The comprehensive treatment of Chaobai River will be launched! The border area of Tongzhou and the three northern counties has changed greatly! Recently, the relevant ** was released"Chaobai River Comprehensive Treatment and Ecological Restoration Project (Tongzhou Section) (Construction) (Supervision) Bidding Announcement". 
According to the approval opinion of the Chaobai River Comprehensive Treatment and Ecological Restoration Project (Tongzhou Section) Construction Project issued earlier, the projectThe estimated construction amount is about 257529 yuan。The starting point of project governanceIt is the Shunyi Tongzhou boundary river traverse station 46+652,Governance endpointsIt is the conductor station 84+188 of the Hebei boundary of Beijing. In addition, in the bidding plan for the whole process of cost consulting services for the Chaobai River Comprehensive Treatment and Ecological Restoration Project (Tongzhou Section), the project will govern the riverAbout 38 km, mainly toThe river embankment in the Tongzhou section of the Chaobai River has been heightened and thickened, the river bottom has been leveled and the river slope has been protected, about 76 kilometers of embankment crest and river patrol roads have been newly built and renovated, and supporting projects such as bank slope greening protection have been implemented simultaneously. 
The Chaobai River Comprehensive Treatment and Ecological Restoration Project (Tongzhou Section) includes flood control engineering, ecological protection engineering, construction engineering, automation equipment and installation engineering, underground pipeline protection and relocation engineering, external power supply engineering, etc. Systematically promoting the comprehensive management of cross-border river basins such as Chaobai River and North Canal is an important task for the construction of high-quality demonstration zones for the integration of Tongzhou and the three northern counties. In accordance with the "Chaobai River Comprehensive Treatment and Ecological Restoration Project Plan".The Chaobai River (Tongzhou Section) will be in line with the "Ecological Green Belt Planning for the Border Area of the Three Counties of Tongzhou and Langfang North".Give full play to the demonstration and leading role of the sub-center of the cityJointly build an ecological oasis represented by Chaobai River National Forest Park with the "North Three Counties" of Langfang CityRealize the ecological scene of water and forest interdependence. 
The Chaobai River Basin is an important ecological corridor between Beijing and Hebei. In 2019, the city sub-center control regulations were issued and proposedSanhe City and Dachang County are bounded by 1 km outside the embankment line on both sides of the Chaobai River, and 2 km outside the provincial boundary in Xianghe County to demarcate the ecological green belt control line in the junction areaThe total area within the Line of Control is approximately 211 square kilometres. Within this range,Coordinate the construction of the Chaobaihe National Forest Park with an area of about 104 square kilometers and build an integrated ecological park chain. In 2023,The "Chaobai River Ecological Green Belt (Tongzhou District and the Border Area of the Three Northern Counties) Plan (2021-2035)" was reviewed and approved, and the regulatory detailed planning of Chaobai River National Forest Park has formed preliminary results. The sub-center greenway connection and quality improvement project was launched, and the construction of the Chaobai River forest ecological landscape belt exceeded 30,000 mu, and the ecological green corridor began to take shape. 
In 2024, Tongzhou will continue to promote ecological integration with the three northern counties. Coordinate the comprehensive management of cross-border river basins such as the North Canal and Chaobai River and the construction of ecological green belts in border areas, and promote the construction of the pilot start-up area of Chaobai River National Forest ParkJointly build an ecological protection belt in the eastern part of the capital. According to Wei Yunyun, deputy director of the Tongzhou District Landscaping Bureau, the total area of Chaobaihe National Forest Park is about 104 square kilometersAmong them, the Tongzhou side is about 60 square kilometers, and the Langfang side is about 44 square kilometers. Around the water veins of the Chaobai River, create a biophilic, high-quality slow-moving hydrophilic ring and a driving scenery ringThree theme gardens for cross-border synergy will be built: Tongyan Sports and Fitness Park, National Botanical Garden, Chaobai Nature Education Park and 21 inscribed landscapes along the line, and at the same time radiate Yanjiao, Dachang and Xianghe in the three northern counties. The construction of the pilot start-up zone is scheduled to start by the end of this year. It is also understood that around the construction of the Chaobai River National Forest Park, relying on the good ecological resources of the North Canal and the Chaobai River, a large-scale ecological oasis will be built in the central area of the two rivers. Tongzhou District and the three northern counties are "centered on the continent", bringing together major water system corridors and transportation ecological corridors such as Chaobai River, North Canal, Baoqiu River and Lu River; Along the Chaobai River, North Canal and other major corridors, a total of 5 regional greenways will be built. These recreational greenways start from the sub-center and connect the three northern counties, stringing together the ecological pattern of blue and green.
