Hefei these ten years | Plaster green water and green mountains ecological background

Chaohu, known as "eight hundred miles of lake sky". Thousands of blue waves, Lianhuai Tongjiang, as if a pearl was embedded in the land of splendid.

In 2011, Chaohu officially became the Neihu of Hefei. "Holding the lake into the arms" has opened a new situation of the symbiosis of the city and lake; the ten -year governance has made Chaohu Lake the "best business card" in Hefei; for a long time, it has brightened the ecological background of the "green water and green mountains".

Ten -year governance show

After ten years of continuous practice exploration, Chaohu comprehensive governance has transformed from "Kowloon Water" to "harmful water management", from "one lake governance" to "river basin governance", and from "pollution prevention" to "ecological governance". The system promotes the five major projects of "blue water, Anlan, ecological restoration, green development, and sharing of the people". The cumulative investment of 5.85 billion yuan and a total planned construction area of ​​100 square kilometers "Top Ten Wetlands" is fully completed, and it has built the ecology of the nest water water ecology, and Water safety barrier.

Ten years back, Chaohu comprehensive governance has gone through three stages:

——In 2012 to 2016, the comprehensive management of Chaohu starts with flood prevention and pollution control, reducing flood disasters around Chaohu, controlling and reducing the load of pollution in the lake;

——In 2017 to 2020, the comprehensive governance of Chaohu began to expand the content of governance from the line to the face according to the small basin governance concept of "river basin planning, systematic thinking", expanded from the river to the basin, and explore the pilot demonstration of the watershed governance;

——In 2021, Chaohu Comprehensive Management has taken the implementation of the country's first batch of "the integrated protection and restoration projects of landscapes, forests, lakes, and grass and sand", and began to advance to system governance and strive to explore the Chaohu model of the symbiosis of the city and lake.

Nowadays, the average water quality of the whole lake has shifted from the inferior category in 2015 to Class IV, and it was once improved to Class III in 2020. The best level of monitoring records in 1979; The monitoring of the cyanobacteria water time was May 30. Compared with the same period of 2020, the first monitoring of the cyanobacteria water time was delayed for 56 days; the wetland ecological function was further improved, and the biodiversity around the lake recovered steadily. The total number of birds with records of the coast has reached 303 species, and 6 new birds were discovered this year. The national treasures such as Dongfang Baiyu, Qingsou Qian Duck, and Black Face Berbill are regaining Chaohu; in June last year, the three national ministries and commissions announced the "Top Ten Projects of System Governance of the Grass Sand System of Landscapes, Forests, Lakes,". Lake.

The nest governance scrolls with the green scenery of the clear shore of the water reflect the determination and courage of Hefei to keep in mind the "big of the country" and adhere to the "four sources of the same governance".

Candida Water Hua has always been the difficulty of the governance of Chaohu Lake. As soon as the weather is hot, the cyanoscoules will grow crazy.

Jiang Qingquan and his sunset red volunteer service team are a professional "cleaning team" active on Chaohu Lake. They have guarded the Chaohu Ecology for 15 years, and the number of people in the service team has gradually grown. "Now the environment is getting better, all kinds of birds, fish and shrimp in the lake, and more tourists. We will continue to guard in the future, making the nest lake better and better." He Full of confidence.

"In the past, standing on the shore, you can smell the pungent smell from the cyanobacteria. From a distance, the water is green, and the boat cannot be faster." Xu Yegui of the Lake Lake Cando Salvation Team said, "Now there are we manually Cooperate with 'Candida Salvation Black Technology', the lake ecology is a lot better. "

I saw a large boat slowly on the lake. The algae water was inhaled from the bow from the bow, and the clear lake water flowed into Chaohu from the stern. This is the magnetic catcher of "Salva Salva Salva". After being salvaged, the cyanobacteria was put ashore and put it into the integrated pump room. After dehydration of algae water separation from port, part of the algae mud was sent to the power plant to generate electricity, and the other part of the biological fertilizer was made through scientific treatment.

At present, Hefei has built 5 algae separation stations along the lake with a processing capacity of 18,000 tons/day. It is also equipped with more than 160 main salvage vessels in the magnetic catcher and shallow water area.

