英文摘要: Macroinvertebrates were quantitatively investigated in the Xiangxi River, the largest tributary in Hubei portion of the Three-Gorge Reservoir, from July 2005 to June 2006. The data and niche were analyzed, and the results showed that species richness was significantly different among seasons and tributaries of the Xiangxi River, and density was significantly different among seasons. Beatis sp., Epeorus sp., Serratella sp., Antocha sp. and Heptagenia sp. had large niche breadths, while Tetropina sp., Nemoura sp. and Simulium sp. had narrow niche breadths. The total niche overlaps of Beatis sp., Epeorus sp., Serratella sp. and Antocha sp. were high, but those of Simulium sp., Nemoura sp., Orthcladius sp. and Tetropina sp. were low. The niche overlap was significantly impacted by niche breadth and relative abundance. Distribution, niche overlap, the functional feeding groups and habit/behavior groups were the main way for them to allay their competition. Fig 2, Tab 5, Ref 25
