The monitoring of the ecological status of the Baiyangdian Basin in Hebei Province

It is learned from the Provincial Department of Ecology and Environment that Hebei recently launched water ecological monitoring work covering 38 counties (cities, districts) rivers, sedimentations, and reservoirs in 38 counties (cities, districts) in the Baiyangdian Basin to comprehensively find out the water ecological status of the Baiyangdian Basin, and actively promote the evaluation of the water body. Transition to a comprehensive element of water ecology.

The monitoring point of Baiyang Dian District is based on the monitoring of 33 points in the 33 points of Baiyangdian hydraulic biological monitoring and early warning construction project. The point reaches 41. There are 12 monitoring indicators, including aquatic organisms (floating plants, floating animals, large aquatic plants, large -scale benthic vertebrates, fish, foreign species), aquarium (shoreline natural index, hydraulic connectivity), water environment (water environment) Water quality, nutritional status), water resources (water level) and species diversity (bird diversity).

The monitoring point of the main river in the Baiyangdian Basin is based on the 40 points of the Baiyangdian hydrophobic biological monitoring and early warning construction project. It reached 83 and achieved full coverage of the main rivers of 38 counties (cities, districts).监测指标共有12项，包括水生物（大型水生植物、着生藻类、大型底栖无脊椎动物、鱼类、外来物种）、水生境（岸线自然指数、水力连通性）、水环境（水质、 The bottom mud pollution index, river sewage outlet, flood pollution index) and water resources (ecological flow).

The monitoring point of the main reservoir of the Baiyangdian Basin, select the representative Western Ocean Reservoir and the An Dazhuang Reservoir, set up 5 water ecological monitoring points in different areas such as the center of the reservoir, the exit port, the entrance, and the pollution area A total of 10 monitoring points. There are 8 monitoring indicators, including aquatic organisms (fish, water, large aquatic plants, foreign species), water and vascular (shore line natural index), water environment (water quality, nutritional status), and water resources (water body exchange rate).
