The sewage port along the canal gradually shut down and reduce the source of pollution into the river. At the same time, since 2013, the actual situation of the river has been carried out from time to time.

Different types of green plants such as trees, irrigation, and grass on both sides of the river are exposed. A large amount of water planting plants, such as pupa, reeds, mugs, green onions, iris, etc., and promote the construction of "underwater forests" by developing proliferative release, scientific trimming water and grass, and continuously improve the water ecosystem. At the same time, the use of ecological means to pilot the hard -to -hard protection and gradually develop to the ecological slope protection; through ecological dispatching measures such as fine water, daily gates, and tidal flow flows to enhance the self -cleaning ability of the water body and "live" the water of the North canal Get up and realize "flowing water without rotting."

Today, the water quality of the North canal has reached the surface IV water standard throughout the year. Biological diversity has gradually recovered. There are 26 kinds of aquatic plants, more than 60 kinds of aquatic animals such as fish, shrimp and shellfish, and also attracted more than 200 kinds of birds.

Beijing Yang Hailong, head of the Engineering Management Section of the North Canal Management Office, introduced that since the construction of the urban sub -center, the Municipal Water Affairs Bureau has also proposed the construction of the "Tongzhou Weir" flood division project, such as the second phase of the Songzhuang flood area. After the "Tongzhou Weir" flood division system is completed, the flood control capacity of the North Canal can be increased from 50 years to 100 years.

Since the successful application of the Grand Canal in 2014, Beijing has been focusing on promoting the use of the Grand Canal Cultural Protection and inheritance. In October 2019, the newly -born Bei Canal realized the formal navigation from the 11.4 kilometers of river channels from Beiguanzha to the Gantang gate.
