A field investigation was made from July 2007 to May 2008 to study the distribution dynamics of macroinvertbrates in several streams that flow to the Danjiangkou Reservoir. The results showed that Baetis spp., Heptagenia spp., Caenis spp., Ceratopsyche spp, Parakiefferiella spp. and Eukiefferiella spp. were dominant groups in the study period, and their relative abundances were 20.4%, 11.5%, 9.1%, 5.9%, 11.6% and 5.0%, respectively. The difference in macroinvertbrates density was significant, but the differences in macroinvertbrate biomass, Shannon-Wiener index and Margalef index were not significant. Canonical correspondence analysis showed that the influence on the macroinvertbrates varied in different seasons. Fig 4, Tab 3, Ref 23
