Chaohu, connecting the Yangtze River, is about to communicate with the Huaihe River. As one of the five freshwater lakes, it is a pearl on the ecological territory in my country.

Hefei, a provincial capital city with a fast running, has a total economic volume of about three times, and the permanent population in the city is nearly 10 million. It is responsible for the new mission of comprehensive national science centers and the Yangtze River Delta urban agglomeration.

As a provincial capital city living around Dahu, Hefei used ten years of ecological practice to explore the large lake governance plan for the integrated protection and repair of landscapes, forests, lakes and sand.

Dahu Fu Green

At the end of July this year, with the completion of the third phase of the Eighteenth Lianxian Wetland, the total area of ​​100 square kilometers and the investment of nearly 6 billion yuan was fully completed. Overlooking from the air, the Chaohu Lake is inlaid in the land of Anhui, and the top ten wetlands around Chaohu Lake are like a piece of emerald "beaded chain", which builds the water ecology and water safety barrier around the lake.

The Chaohu Lake faces the Yangtze River in the east and Dabie Mountain in the west. Every year, 4 billion cubic meters of lakes enter the river. After the "leading Jiang Jihuai" project is completed, Chaohu will be connected to the Huaihe River.

Since the 18th National Congress of the Communist Party of China, Chaohu Governance has entered the fast lane and has launched a new chapter. Following the concept of landscape, forests, lakes and sand is the concept of the community of life, and based on systematic governance and ecological repair, Chaohu governance puts the relationship between people and nature in an important position.

Walking through the eighteen united wetlands, the grass is beautiful, and the river cricket is vertical and horizontal. Li Jiazheng, deputy general manager of Hefei Eighteen Lianyu Ecological Construction Management Co., Ltd., checks the growth of plant growth and water quality in wetlands every day. Originally, this is the fisherman of Feidong County, who has a history of more than 30 years, and Li Jiazheng is the head of the fishing farm. In 2017, in order to build and protect the wetland, all the 3,500 acres of water on the fishing ground were retired, and more than 200 farmers withdrew. At the same time, a total of 12,000 natural villages in the surrounding area retreated.

In the past ten years, the area of ​​the ten wetlands of the nest of Chaohu Lake has reached 15,000 mu, and 7005 households have been retreated. Some of them have become cyanobacteria fishing workers, some of them become wetland maintenancemen.

Hefei also provides the "red line" to protect Chaohu through legislation. Related local regulations clearly stipulate that natural recovery and manual repair are combined, and measures such as ecological hydration, vegetation recovery, and immigration relocation will enhance the ecological function of wetland.

Entering the Sanhe National Wetland Park of Feixi City, Hefei City, Bihe Yingri, a group of birds. The wetland park of more than 1800 hectares is located on the west bank of Chaohu, with a wetland coverage of 89.17%. 3,000 residents withdrawn and more than 2,000 acres of fisheries recovery, which is green here.

With wetland repair, biodiversity has also steadily recovered. Yu Lei, the person in charge of the diversity of the nest birds, told reporters that before 2006, there were only more than 170 bird species in the Chaohu Basin. Since 2021, Yu Lei ’s investigation team has found 258 birds, oriental white ravioli and yellow breasts. Wait for rare bird species to change from "rare customers" to "frequent customers."

City lake symbiosis

In July 2011, the State Council agreed that Anhui Province would revoke the prefecture -level Chaohu City and some administrative districts to adjust, and Chaohu has since become the Neihu of Hefei. Hefei has also become a provincial capital cities living in Da Lake, opening a new bureau of symbiotic development of a city and a lake.

Prior to this, Hefei's urbanization and industrialization were rapidly promoted. Chaohu had undergone "ecological trauma": urban sewage was remitted into Chaohu, and the water quality of the lake was a inferior V. Chaohu was also nicknamed the "foot basin" of the city by the citizens of Hefei.

"Chaohu pollution, the problem is in the lake, the root is on the shore, how to deal with the relationship between economic development and ecological environmental protection." Yu Zhongyong, director of the Chaohu Management Bureau of Anhui Province.

Through the establishment of a special basin management agency, the Chaohu Management Bureau of Anhui Province, the establishment of the Ncha Lake Ecological Protection and Governance Fund Pool, the construction of the Chaohu Governance Project Library, and the creation of the Chaohu Governance Think Tank, the "Kowloon Water Governance" of Chaohu Governance is "one dragon tube water". Go to the road of watershed governance and ecological repair.

