Coordinated Development of Water Environment Protection and Water Ecological Carbon Sink in Baiyangdian Lake

“The Hebei Xiongan New Area Planning Outline” states that the carbon sink of the water body should be improved and the quality of Baiyangdian water should be improved by cleaning the sludge, but the treatment of endogenous pollution in the water body will release a large amount of carbon dioxide, wh...