Compatible with the construction of emergency response facilities in cyanobacteria, Hefei issued the "Chaohu Lake Emergency Prevention and Control Data Information Management Plan" to establish a platform for data information information information on Chaohu Lake, integrate multi -channel data information such as monitoring, inspections, inspections, prediction and early warning, etc. Regularly compiled the "Chaohu Lake Calcocarius Monitoring and Forecast Weekly", inspect the Chaohu Lake District and drinking water sources every week, organize special force to inspect the status of the cyanobacteria along the lake every day, and timely release and report the inspection of the cyanobacteria. At present, the emergency prevention and control system of Chaohu Lake Lake Lake has been established. As of July 21 this year, Chaohu has no obvious cyanobacteria.

"I like to welcome the wind to stand by the lake. The air is full of the fragrance of grass and wind in nature." Fang Qing, a tourist who came to Chaohu Lake, opened his arms, seemed to want to embrace this lake and mountain.

A line of egrets on the sky

Sand gull's collection, Jinchin swimming, in the vast smoke waves of "Eight Hundred Miles of Lakes", all things compete for freedom.

"In 2016, we found three oriental white sturgeons in the Wetland Park of the Chaohu Peninsula. The number of populations that migrated last year had reached thousands!" Speaking of the birds of Chaohu Electric Power Company, Qian Mao Song The famous bird lovers, he rooted in the lake and recorded many rare birds.

The autumn is high, and many unknown birds flew towards the blue sky, as if there is a trend of "a row of egrets on the sky". Many photography enthusiasts gather here to record Damei Lake on the camera.

Bird Grand Panda "Oriental White Burmese", endangered waterbird cotton, "red -legged lady" black wings long feet ... As a "chasing bird" for ten years of qualifications, Qian Maosong obviously feels the expansion of the wetland area here. Attracted more birds with rare varieties. "There are millions of migratory birds in the nest of Chaohu in the autumn and winter to the following spring. In recent years, the ecological environment is getting better and better, and migratory birds have also fell in love with this music." The wetland of migratory birds is called "the kidneys of the earth". For Chaohu, the wetland around the lake is the "kidney" that maintains its ecological environment. The wetland lives, and the ecology is resting.

As one of the main input channels of Chaohu Lake, the Wetland Wetland of the Fifteen River has gone through a "gorgeous turn". The fifteen miles were once a river with water quality all year round. The sewage treatment capacity of domestic sewage in the basin was insufficient, and the mixed flow of rain and dirt was multi -faceted.

Governing the river first. Hefei launched the nest -first -level tributaries of the fifteen miles downstream river estuary ecological governance project to purify water quality, cut nitrogen and phosphorus, and accelerate the implementation of the project, pay close attention to daily supervision, and improve the water quality improvement of the fifteen miles. OK. From 2019 to 2022, the water quality of the Fifteenth River for investigating the surface was stable to the surface water III, and the water quality was improved.

In 2018, Hefei launched the top ten wetland protection and restoration project around the nest lake around the core issues of wetlands such as life, water system, water quality, and water volume. Ten wetlands such as Paihekou, Lake Bin, and Sanhe have fully completed the repair. Overlooking the high altitude, the top ten wetlands seem to wear a "emerald necklace" for Chaohu Lake.

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. Up to now, the wetland repair area of ​​97.1 hectares, forest and grass and other vegetation ecological ecology covered with a green area of ​​14.7 hectares, the length of the restoration of the bank embankment was 13.7 kilometers, the area of ​​water pollution treatment was 41.1 hectares, the area of ​​soil and soil loss was 23.5 hectares, and the area of ​​biological diversity protection was 166.1. Hectare, all super target progress.

Zhou Xiaochun, director of the Wetland Management Department of the Anhui Forestry Bureau, once said that Hebei vigorously implemented the 10th wetland protection and restoration project around Chaohu Lake, with remarkable ecological benefits, and has good innovation and demonstration in the country. Nowadays, tourists from all over the world "punch cards" Chaohu, watch the reeds swaying on Chaoshan Island of Chaohu Lake, Qifengzhou, and the setting sunbird.
