The field experiment about research had been carried out in Dong Fanghong Farm, Changsha, Hunan Province from May to November in 1999. A through investigation and study was made on species component, structure, and the dynamic characteristics of rice field spider community. The result of the research on community structure makes it clear that there are total 43 species 29 Genus 11 families of spider in the rice field. The dominant families are Lycosidae, Lingphiidae, Theridiidae and Terahnathidae and the dominant species are Pirata subpiraticus, Vmmeliata, insecticeps, Coleosoma simon and Tetragnatha maxillas. In the early rice field of the different types of fields, the dominant species of spiders haven't been altere, which are mainly Pirata subpiraticus and Vmmeliata insecticeps. In the late rice field, there exists replacement in the dominant species of spiders. A preliminary explaination was made for the alterative phenomenon. The species of spider and number of individual had great difference in IPM and chemical control ricefield. Key word:Ricefield spider;Community;Dominant;Alteration
