Evaluation of ecological status and protection countermeasures of Baiyangdian wetland

Based on the field data, the ecological status of Baiyangdian wetland in the aspects of quality and quantity of water, phytoplankton, hydrophyte, zooplankton, fish and birds was evaluated to provide the basis for repair and utilization of Baiyangdian wetland ecosystem. The results showed that water quantity of Baiyangdian is an important factor affecting its water quality and species. Compared with historical data, the water quantity of Baiyangdian wetland is proved to reduce with serious water pollution, and decline in biodiversity. Because of the ecological water diversion in recent years, Baiyangdian ecosystem has been restored to some degree. Some countermeasures were put forward to protect the ecological environment of Baiyangdian wetland, establish a stable mechanism of ecological hydrating, intensify efforts to governance of pollution sources, and build up restoration project of its wetland ecosystem.
