index H increased in winter and early summer, but decreased in spring; DG index decreased in heavily polluted farmland; and the surface aggregations of soil animals were not obvious. In addition, the abundance of soil animals was not related positively to the amount of organic matters. Fig 1, Tab 4, Ref 15 |
