摘 要(英文)：With litterbag method ,this paper studied the leaf litter decomposition of monsoon evergreen broadleaf forests in Dinghu Mountain ,and the dynamics and diversity of soil fauna community within and out of bags from Dec. 2001 to Dec. 2002. The results showed that the decomposition rate of leaf litter in bags with different mesh sizes was decreased in order of coarse size > medium size > fine size. Mixed litters decomposed more rapidly than single species litters. Acarina was the most abundant group of soil fauna in litter bags and soil during the process of litter decomposition ,while the individuals of Collembola had a greater change during litter decomposition. The density , diversity index ,and the numbers of groups and individuals of soil fauna in litterbags increased with litter decomposition ,especially in the 9th month. The diversity index and the numbers of the individuals of important soil fauna in soil were higher in early than in mid-and late stages of decomposition. The decomposition process of leaf litter and the dynamics of soil fauna community diversity were correlated with litter quality ,temperature and rainfall in the site.
