Three-Gorge Project (TGP), the largest water conservancy
project ever built, has greatly changed the
original Yangtze River ecosystem (Wu et al., 2003), and
the impacts of TGD on the environment and water
ecosystem have become focuses of world attention. In
the present study, we have investigated the dynamics of
phytoplankton community structure and abundance in TGR and its anabranch, the Xiangxi River. Since
erection of the TGR, algal blooms have been detected
in the Xiangxi River and the influx region in the rainy
and dry seasons.
