"Let Chaohu Lake become the best business card of Hefei", "the best business card" has always been the key word of Hefei's ecological governance.
* The Economic Work Conference proposed to further promote the construction of ecological civilization and green and low-carbon development, and continue to fight the battle of blue sky, clear water and pure land.
In the past three years, Hefei has lived up to expectations, and in the first half of this year, the average water quality of Chaohu Lake reached Class III, the best level since monitoring records began in 1979. There is no peculiar smell of cyanobacteria along the lake, there are more and more rare migratory birds, and the effectiveness of Chaohu Lake governance is really "visible" and "smellable".
The lake is clear to smell.
Chaohu Lake is one of the five major freshwater lakes in China, it is like a pearl inlaid in the land of Jianghuai, and has the reputation of "800 miles of lake sky".
With the acceleration of urbanization and industrialization, the water quality of Chaohu Lake once became inferior Class V.
With the advancement of the comprehensive treatment of Chaohu Lake, Hefei has controlled pollution with an iron fist in the spirit of Baogong and worked hard for a long time in the spirit of Yugong to promote the systematic reshaping of the management system and the overall improvement of the governance level.
Under the background of rapid economic development and rapid population growth in the basin, the water quality of Chaohu Lake has gradually improved.
According to the latest data released by the Hefei Municipal Bureau of Ecology and Environment, from January to November 2023, the average water quality of the eastern half of Chaohu Lake, the western half of the lake, and the whole lake are all classified, and compared with the same period in 2022, the total phosphorus and total nitrogen, the main pollutants of Chaohu Lake, the eastern and western half of the lake, and the whole lake have decreased.
In the first half of this year, the average water quality in the lake area reached Class III, the best level since monitoring records began in 1979.
Great lake governance has always been a global problem, and Hefei has spent more than ten years of ecological practice to explore a set of large lake management solutions.
If you want to manage Chaohu Lake well, the key is to handle the relationship between the city and the lake. It can be clearly seen from the satellite cloud map that there are a total of 39 first-class tributaries in Hefei that flow into Chaohu Lake from all directions. Many of these tributaries flow through the urban area and discharge sewage into Chaohu Lake to varying degrees.
Chaohu Lake pollution, the problem is in the lake, but the root is on the shore, Chaohu Lake comprehensive treatment system implements the "five major projects" of clear water, Anlan, ecological restoration, green development, and enriching the people, and adheres to the "four sources of the same governance". This is the attitude of the Hefei Municipal Party Committee and the Municipal Government towards the governance of Chaohu Lake.
The hard work paid off, and after governance, Chaohu handed over a satisfactory "answer sheet".
The latest data shows that from January to November 2023, all 20 national examination sections in Hefei have reached the standard, with a compliance rate of 100%, and the compliance rate of the national control section has been stable and fully compliant since it reached 100% in 2020.
The water quality of the rivers entering the lake continued to improve, and the eight major rivers entering the lake all reached the level or above, except for the Nanqi River. In the first half of this year, the water quality of the Pai River reached the class level, and the Nanqi River also reached the class for three months.
At present, the water quality of Chaohu Lake is excellent, and an average of 4 billion cubic meters of water is delivered to the Yangtze River every year, making a positive contribution to the protection of the Yangtze River. For three consecutive years, cyanobacteria have no peculiar smell, and the date of the first obvious cyanobacterial bloom in 2023 is significantly delayed compared with 2022, and the cumulative cyanobacteria bloom area in Chaohu Lake has decreased by 86%。
A flock of birds that can be seen.
Birds are the vane of the ecological environment, and waterbirds are an important indicator of the health of wetland ecosystems. With the gradual improvement of the Great Lake, the abundant aquatic grasses and smart beauty of Chaohu Lake have attracted thousands of migratory birds to inhabit and winter.
The reporter learned from the Chaohu Lake Biological Resources Investigation Team that as of December 16, 2023, 287 species of birds have been recorded around Chaohu Lake, tying the bird record around Chaohu Lake in 2022.
The birds are coming, so that many "bird chasers" across the country come to visit, and the beauty of Chaohu Lake is spreading far and wide!
On December 16, a new bird species, the spotted Muscovy duck, was discovered in the 18 Lianwei wetland of Chaohu Lake, which was the first time that this bird species appeared in Chaohu Lake, and it was also "honored" to become the 287th bird species recorded around Chaohu Lake this year. One of the two people who found it was a birder from Shenzhen, whose name was Kent (natural name). Kent told reporters that he had heard that there were many precious birds in Chaohu Lake, so he traveled thousands of miles to see what was going on. On the weekend, he took a turn around the 18 Lianwei wetlands and recorded flocks of birds flying with his camera. "Thank you Hefei for preserving a valuable habitat for migratory birds. This is his emotion after bird watching in Chaohu Lake.
Preserving valuable habitat for migratory birds, which is extremely important for the conservation of biodiversity, can only be retained by providing a suitable environment for them to survive and protecting this large area of wetland, so as to retain birds and attract more rare migratory birds, from "rare visitors" to "regular visitors".
At present, there are 657 species of plants and more than 300 species of birds recorded around the lake. In the autumn and winter of last year, Hefei recorded the migration and transit of more than 2,000 Oriental white storks, the "treasure of the birds". In particular, on November 26, 2022, thousands of Oriental White Storks migrated through Chaohu Lake, which was spectacular. Last year, more than 9,000 red-headed gulls were recorded in Hefei, becoming a well-deserved "champion bird" among the migratory birds of Chaohu Lake, and there are more and more rare "national treasures" such as yellow-breasted buntings and white cranes.
A beautiful picture of unfolding.
Today's Chaohu Lake is full of ecological pictures of "clear water, green shore and beautiful scenery": the ecological wetland is verdant, and flocks of birds sometimes frolic on the water, sometimes stop on the shore to forage for ......
At the end of July 2022, the top ten wetlands around Chaohu Lake were fully completed. Looking down from the air, the ten wetlands around Chaohu Lake are like pieces of jade "beads into a chain", building a water ecological and water security barrier around Chaohu Lake, and it is also in this year that Hefei was rated as an "international wetland city".
It is worth mentioning that in the year, the performance evaluation of the "Shanshui Project" in the Chaohu Lake Basin ranked first in the notice of the Ministry of Natural Resources for two consecutive years, which indicates that the biodiversity of Chaohu Lake is gradually recovering, and the ecological "appearance" of Chaohu Lake is getting higher and higher.
What is surprising is that in terms of economic development, Hefei's GDP has crossed 800 billion steps, breaking 1 trillion yuan, and in terms of ecological environment, Chaohu Lake pollution has not increased but decreased. Hefei has proved that economic development and environmental protection can be developed at the same time, symbiosis and common prosperity.
The symbiosis of the city and the lake, the harmony of man and water, can never be achieved overnight, nor once and for all, and Hefei is using "firmness" and "sincerity" to continue to write a new chapter of innovation and long-term success, and the "best business card" is being presented wonderfully.
