Abstract: From May,1986,to December,1992,We investigated Soil animals in 4 habitat types in the Jiuhua Mountain for seven times.16608 soil animals have been collected They belong to 5 phyla 13 classes 37 orders and 95 Families.Among them,Acarid,Collembola and Nematoda are dominant genera which account for 74.41%of the total collected population,The rules of vertical change in soil animal community are:Except Community Ⅰ which is mostly affected by human activities the group number increases with the increase of sea-level elevation and organic matter the individual number (N)and density(D)of middle and small soil animals decrease with the increase of sea-level elevation and the decrease of temperature;Shannon's indices(H)of communities are Ⅳ>Ⅲ>Ⅱ>Ⅰ,which are in accordance with the change of group number.The trend of the changes in S.D of each community and H.E of large soil animals is November>December>May>August.The indices of H and E of middle and small soil animals are contrary to those of large soil animals,which are May>August>December>November.The habitat condition is superior.community Ⅳ which hasthe most organic matter has the most narrow distribution pattern.Community Ⅰ which is mostly affected by human activities has no narrow distribution pattern community.

Key words: Jiuhua Mountain, Community of Soil animal, Habitat distribution type
