T o discuss the cha acte of soil animal community and its dive sity in mulbe y t ee o cha d, f om Feb ua y to Septembe , 1999, we investigated the soil animal community and its envi onment in mulbe y t ee o cha d in L aibang tow n, Yuex i coun ty . Faunas collected w e e 3804 individuals w hich belong to 5 phyla, 12 classes and 34 gene a. A mong them 4 gene a we e dominate and 7 gene a we e common. T hese constitute 94. 45% of the total collected population. T he esult show s: the mo e species and indiv idual numbe s and the highe evenness, the highe t he soil animal community dive sity. M o eove , the long e t he mulbe y t ee planted, the hig he the index of H, E, N and DIC fo soil animal community. In the sample w ith mo e dest uctive insects, S, E and H values fo so il animal community a e hig h. T he gene a and individual numbe s of soil animals dec ease w ith the inc ease of soil depth, but casually inc ease a little bit in some sample field. T he individual num be s a e the highest in sp ing , then in autumn, and then in summe , and the least in winte on the whole. App ox imately, the dive sity index of soil animal community in the mulbe y t ee o cha d is hig he than that in th
