%X The study on the community structure of arthropod in the alpine cabbage fields of Hubei Province showed that the dominant pests were Brevicoryne brassicae,Mamestra brassicae and Plutella xylostella,while the dominant natural enemies were Diaeretiella rapae,Cotesia plutella,Erigonidum gramiaicolum and Syrphus corollae.The richness,diversity index,evenness index and dominance index of pest and natural enemy sub-communities all changed with time.The dominance index of pest sub-community was higher,while its diversity and evenness indices were lower than those of natural enemy sub-community.Based on fuzzy clustering analysis,the pest and natural enemy sub-communities of 14 time sequences were grouped into 4 and 3 sorts,respectively.
