Chinese name: The North Canal belongs to the tributary of Haihe River and flows through the eastern suburbs of Beijing and Tianjin. Ancient name: the upper reaches of the Baihe River: Wenyu River originated from: the southern foot, the Beijing section, and the length of the river: Lu? Yan? Hebei Duan Hechang: Wang Xiaodong? River profile, water conservancy project, historical evolution, transformation, urban construction, introduction of scenic spots and river profile: Dongsha River, Beishan River and Nansha River are tributaries in the upper reaches, which are called Wenyu River after the confluence of Shahe River, and Yun Bei River when it flows to Beiguan of Tongxian County in the southeast. The south flows through Niumutun Village of Tongxian County, leaves Beijing, enters wuqing district of Tianjin via Xianghe County of Hebei Province, and joins Haihe River at Dahongqiao. Total length 180 km. The basin covers an area of 5,800 square kilometers. The river in Beijing is 38 kilometers long. The basin covers an area of 4,423 square kilometers. The river width is generally between 50- 100 meters. The main tributaries are Qinghe River, Bahe River, Liangshui River, Tonghui River and Fenggang River. Because the upstream tributaries mostly come from mountain springs and rock fissure water, the water volume is generally small, the riverbed is straight and narrow, and the flow velocity is gentle. The water conservancy project is the northern section of the Beijing-Hangzhou Grand Canal, and it is an artificial water conveyance channel dug by the Sui Dynasty in history. Guo Shoujing, a well-known hydraulic scientist, once led Baifuquan in Changping County to Shuiwengbo, passing through Gaoguo River (now a long river), North Moat River and Tonghui River, so that water carriers could reach the docks in Jishuitan, the capital of Yuan Dynasty. Finally, it was abandoned because of insufficient water and shallow siltation in the river, and it was often flooded because of poor drainage in the river. According to the records of Tongxian Hydrological Station 1939, the peak flow reaches 1670 cubic meters per second, which makes the river overflow. After 1959, more than ten small and medium-sized reservoirs, such as the Ming Tombs, Xiangtan, Wangjiayuan and Taoyukou, were built in the upper reaches, which basically controlled the flood disaster. Now it is the main drainage channel in the urban and suburban areas of Beijing, and it is also the water delivery channel for agricultural water in Tianjin. 1963 Excavate tidal channel to reduce flood and flow into Chaobai River. 1970 for dredging, and the flood discharge conditions are improved. Sluices such as Beiguan, Zhuang Lin and Yangwa in Tongxian County have been built on the North Canal, which can store 20 million cubic meters of water at a time and control the irrigation area1.4000 hectares. The North Canal is the main channel of Haihe River system, which integrates flood discharge, Luanhe River diversion and water diversion. The renovation started in April, 20001year and was completed in September. Qujiadian Gate to Zibei Interchange 15.0 17 km, shore distance 120 m, total length of messenger wire 30.032 km. The North Canal has clear water and green shore, bright lights along the line, smooth flood discharge, convenient transportation and elegant environment. It is an effective combination of water conservancy projects and landscape projects, and it is a beautiful landscape in our city. North Canal 2065438+On July 22, 2007, Beijing announced the "enhanced version" of the river length system, and publicized 18 the list of Beijing-level river lengths: Yan Lu is the city-level river length of the North Canal. Historical Evolution The North Canal is an important waterway leading to Beijing in history. It starts from Tongzhou District, Beijing in the north, flows through Wuqing County, Nalongfeng River and Huidong River in Tianjin, reaches the new Huidong River in Qujiadian, Beichen District, reaches Guoxinzhuang and Qianlidi, enters Hongqiao District, flows through the northeast edge of Hongqiao District, reaches Huiziya River in Donghongqiao, and joins the South Canal at Sanchahekou to enter Haihe River. Total length 186 km. The reach of Hongqiao District is about 6 kilometers long and 60-70 meters wide, with a maximum flow of 100- 184 cubic meters per second. From northwest to southeast, it is Beichen District. The boundary river between Hebei District and Hongqiao District. It flows through Xianyang North Road, Tinggu, Xigu and Santiaoshi. There are scenic spots such as Taohuayuan and Xigu Park along the coast. Sanchahekou has a monument to the Luanhe River Diversion Project, Youtan Ferry along the river, Qinqin Bridge, Beiyang Bridge, Xinzhuang Bridge, Battery Ferry and Santiaoshi Pedestrian Bridge. During the Yongle period of the Ming Dynasty, water transportation was developed and Tianjin developed into a commercial port. The canal played a certain role in the economic and cultural exchanges at that time. In addition to shipping, rivers are also the source of life for urban and rural people. Because the northwest of North China is high and the southeast is low, the upstream slope is steep and the downstream plain channel is tortuous and muddy, floods have occurred many times in history. At present, rivers in China are used for flood discharge and water storage. The historic North Canal is an important waterway leading to Beijing. It has made historic and important contributions to the formation of Tianjin city and the prosperity and development of agriculture, industry and city. With the acceleration of urbanization and population growth in Tianjin, the ancient canal bears a heavy burden: houses occupy dikes, the riverbed is polluted, it is in disrepair for a long time, its functions are sharply reduced, and garbage mosquitoes and