Abstract: Community structure of carabids and spiders in agricultural landscape was investigated by pitfall traps in suburb of Qianjiang city, Hubei Province from June to October, 1995. The results indicate that 5 landscape elements have significant role in preservation of carabids and spiders.（1） In margins of rice fields, diversity index and species of carabids and spiders were the highest. 2)In crop-forest interval fields, evenness of carabids and spiders was the highest, diversity index was second. 3) flood fields in which no insecticide was applied had high number of carabids and spiders.The dominant species are Pheropsophus javanus , P . Jessoensis and Padosa astrigera respectively.（4) Dry farmlands in which minor insecticides were applied had high number of carabids. The maincarabids is Leistus magnus. 5) Home gardens existed large number of spider. The dominant spiders is Padosa laura. Correspondence analysis shows correspondent relationships between landscape elements and dominant species of carabids and spider, between conventional farm lands and the 5 landscape elements mentioned above. The results provide reference for design and management of agriculture landscape.
