摘要

Select three typical water areas as research objects, include: Yuqiao reservoir as typical water area of the drinking water source area; the main stream of Haihe river (downtown area)as typical water area of the major fiver and urban landscape water area; Dagu estuary as the typical water area of offshore sea area. The species and density and biomass and biodiversity of phytoplankton and zooplankton and benthon were used to be aquatic ecology index, try to build the index system of three typical water, evaluate the current situation of water pollution, provide a scientific basis of protecting and rehabilitating the aquatic ecology.
