摘要：We examined the relationship between fish species composition and environmental and biogeographical variables in 26 small and intermediate streams in the Guangxi Province. The variables estimated were stream width, stream order, vegetation cover, bottom substrate, altitude, longitude, and latitude. Altogether 4,433 specimens of 36 species were collected. Rhinogobius giurinus (Gobiidae) and Opsariichtys bidens (Cyprinidae) were the most common species, and they were found at 16 of the localities. Species richness was correlated with stream width. Canonical Correspondence Analysis showed that longitude was the only environmental variable that significantly explained community composition of the fishes. Intensive land use is suggested to be a cause off the lack of correlation with other environmental variables. Two fish species assemblages could be distinguished, one eastern and one western.