The water system of the Chaohu Lake Basin is spread out, and 33 first -level tributaries are remitted into Chaohu. Data show that Chaohu pollution comes from urban life pollution. Governing the river first, rivers to treat pollution first. Hefei has invested about 15 billion yuan since 2012 to transform drainage pipe networks, build a new number of urban sewage treatment plants, and improve the standard of water outlets to purify the water source from the source. At present, Hefei has built 25 cities sewage treatment plants with a daily processing volume of 2.92 million tons.

The water purification workshop in Hefei Qingxi Water Purgatory is hidden in an open park in the western suburbs of Hefei. The whole place -designed sewage treatment plant treats the surrounding urban sewage daily, and the treated tail water flows into Chaohu through the rivers in the city. Assistant factory director Wang Kun said that in order to control the water quality of the nest, Hefei required the sewage treatment plant to upgrade the bidding and upgrade the water quality standard to the quasi -IV.

Excessive use of agricultural pollution such as fertilizer fertilizer is also one of the main causes of lake pollution. Hefei City vigorously promotes green agricultural production methods such as chemical fertilizer pesticide reduction alternatives in the Chaohu Lake Basin. At present, 120,000 acres of land in Chaohu First -level Reserve have been promoted to promote green planting of rice to achieve negative growth in the use of chemical fertilizers.

As a back -up city, Hefei insists on breeding emerging industries with scientific and technological innovation. From the new display to the integrated circuit, from artificial intelligence to new energy vehicles, Hefei has gradually developed a modern industrial system represented by "core screen auto harmony" and "finishing wisdom". Statistics show that in the past 10 years, in the industries above designated size in Hefei, the average annual output value of strategic emerging industries has increased by nearly 20%, and the proportion has accounted for half of the city's half of industries. In 2021, Hefei ’s GDP reached 1.14 trillion yuan. During the same period, Chaohu comprehensive governance surrendered "transcripts": 2020 and 2021 Chaohu State Control Face's annual water quality assessment comprehensively reached the standard. Shuihua is generally declining.

"Economic development, Chaohu pollution does not increase but decrease. Facts have proved that economic development and environmental protection can work at the same time, do each other, and symbiotic and prosperous." Zhu Qing, president of the Chaohu Research Institute.

New policy

In the autumn, the lakes of the lake surged with the wind and the smoke was vast. At the end of this year, the leading Jiangji Huai project will try to pass the water and pilots throughout the board. At that time, 300 cubic meters per second will continue to flow into Chaohu. In the future, these water can also flow into the Huaihe River through the clear water corridor in the Chaohu Lake Basin, providing guarantee for the safety of more than 50 million people in Henan and Anhui.

From the urban lake to communicating the Yangtze River and the upcoming Huaihe River, the Lake Lake governance shoulder the more important ecological strategic mission.

According to data from the Chaohu Administration of Anhui Province, as an important lake in the lower reaches of the Yangtze River, Chaohu accounts for 11.3%of the water area of ​​the lower reaches of the Yangtze River, and the amount of water to the Yangtze River is about 4 billion cubic meters each year. In category Ⅱ.

In recent years, the concept of comprehensive governance of Chaohu has changed from a single water body pollution to implementing the Yangtze River protection strategy and realizing the change of the Chaojiang River. From "the governance of one lake" to the "river basin governance", the new blueprint for the governance of Chaohu is slowly unfolding.

In June 2021, Chaohu was selected as the first batch of "Top Ten Projects for the Integration of Landscapes, Forest, Lakes, Cao Sand Integration and Repairing". According to the plan, Hefei City will basically complete the integrated protection and repair project of the landscapes, forests, lakes and sand in the Chaohu Lake Basin in 3 years.

He Fengyang, deputy mayor of Hefei City, said that at a new starting point, Chaohu will realize the transformation from the quality of water quality to fish and grass, from paying attention to the governance of a lake to protecting the Yangtze River. Chaohu will become a business card for Hefei and be a good ecological barrier in the Yangtze River Delta. (Reporter Yang Yuhua, Shui Jinchen, Liu Meizi, Liu Xiaoyu)
