Abstract: An investigation was conducted on the arthropod community in Castanea henryi forest under five different management modes, to study the effects of the management modes on the structure and diversity of arthropod community. Under the five different management modes, the structure and diversity of arthropod community had greater difference. In the C. henryi forest with careful management and no application of chemicals, arthropod community had the highest species diversity and stability, the diversity index of phytophagous groups was the highest, and the relative abundance of natural enemy groups was also the highest, which had high effectiveness in controlling pests and was disadvantageous to the outbreak of dominant pests. In contrast to the managementabandoned mode, careful management would improve the species diversity of canopy groups, but the use of chemical pesticides would decrease the species diversity and evenness of each functional group, and increase the relative abundance of phytophagous groups.
