摘 要(英文)：So il fauna communit ies w ere studied in various 20 year-old regenerated vegetat ion types at the Heshan Research
Station. There was no significant difference in fauna individual number betw een the mixed A cacia fo rest and A cacia mangium
forest. How ever, there was significant difference in fauna individual number betw een these two fo rests and the grassland, p ine
and m ixed S ch im a sup erba fo rest (p < 0105). The low est fauna individual number w as found in grassland w h ile m ixed A cacia
fo rest had the h ighest group abundance (p < 0105). The variat ion in group abundance at various vegetat ion types o r betw een
w et and dry seasons w as small compared to the changes in fauna individual number. Based on DG index these man2made
vegetat ion typesw ere classified into th ree catego ries: m ixed A cacia fo rest (… ) , A cacia m ang ium fo rest ( ) , grassland (À ) ,
p ine (À ) andm ixed S ch im a sup erba fo rest (À ). Bo th the fauna individual number and group abundancew ere dist inct ively low
during the w et season as compared to dry season. Soilfauna in F1 so il layer w as significant lyricher than in F2 and F3 layers
(p < 0101). Entomobryidae, Cyphoderidae, Formicidae, Campodeidae, Thom isidae, Heteropodidae, Leptonet idae, Coleoptera larvae, Himiptera larvae and Homop tera larvae w ere significant ly co rrelated with changes of the w ho le so il fauna communities
(p < 0105). Our results show ed that DG index truly reflects soil fauna community characterist ics in various art ificial vegetation types.
