Xiong'an New District Painting Platform Water City to integrate the ecological picture

Xinhua News Agency, Shijiazhuang, July 13th. The Hebei Provincial Department of Ecology and Environment recently released news that on the basis of ensuring that Baiyangdian's water quality is maintained, it will pay more attention to biodiversity and promote governance targets from "water environment quality" to "water ecological health" change.

On the banks of Baiyangdian, a new city is growing up. With the establishment of Xiong'an New District, Bai Yangdian, a "Pearl Pearl", which was once polluted, also reappeared vitality and entered the ranks of good lakes across the country. A harmonious coexistence of people, water, birds, and fish, fresh and bright ecological scrolls in the water city are presented in front of people.

From pollution to governance

A sewage treatment station is not far from the village entrance. The village cadre Wang Yawei said that in the past, various domestic sewage in the village was arranged in the sediment. Nowadays, all households have been connected to the pipe network uniformly, and the domestic garbage is clear.

Baiyangdian is the largest freshwater lake in the North China Plain, and has the reputation of "Pearl of North China". However, for a long time, due to the sewage discharge of upstream enterprises and the direct discharge of domestic sewage in the villages of the villages, the water pollution of the Baiyangdian waters has become increasingly serious. At the beginning of the establishment of the Xiong'an New District in 2017, the water quality of Baiyangdian was inferior to the V.

The Xiong'an New District, which carries the "Millennium Program and the National Event", has a natural ecological advantage because of sitting in Baiyangdian. The restoration and protection of Baiyangdian's ecological environment has also become a major proposition for the planning and construction of Xiong'an New District.

Baiyangdian ushered in the largest systemic ecological governance ever in history. From the perspective of "one game" in the global basin, it adheres to the "control source -intercepting pollution -governance" integration. The water quality improves one year: Class V at the end of 2018, at the end of 2019, class IV at the end of 2019, and at the end of 2021, category III, and stabilized in class III in the first half of this year.

The reporter found a interesting phenomenon when exploring many governance measures: some "old traditions" that Bai Yangdian lost his passing. The people have the habit of digging the mud since ancient times, which can not only purify the quality of the water, and the mud can also be used as the fertilizer of reed fields. In the past few years, local fishermen raised fish, planting ravioli, and putting bait and pesticides, resulting in severe sludge pollution. Nowadays, ecological dredging is organized organized, and the sludge is inhaled into the pipeline of the twisted ships to concentrate purification.

Near Duancun, Anxin County, the water excrement of the water excavator was cleared to block the width of the water. A ship that salvaged the debris traveled through, and an "Baiyian Unicom" project was underway.

Of course, the reporter feels more of the power of technology. In the estuary area of ​​the river, the near -natural water purification process of "front precipitation ecological pond+submarine wetland+aquatic plant pond" is used to build an ecological barrier, which is equivalent to installing a set of "purifiers"; The "Heaven and Earth Integration" ecological monitoring ship is working, and the water quality monitoring equipment on the ship can achieve rapid analysis of 14 water quality indicators.

From quiet to moving

In the summer of Baiyangdian, the reeds of the formation are lush and full of green.

Bai Yangdian has said that "one stroke reed and one stroke" has been said since ancient times, but with the change of production and lifestyle, the people rarely harvest reeds. Zhang Xiaolong, a cadre of the Agricultural and Rural Bureau of Anxin County, introduced that the growing reeds have the effect of purifying water quality. If it is not harvested on time, it will cause degeneration. After the residual body is corrupt, it will even affect the water quality.

Nowadays, there are nearly 100,000 acres of reeds. The Xiong'an New District implements a "balanced harvest": half of the annual harvesting area, and the villagers receive 120 yuan for each acre of the government.

The "Hebei Xiong'an New District Planning Outline" proposes: "Native aquatic vegetation in the regional degraded area, promote the proliferation and types of indigenous types of aquatic animals, restore and protect bird habitats, improve biodiversity, optimize the ecosystem structure, enhance Baiyangdian ecological ecology Self -repairing ability. "

As Baiyangdian's ecological environment continues to improve and birds and birds protecting birds have become social consensus, the "bird paradise" victory is presented in front of people. At present, the number of Baiyangdian bird species has reached 237, which has added 31 species from the Xiong'an New District. Among them, there are 10 types of birds in national first -level protection and 43 national second -level protective birds. "The quality of the water is good, and the catfish returns to the storage again." Said Zang Peijun, deputy director of the Agricultural and Rural Bureau of Anxin County, said that this is the indigenous fish species of Baiyangdian. However, it has high requirements for water quality, and once disappeared in the storage.

As of the end of 2021, the Baiyangdian Basin has implemented more than 270 million units of proliferation and release seedlings. At present, Baiyangdian fish has returned to 46 species, adding 19 more compared with the establishment of Xiong'an New District. The latest assessment of the Institute of Marine and Aquatic Sciences in Hebei Province is: Baiyangdian fish biological diversity has reached a high level.

At present, Xiong'an New District is planning to conduct a comprehensive investigation of Baiyangdian, find out the level of ecological environment and biodiversity, and further clarify the goal of the protection of Baiyangdian wetland construction. "If the quality of water is a kind of static beauty, then harmony between man and nature is a dynamic beauty." Said Tian Yongchang, deputy director of Anxin County Natural Resources Bureau.

From a separate to Rong

"There are lotus red reeds, birds and fish jumping ... The meals in our village have iron pot stewed fish, crispy green shrimp, cold lotus leaf buds, fried lotus, oil burst field snails ..." Wang Hui stood on the side and started another live broadcast.

There are 15 farmhouses in this village, and many villagers have become "Internet celebrities" anchors.

According to the planning of the Xiong'an New District, the city and the dden must be harmonious and coexist, and finally realize the integration of water cities.

The start -up area with a planned area of ​​38 square kilometers is the first area of ​​Xiong'an New District. The central Green Valley in the middle is 13 kilometers. The two sides are wide forest belts, and the water system is in the middle. The three artificial lakes are designed. The entire water system has recently been connected to the water to achieve the connection with Baiyangdian.

"Water City is like a water village in the south of the river. The traditional characteristic buildings on both sides of the streets are different. The beautiful appearance of Anxin District.

In the past, due to the drought of the climate, the decrease in water from the upstream, and the increase in the amount of water for industrial and agricultural, the water level of Baiyangdian continued to decline, the phenomenon of severe drought and dry stroke was frequent, and the area continued to narrow.

At the wetland of the Baiyang Dianfu River, a large number of prosperous plants and trees were intertwined with the staggered waterways, and from time to time, birds sounded. This important ecological barrier was used to be a large crops.

According to reports, the Xiong'an New District implements the return farming and repayment, and the multi -water source hydration mechanism is established. The water level of the sediment area is stable at about 7.2 meters, and the area is recovered from about 170 square kilometers to about 290 square kilometers.

According to the plan, the comprehensive governance of Baiyangdian will be fully completed by 2035, the ecological environment of the Dian District will be fundamentally improved, and the benign ecosystem will basically recover. Bai Yangdian's ecological restoration is still far away.
