Xinhua News Agency reporter Liu Shiping
"Eight waters around Chang'an" describes the good water environment of Chang'an (present-day Xi'an, Shaanxi Province) during the Han and Tang Dynasties. At that time, the "Eight Waters" surrounded the outside of Chang'an City, and the city was also full of artificial lakes. With the changes in the ecological environment, the picture of "eight waters as bright as practice" has become history, although "eight waters" exist, but the amount of water is small, the water quality is poor, the channels in the city are wasted, and the water flow is not smooth.
The reporter recently learned from an interview in Xi'an with the interview group of the China Environmental Protection Century Tour led by the General Office of the Standing Committee of the National People's Congress that in the past ten years, Xi'an Has continued to promote the governance of rivers and lakes, especially in 2019, the three-year action plan for the protection and governance of the river and lake system in Xi'an was introduced, and the whole area of water was controlled, the city was rejuvenated by clear water, the eight waters around Chang'an were reshaped, and the good water environment once again returned to the daily life of Xi'an citizens.
The clear bank of the Bahe River is green and welcomed to the new landmark
"Eight waters around Chang'an", just as the double ring is surrounded, there are Huan and Ba in the east, there are Yu and Wei in the south, Feng and Waterlogged in the west, and Jing and Wei in the north.
"Send Junba Ling Pavilion, the water flow is vast." The farewell scene in Li Bai's poem is a daily scene when the Tang Dynasty Baqiao folded willows and the Changting Pavilion bid farewell. Today, the bahe wetland park, which has been treated near Baqiao, is a place for Xi'an citizens and foreign tourists to punch in.
More than ten kilometers downstream of the Bahe River at the site of Baqiao in the Tang Dynasty, the Xi'an Olympic Sports Center is like a huge pomegranate flower blooming on the Bahe River. Unlike the ancient Baqiao parting, the opening ceremony of the 14th National Games will be held here on September 15, and the green Bahe River will welcome the arrival of guests from all over the world. Ten years ago, the Xi'an World Horticultural Expo was held in chanba ecological area, which actually welcomed people from all over the world.
According to reports, in order to control the Chan River and the Bahe River, the Chanba Ecological Zone was specially set up at the confluence of the Chan River and the Bahe River. Before the treatment, the industrial sewage and urban domestic sewage here were almost directly discharged into the Chan River and the Bahe River, and the Chanhe River and the Bahe River became the "urban sewer" that stinked. Later, after treatment, a number of large-scale ecological parks such as Chanba National Wetland Park and Taohuatan Park were established.
Hui Qiang, director of the River and Lake Chief System Work Department of the Xi'an Municipal Water Affairs Bureau, said that since the three-year action of protecting and treating the river and lake water system in Xi'an in 2019, Bahe has planned 16 key treatment projects from the aspects of sewage treatment, embankment treatment, berm forest construction, ecological restoration, and water culture construction. Up to now, the ecological embankment built by the Bahe River has reached 98.4 kilometers, 9 ecological beach areas have been restored, and 2405 acres of berm forests have been planted and transformed.
"The upgrading and renovation projects on both sides of the Bahe River have become a green landscape belt and a riverside water park for citizens to relax and entertain." The water quality of the Bahe River has also been significantly improved, and the water quality of the Bahe estuary has reached the level of surface water Class II. Hui Qiang said.
The Feng River bends with the bend The river flows naturally
The banks of the Bahe River in the east have become a place for citizens to relax and punch in the Internet, and the Fenghe River in the west is no less impressive.
"Guan Guan Ju Dove, in the River Continent." Ladies and gentlemen. "The first poem in the opening volume of the Book of Poetry tells the story that happened in Fenghe. Today, the two banks of the Feng River, which have been treated, also attract many birds, and are also favorite places for young men and women.
In the Fenghe Jinwan Wetland, standing on the Fenghe River Bridge and looking out, the river surface is wide, the river is clear, and birds such as egrets and black storks walk and roost leisurely in the river, or skim the river from time to time, like a waterfront ecological landscape corridor with rural scenery and idyllic scenery.
According to Dang Zhankui, chief engineer of the Xi'an Municipal Water Affairs Bureau, in the process of fenghe river treatment, the river treatment and water pollution prevention and control are closely integrated, and at the same time, the natural river and the artificial canal system are adhered to as the skeleton, bending with the bend, not cutting the bend and straightening, so that the river naturally flows. In the management of the beach area, the original topographic features such as high beaches and deep pools of the river and the original trees are retained, and the natural form of the river is used to create an ecological node.
The Fenghe River All-Index Water Quality Automatic Monitoring Station is located on the south bank of the Fengdong Xincheng River in Xixian New Area, and is used to monitor the water quality of the Fenghe River's inflow into Wei section. The reporter came here to interview, and the monitoring results provided by the staff showed that in 2019 and 2020, the Fenghe River was a surface water class II water quality.
"The banks of the Feng River used to be overgrown with weeds, and the sand dug into the riverbed into potholes, and the banks of the river became garbage dumping sites, and many sewage outlets along the river discharged domestic sewage into the Feng River all year round. In recent years, with the development of the ecological treatment project of the Feng River Basin, the river has become clearer, and a landscape corridor has been built on both sides of the river, which is now a good place for people to relax and entertain. Wang Tuanan, general manager of the Shaanxi Provincial Environmental Protection Company, who grew up by the Fenghe River, said.
The whole area of water and clear water xingcheng "eight waters" has become a river in the city
With the advancement of water control work throughout the territory, the "source of living water" in Xi'an has gradually increased.
"Xi'an connects and diverts water through rivers and lakes, and leads the 'around the city' water system to the moat, Datang Furong Garden, Xingqing Lake, etc., which not only ensures the production and living water, but also reconstructs the urban water system." Hui Qiang said.
As the largest tributary of the Yellow River, the Wei River has a length of 140.6 kilometers and a shoreline of 184 kilometers in Xi'an.
In October 2008, the comprehensive treatment project of the Xi'an urban section of the Weihe River began. After several years of treatment, 184 kilometers of embankment and embankment roof roads and greening construction have been completed. At the same time, the construction of 21 tributaries into the Weihe estuary, represented by the Bawei Bridge and the Bridge of the Jing River into the Weihe Estuary, was completed.
"The comprehensive treatment of the Weihe River has fundamentally solved the problem of flood control in the Xi'an section of the Weihe River, improved the regional transportation capacity, and provided a new leisure and fitness place for the citizens." Hou Jingxin, director of the Weihe Ecological Management Center in Xi'an, said.
After the promulgation of the "Three-year Action Plan for the Protection and Governance of the River and Lake System of Xi'an City in 2019", the three-year protection and governance plan of the Xi'an section of the Weihe River will implement 25 treatment projects such as 6 sewage treatment, 4 embankment treatment, 1 berm forest construction, and 14 water ecological restoration. At present, the governance projects are being implemented as planned.
Dang Zhankui said that since the launch of the work of water control in the whole region, Xi'an City has treated the whole basin of the "Chang'an Eight Waters" and the heihe, xinhe, (yin + soap) river, Qinghe river and Ishikawa river; promoted the construction of the comprehensive treatment projects of the Doumen Reservoir, the Yongpi Lake, the Bailuyuan Reservoir and the moat; and organized the construction of six major projects of sewage treatment plants, water system connection, water conservation, emergency water sources, reclaimed water pipe networks, and smart water affairs. By the end of 2021, strive to achieve the goal of connecting rivers and rivers, connecting rivers and lakes, long streams of clear water, and shallow bottoms of fish.
