%X This paper deals with species-abundance distributions and diversity in two regions, one cover-crops-growing region and one herbicide-treated region.There are significant differences in species-abundance distributions between cover-crops and citrus subcommunity.Significant difference in species richness, divesity and existed between two eegions both for cover-crops and citrus. The diversity of arthropod community is the lowest in winter, the highest in summer, and it increases in spring, decreases in fall. The dynamics of evenness . show the same pattern as diversity does. And the influence of dominant species to diversity and evenness is important. This paper also provides a revised index of niches, and four kinds of indexes of niches overlapping are discussed.