flies breed, which seriously threatens the water quality of Luanhe River, affects people's lives on both sides of the strait, and seriously damages the image of Tianjin city. After vicissitudes of life, the North Canal lost its former glory and almost became an abandoned river. From June 5438 to February 2000, Tianjin comprehensively managed the North Canal. Nine months later, a new canal full of vitality appeared in front of the world. Urban construction "comprehensive management of the North Canal" is the first step for Tianjin water resources department to shift its focus from rural areas to cities. It is the first exploration to change the previous river regulation only considering flood control function and realize the extensive expansion of water conservancy engineering function. The North Canal can meet the needs of flood control and water transportation as well as the urban environment through greening, beautification and the construction of human landscape, and through the comprehensive management of dikes, forests and roads. Wang Hongjiang, director of Tianjin Water Conservancy Bureau, explained to reporters the significance of the comprehensive management project of the North Canal. With the acceleration of the construction of a modern international metropolis in Tianjin, the economic and social development and the improvement of people's living standards put forward higher requirements for the urban environment. * * * Member the Political Bureau of the Communist Party of China (CPC) Central Committee and Secretary of Tianjin Municipal Party Committee * * * demanded that "the water in urban rivers should be turned into clear water and flow, so as to change the overall appearance of the urban environment and make the urban environment cleaner, more beautiful and more pleasant". The water conservancy department decided to take the North Canal regulation project as a pilot, implement the requirements of the city leaders, organize engineering designers to visit and study in Beijing, Shijiazhuang, Chengdu and other places, put forward the canal regulation plan, actively explore the development of water conservancy projects from single function to comprehensive function, and explore new ideas of water control from traditional water conservancy to modern water conservancy and sustainable water conservancy. In the comprehensive project management of the North Canal, Tianjin water conservancy department deepened the reform, actively explored new ways of water conservancy project management in metropolis, set up property management economic entities in project maintenance, and established a management model of separating managers from nutrition institutions. According to the different types of water conservancy projects, dikes and parks, economic entities are established respectively. The bidding system is implemented, and the daily maintenance content is outsourced at a fixed cost. The economic entity shall be selected on the basis of merit, and the two parties shall sign an agreement to ensure the project quality. In the daily maintenance, managers should patrol and inspect according to the post responsibility system, and urge them to do a good job in management. If the daily maintenance is not in place, in addition to the implementation in accordance with the requirements of the agreement, the responsibility of the management personnel should be investigated to form a good operating mechanism. Under the premise of ensuring flood control, the comprehensive management project of the North Canal in the city's water conservancy scenic spot comprehensively transforms dikes, forests and roads. The whole landscape uses new landscape composition techniques and landscaping theory, which has both unity and contrast in zoning. It takes city, environmental protection, leisure and entertainment as the overall creative framework, and ecological leisure-winter song, hydrophilic leisure-autumn love, cultural leisure-summer dream, healthy leisure-sound of spring. Introduction to scenic spots The North Canal is responsible for flood control and Luanhe River diversion. Tianjin 200 1 implemented the comprehensive management project of the north canal with a total investment of 470 million yuan. Four theme parks, namely Luanshui Park, Beiyang Park, Yu He Park and Recreation Park, will be built, with rubber dams 1 seat, 3 bridges and 8 docks1seat, and 900,000 square meters of green space will be added, with a total area of 265,438+. After comprehensive management, the North Canal has a clear shore, smooth flood discharge, elegant environment and rich tourism resources, and has become a beautiful landscape. Four theme parks, Luanshui Park, Beiyang Park, Yu He Park and Leisure Park, have been newly built on both sides of the North Canal. The whole Luanyuan Garden is composed of "miniature landscape of drawing Luanhe River into Tianjin", "urban gathering landscape" and "flowery flowerbeds", spanning the whole sculpture and the street landscape of Luanhe Exhibition Hall Square. Beiyang Garden is a main line of "traditional ideas are fixed in history" and "educational spirit is rooted in people's hearts". Yu He Garden consists of seven parts: relief landscape wall, landscape, floating dragon, flowing water, poetic road, legendary road, ancient anchor and antique wharf. The amusement park consists of bunkers, decorative columns, music revetment, decorative revetment, interesting accessories, son of the canal and hope. There are more than 5,300 trees and shrubs in the Peach Garden built on the north river bank, including more than 500 peach trees, including peach trees, peach trees and longevity peaches, which are full of spring when in full bloom. Beiyang Bridge Qujiadian Wharf 10, cruise ship 13 km. Every spring to autumn, tourists can board a boat to visit the beautiful scenery along the way.
