Ten wetlands wear "emerald necklace" for Chaohu

Ten wetlands wear "emerald necklace" for Chaohu Lake

In summer, driving along the fifth largest freshwater lake in China, not only did you smell the smell of the epidemic of cyanobacteria in previous years. The borderline, the lotus blooming lotus, and sometimes the egrets of the beautiful arc in the blue sky.

At the end of July 2022, with the implementation of the last process of the Third Phase of Feidong Eighteen Lianxian Wetland, the top ten wetlands around Chaohu Lake were fully completed. 10 wetlands set up a natural ecological barrier for Chaohu Lake.

"Some people say that the shape of Chaohu is like the legendary 'cornucopia', and the completion of the top ten wetlands is equivalent to putting a string of" emerald necklace 'for' cornucopia '. " Top ten wetlands with a total area of ​​100 square kilometers and a total investment of 5.85 billion yuan have been completed. Hefei has accumulated exploratory experience in the treatment of water body management of inland freshwater lakes, and will drive leisure agriculture and rural tourism development around the nest lake to help the countryside Revitalize.

"Combination Boxing" helps push wetland repair

On the afternoon of August 23, at the request of several tourists, Zhou Xinmin drove them to Sanyhe Wetland to take pictures.

Sanhe wetland is close to the nest lake shoreline, which maintains the original shape of Tianyu, Gully Pond, and Quartts. Ecological green tract string small and micro wetland science science districts, farming culture exhibition areas, leading river Jihuai tour area, Taipingyu ecological experience zone and ecological agricultural gathering area Wait for different areas. The rough and primitive scenery of the wetland caught tourists from time to time.

Zhou Xinmin was a local farmer. In order to build Sanhe Wetland, he returned farmland with the villagers and opened a homestay in Sanhe Town.

Wetland is called "the kidney of the earth". For 800 miles, the wetland of the lake is the "kidney" that maintains its ecological environment.

In recent years, Hefei has promoted the comprehensive governance of Chaohu in the city. In 2018, Hefei officially launched the top ten wetland protection and restoration project around Chaohu Lake around the core issues of wetland protection such as habitats, water systems, water quality, and water volume. So far, Ten major wetlands such as Paihekou, Lake Bin, Sanhe, Huailin, Laodao River, Qifengzhou, Mawei River, Jade Belt River, Peninsula, and Eighteen Lianxian have been fully completed.

Hefei adheres to the combination of natural recovery and manual repair, adopting measures such as ecological hydration, breeding, returning farmland and wetness, vegetation recovery, protecting wildlife, immigration relocation and other measures to build a leading domestic lake wetland group. Hefei took the lead in starting the ecological governance project of the lower reaches of the fifteen miles of Chaohu Lake, purified water quality, cut nitrogen and phosphorus, implemented 15,000 acres, returned 47,000 acres, retreated to 7005 households, and resumed 65,000 acres of wetland. A total of 410,000 trees, 3.354 million square meters of shrub, and 9.06 million square meters of aquatic vegetation.

In Binhu Wetland, the reporter walked into the Candal Science Popularization Pavilion, which is located in the west river algae water in the bank of Chao Hubei. Here, you can see the enlarged cyanobacteria structure model that has enlarged many times. Through the equipment in the science pavilion, you can understand the past life and structural characteristics of the cyanobacteria. Harm.

Nowadays, the built -in wetland groups are realizing the main functions such as improving water quality, water storage flood prevention, and maintaining biodiversity. The average daily purification water volume of the top ten wetlands can reach 1.2 million tons. In 2020, the ten wetlands of the Lake Lake cumulative flood storage of 269 million cubic meters, the maximum reduction of the water entry water. The survey shows that there are 562 species of plant plants around the lake and 303 birds. More and more rare birds such as white ravioli, white spoonbills, red -breasted autumn sand ducks are selected here.

"These birds were common when we were young. For a few years, people and villages were crowded by the lake, and the birds were gone." Therefore, the soil was difficult to leave. The big trees that are filled with white crickets are the original village entrances, can it be like oil painting? "

In June 2022, the second batch of international wetland cities were announced. A total of 25 cities in the world won this honor, and Hefei ranked among them.

Rare birds appeared in Chaohu successively

In the midsummer, Feidong Eighteen Lianxian, the water and grass are rich, and from time to time, flying birds pass through the sky.

This is the Changlinhe 2814 fishing ground with a history of more than 30 years. Now it has changed the appearance of the past -33 "Ecological Filter Islands" is the biggest highlight here.

Overlooking, these "ecological filtration islands" of these different sizes are high -pollution bottom mud of the 533 fish ponds in the fascinating area. This is the result of centralized solidification and scientific governance through ecological filtration islands. According to this, after the South Lang River water enters the eighteen united wetlands by self -current, after purifying the dotted wetland in the west and the Dutdo Wetland in the east, it is remitted into the central lake wetland for in -depth purification, and then the pump station is discharged.

