Abstract: A field survey with random block design was conducted to study the effects of different landscape patch structure on the arthropod community in tea plantations. In the tea plantations with small woodland (QM) or Acacia confuse (XS) patches, predatory spider had the highest proportion, occupying  62.3% and 69.5% of the total arthropods, respectively, being significantly higher than that in the tea plantations close to paddy field (DT) or near a village (RJ). The tea plantations with QM had the highest diversity index and species richness of arthropod community, while the evenness index and dominance index were not significantly different from the other tea plantations. The tea plantations with QM and XS had much richer natural enemies, and the order of the diversity index, evenness index, and richness index of natural enemies in the tea plantations ranked as QM>XS>DT>RJ. It was suggested that landscape patch structure had great effect on the diversity of arthropod community in tea plantations.
