英文摘要: The effects of the characteristics of the river basin on species numbers of fish had been studied by using regression analysis and principal components analysis (PCA). The number of endemic fishes related positively with the number of all species (p < 0.01). The diversity of all species related positively with basin area (p < 0.01), length of mainstream (p < 0.05), and the average river discharge (p < 0.01) respectively; related negatively with the falling gradient (p < 0.05). The diversity of all species per unit area or per unit length related negatively with length of mainstream or basin area (p <0.01), average river discharge (p < 0.05) respectively; related positively with the falling gradient (p < 0.01), the runfall of the rivers (p < 0.01) respectively. There were positive significant correlationships among the diversity of endemic fishes and the basin area (p < 0.05), length of mainstream (p < 0.05), and average river discharge (p < 0.01) respectively. The diversity of endemic species per unit area related negatively with length of mainstream (p < 0.01), average river discharge (p < 0.05) respectively; related positively with the falling gradient (p < 0.01), the runfall of the rivers (p <0.01) respectively. The diversity of endemic species per unit length related negatively with basin area (p < 0.05); related positively with the falling gradient (p < 0.01), the runfall of the rivers (p < 0.01) respectively. The result of PCA showed that the 1st and 2nd principal components revealed correlations among relative and absolute numbers of fish species and the characteristics of the river basin respectively.
