摘　　要：To discuss the character of soil animal community and its diversity in mulberry tree orchard,from February to September,1999,we investigated the soil animal community and its environment in mulberry tree orchard in Laibang town,Yuexi county.Faunas collected were 3804 individuals which belong to 5 phyla,12 classes and 34 genera. Among them 4 genera were dominate and 7 genera were common.These constitute 94.45% of the total collected population. The result shows:the more species and individual numbers and the higher evenness,the higher the soil animal community diversity.Moreover,the longer the mulberry tree planted,the higher the index of H,E,N and DIC for soil animal community. In the sample with more destructive insects,S,E and H values for soil animal community are high. The genera and individual numbers of soil animals decrease with the increase of soil depth,but casually increase a little bit in some sample field. The individual numbers are the highest in spring,then in autumn,and then in summer,and the least in winter on the whole.Approximately,the diversity index of soil animal community in the mulberry tree orchard is higher than that in the tea garden.To discuss the character of soil animal community and its diversity in mulberry tree orchard,from February to September,1999,we investigated the soil animal community and its environment in mulberry tree orchard in Laibang town,Yuexi county.Faunas collected were 3804 individuals which belong to 5 phyla,12 classes and 34 genera.
