Abstract: The paper analyzed the community and biodiversity of soil animal in heavy metal polluted soil in Huainan city.The results showed that the species and number of soil animals decreased with the increase of pollution degree,sodid their density.The dominant and common species decreased obviously in seriously polluted soil.Some important indexes of community structure such as diversity(H),eveness(E),density group(DG) tended to decrease with the pollution increase,while dominance index(C) increased and then decreased outside the coal ash site.H index was positively correlated with E index,but it was negatively related with C index.There was no close correlation between soil animal number and the content of organic matter in soil.
