The Effect of Hydrological Regime on Phytoplankton Community

Phytoplankton is an important one of primary production and the indicator of the environment in the ecosystem of reservoir.The effect of hydrological regime on phytoplankton community was regarded as necessary for management of water quality.This study is, at present, mainly the effect of water retention, water level on the species component, standing crop, spatial pattern (including vertical and horizontal distribution) and succession of phytoplankton community.
