What is the water quality environment of underwater forest in East Lake, Wuhan?

Recently, news about the underwater forest of East Lake in Wuhan has been frequently exposed, and many friends have started a new journey, hoping to be satisfied here. You can feel the unique humanistic charm and feelings, and the water quality and ecological environment of East Lake also affect the heartstrings of millions of people.

: The sun shines through the bottom of the lake. Under the blue waves, the water plants are swaying in it. Fish walk through the "underwater forest" and waterfowl play in the distance. Recently, the newly-grown "underwater forest" in Egou Bay, Zhengguo Lake, East Lake, Wuhan has attracted many citizens to stop and watch.

"The cattail leaf fan is in the shape of Ceratophyllum, and its feathers are called Myriophyllum. This strip-shaped plant is called Vallisneria angustifolia, which is the favorite plant of grass carp. " The staff introduced that this "underwater forest" is the result of their experiments for more than four months.

Since April this year, the water ecological restoration project of East Lake has been officially implemented. The aquatic ecosystem with submerged plants as the core was rebuilt and the aquatic ecology of East Lake was restored through measures such as cleaning up water garbage, setting up isolation fences, planting submerged plants and releasing aquatic animals.

Looking at the lake now, a pool of clear water is exceptionally clear, the water plants are swaying, and the fish and shrimp walk through it, setting each other off.

Underwater forest of East Lake in Wuhan

Since the 1960s, the water ecosystem of East Lake has been seriously degraded due to the rapid expansion of the city and the interference of human activities. The coverage of aquatic plants in the lake decreased from 70% to 3.3%, and the diversity of benthos and fish continued to decline. People can even smell an unpleasant smell when they walk by the lake.

In recent years, Wuhan has taken a series of measures to continuously improve the water quality of East Lake, such as rain and sewage diversion, returning fishing to the lake, checking and rectifying sewage outlets, and ecological restoration. In March 2000, the water quality of Zhengguo Lake was monitored for the first time in 40 years. At present, 80% of the water in the whole East Lake is kept in the first-class water quality.

In the process of aquatic ecological restoration, the growth of submerged plants and the purification of lake water complement each other. Li Yu, head of Wuhan Bishui Group Water Investment Company, told the reporter that in three months, the team planted five kinds of submerged plants in four areas according to different proportions, and planted nearly 460,000 clumps, comparing the ecological restoration effects of different methods.

"The restoration of aquatic ecology requires long-term efforts, and the restoration of large-scale aquatic plants in open waters. There is still a lack of successful experience and implementation cases in China for reference. " Li Yu said that in order to find out the influencing factors of aquatic ecological restoration, the project has established the technical route of "demonstration area, one area and the whole lake" and adopted different planting methods to restore submerged plant communities.

In August, the mid-term evaluation report of the project showed that the water ecosystem in the demonstration area was stable, and the transparency and water quality were significantly improved compared with those outside the fence. After experiencing the test of the surge of water level in rainy season and the pollution of urban rainwater entering the lake, the growth of "underwater forest" exceeded expectations.

"Lake management is not an easy task, and lake management in cities is even more difficult." Li Donghui, secretary of the Working Committee of Wuhan East Lake Scenic Area, said that it was not a day's work to harness the water of East Lake, and it needed continuous investment and long-term efforts.

"At present, while observing and evaluating, we are preparing to expand the planting area." Li Yu said that if the experiment is successful, in 2022, "underwater forest" will account for one-tenth of the waters of East Lake. "The ideal state is to let submerged plants grow naturally to one-third of the lake area, and then the East Lake will return to its previous appearance."

Water quality of East Lake in Wuhan

Wuhan Environmental Protection Department: The water quality of East Lake was maintained at swimming level in the first half of the year.

What's the secret behind keeping the water quality of East Lake at the swimming level of surface water? What's the secret behind it?

Some netizens worry that the East Lake Greenway has become a punching point for Wuhan tourism.

In recent years, on the basis of the water quality control of East Lake in provinces and cities over the years, East Lake Scenic Area has comprehensively implemented the long-term system of rivers and lakes, comprehensively carried out sewage interception and dredging, water ecological balance and water purification, paid attention to promoting water quality self-repair and enhancing the "immunity" of East Lake water body, instead of adopting "dialysis" treatment of artificial intervention to change water.

Specific measures are as follows:

First, by building the East Lake Greenway, locking the coastline, ending "occupying the lake" and reducing non-point source pollution; Second, returning fishing to the lake, completely prohibiting commercial farming, and realizing self-purification, restoration and balance of water bodies; Third, through the transformation of small cruise ships, eliminate fuel cruise ships and implement "comprehensive clean energy utilization of ships" in East Lake waters; Fourth, through the East Lake water environment improvement project and lake pond improvement, scientific management, and solidly promote water ecological restoration; Fifth, through the investigation and rectification of sewage outlets, establish a list of sewage outlets in lakes and promote the comprehensive interception of pollution in East Lake; Sixth, with the help of "folk lake chiefs" and social forces, with the participation and supervision of social lake protection volunteers, the public is actively involved in the daily maintenance and management of lakes through regular inspections by water, land and air; The seventh is to encrypt the water quality monitoring points, accurately analyze the water quality, and publicize the water quality of East Lake as required.