Walking through the wetlands, the rivers are vertical and horizontally; "We have built a variety of wetland habitats including ecological islands, seasonal grass beaches, wet grass, beaches, Luzhu swamps, shallow water areas, and deep water areas, forming a good wetland ecosystem structure." Li Jiazheng, executive deputy general manager of Construction Management Co., Ltd. said.

In Lujiang County, Qifengzhou Wetland and Mawei River Wetland are beautiful and extraordinary. "In 2019, we repaired and reconstructed the four plots including Toyo, Yilang, Xuqiao Lianyu, and Cangtou Lianyu in the two wetlands of Qifengzhou and Mawei River, with an area of ​​5097 acres. The restoration project was completed at the end of March last year, and then transferred to the daily maintenance stage. "Shao Jian, a staff member of Lujiang County Forestry and Garden Construction Service Center, introduced. Following the direction of his fingers, the reporter saw that the aquatic plants such as reeds, crickets, lotus, lotus, crickets, releas, and Cugu built a healthy wetland ecosystem with improvement of water environmental quality, improvement of biodiversity, and science science pronunciation. Walking along the Chaohu Avenue, the sky, the wings of the birds pass by from time to time; the beach on the beach, the egret walks elegantly, the wild duck quickly slides ...

After the seventy -year -old Xia family retired, she carried a camera to the Chaohu Lake almost every morning to turn around every morning. The camera recorded many birds that were not recorded in the history of Chaohu Lake. "Over the years, the area of ​​wetland has expanded, the quality of the nest lake has improved, and the number of fish and shrimp after the ban is banned. The Chaohu Lake has gradually become a bird of birds.

"Rare birds appeared and inhabited in Chaohu one after another, reflecting the increasingly better ecological environment of Chaohu Lake." Yu Lei, a bird expert of the Biological Resources Survey Project Team of Chaohu Lake, said that since this year, the Birds survey of the Chaohu Lake recorded a total of birds. There are 257 species 56. "There are 13 new records of birds around the Chaohu Lake, of which Western chickens, brown -headed gulls, Asian short -toed Bailing and long mouth are new record bird species in Anhui Province, and the white pelicans are new record bird species in Hefei."

The wetland construction has pretended to be the beautiful scenery of the Chaohu Lake's "Three Sides of Qingshan and the Lake". More and more local citizens and foreign tourists gathered around Chaohu to gain a significant sense of gain and happiness.

Comprehensively apply the strategy to build a good wetland

How to protect wetland? How to repair? How to manage long -term management?

In 2019, Hefei opened the first protection of wetland legislative pioneers and issued the "Decision of the Standing Committee of the Hefei Municipal People's Congress on Strengthening the Protection of Top Ten Wetlands of the Chaohu Lake" to inject the power of rule of law for the protection of the wetland of the Chaohu Lake.

Hefei also made a breakthrough in the wetland compensation mechanism and wetland protection and repair mechanism, and formulated the "Methods (Trial)" for the "Top Ten Wetland Ecological Evaporation Ecological Evidence Ecological Evaporation Ecological benefits (trial)" to implement the financial awards policy. The "Protection and Repairing Technical Guidance of Wetland Wetland in Chaohu Lake" enriches the restoration measures of wetlands; introduced "Top Ten Wetland Pipe Guide to the Chaohu Lake (Trial)" to promote wetland protection and repair.

The wetland should be built well, and we must take care of it. "With the comprehensive completion of the top ten wetlands of the nest lake, the focus of the later period is to control." The relevant person in charge of Hefei Forestry and Gardening Bureau said that since 2022, Hefei will be 3 years in a row, with a budget of about 85 million yuan each year. It is used for compensation for ecological benefits of the top ten wetlands around Chaohu Lake, and constructing a long -term mechanism for the development of wetland later stages.

Walking in Chaohu Lake Bin National Wetland Park, park maintenance and managers in uniform uniforms can be seen everywhere. "In order to ensure the efficient operation of the park, the district innovation adopts the" government+state -owned enterprise "model for operation management." Wang Hao, head of the transportation management department of Chaohu Lake Bin, said that the park is now equipped with more than 220 people in management, patrol, and maintenance personnel. Realize normalization, specialization, and refined management.

At the Mission Hall of Sanhe National Wetland Park, on a large screen, data such as the temperature of wetland, precipitation, wetland functional partitions, and animal and plant types are clear at a glance. As the first "national" wetland park in Hefei, Sanhe National Wetland Park has gone ahead in scientific research monitoring. "We cooperate with the School of Resources and Environmental Engineering of Anhui University to carry out long -term monitoring of the vegetation coverage and land coverage of wetland parks and land coverage." Sanhe National Wetland Park Management Center staff introduced.

"Monitoring is like a" physical examination ", which aims to better control and play a good function of wetland." Hefei Forestry and Garden Bureau relevant person in charge said that the next step in Hefei will build a wetland smart platform and continue to carry out the biological resource survey of Chaohu Lake Study and wetland ecological monitoring, scientifically evaluate the effectiveness of wetland repair, realize the sharing and action synchronization of the top ten wetland data, and establish a database database and ecological early warning mechanism for wetland resources.
