Diversity of Aboveground Invertebrates in Dinghushan and Its Correlation with Litter

The diversity of aboveground invertebrate communities and its correction with litter were studied using pitfall traps in three representative forests in Dinghushan National Nature.7310 invertebrate samples were collected,which belonged to 3 phyla,7 classes,31 orders,and 58 families (superfamilies).Formicidae was dominant,and Araneae,Oribatida,Entomobrydae,Biphyllidae,Gryllidae and Prosophilidae were common.The aboveground invertebrate in monsoon evergreen broad-leaf forest had the highest values of diversity (H) and evenness (E),which were similar to the values in broad-leaf and pine mixed forest and there were the lowest values in pine forest,but the value of dominance was the highest in pine forest.There was not significant similarity among the three aboveground invertebrate communities.The annual litter production was significant positive correlation with the diversity and evenness of aboveground invertebrates and significant negative correlation with the dominance.There were significant negaive correlation between return period of litter and the diversity and evenness of aboveground invertebrates.Significant positive correlation showed between return period of litter and the dominance.
