Structure and Seasonal Dynamics of Arthropod Community in Peach Garden

Structure and dynamics of arthropod community in peach garden were studied through the function group and nutrition class. Dominance, diversity and evenness indexes of arthropod community were analyzed. It was indicated that function group could be used to analyze community structure because several similar species were amalgamated into function group reasonably, and it was more convenient than species in the study. Compared with the peach garden controlled chemically, the stability of the arthropod community in the ecological peach garden was higher because diversity and evenness indexes of arthropod community in the ecological peach garden were both higher than those in the peach garden controlled chemically.
