摘要: Spatial longitudinal zonation in reservoir bays is poorly documented, and most published papers considered that longitudinal zonation in bays is similar to that in reservoirs. Our results from analyses of the benthic macroinvertebrate community in the bays of the Three-Gorges Reservoir, China, showed that a typical bay contains four distinct zones-one more zones than a reservoir. This newly distinguished zone lies along the mouth stretch of a reservoir bay, and we call it a mainstream zone because it is disturbed by the reservoir mainstream. The mainstream zone is characterized by a lower standing crop and a more unstable macroinvertebrate community than in the lacustrine zone. Longitudinal zonation of reservoir bays is related to their lengths, and lacustrine zones develop only where the bay is sufficiently long. Similar to reservoirs, longitudinal zonation in bays is also dynamic and is to some extent influenced by the ages of bays and seasons.
