At the cruise ship dock of Beijing Zoo , there is a sign that says "Looking at the Temple of Heaven, watching the willows in the long river, the Royal Imperial River, and the time and space painting scroll." The long river mentioned here includes the Nanchang River.
The long river is the water diversion river in the capitals of all dynasties. During the Qianlong period of the Qing Dynasty, the long river was dredged and repaired and became a special waterway for members of the royal family to travel from the Forbidden City to the western suburbs such as the Summer Palace and the Old Summer Palace. Therefore, it is also called the "Royal Imperial River". The long river is divided into two sections: North Changhe and South Changhe. The long river we are talking about now usually refers to the Nanchanghe. It starts from the Changhe Gate, flows through Maizhuang Bridge, Guangyuan Gate, Baishi Bridge , and reaches Beizhanhouhu Gate and connects to the river and enter North Moat . The total length is about 5.08 kilometers.
Old Beijing has a saying that "seeing the pine tree in the Temple of Heaven, and watching the willow tree in the long river". Every spring, green willows are shady on both sides of the river, and the shadows of trees are swaying like curtains. Many people come here to enjoy the scenery in spring, which has gradually become a custom.
"In the early years, the Nanchang River actually did not have as much water as it is now." Liu Jikun, deputy director of the North Ring Road Management Office of the Beijing Urban River and Lake Management Office, told reporters that before 2008, the water resources in the Nanchang River were in short supply, and the water flow in the river was poor, and the water blossom phenomenon often occurred. In order to make the river flow, the North Ring Road Management Office installed the lifting pump at the Ziyuwan ship lock in the middle of the Nanchang River. The downstream water is lifted upstream through the pipeline and then lowered along the river channel to achieve the effect of circulation.
After several years of flood season, the water quality of the Nanchang River increased by Jingmi water diversion canals and Kunyu River . The North Ring Road Management Office also used the Ziyu Bay ship lock and the water transfer tunnels on both sides to continuously transport water downstream, and the water quality of the Nanchang River gradually improved. With the full implementation of the " river chief system ", the River and Lake Management Office has strengthened contact with local streets and water pipe units along the Nanchang River, increased the intensity of river inspections, and the water quality has become clearer and has now reached the standard of surface water Class III.
Many people don’t know that Nanchang River is actually the main water supply channel for rivers and lakes in Beijing. “Half of the water in the Nanchang River flows into the rivers and lakes in the inner city, such as Xihai, Shichahai , Qianhai, Beihai, Beimo, etc., all replenish water sources through the Nanchang River.” Liu Jikun told reporters.
Near the North Ring Road Management Office, a pine forest gate and an iron spirit gate are Liu Jikun’s key focus, especially during the flood season, which is almost a must-visit every day. Songlin Gate undertakes the important function of transporting water from the South Changhe River to the north moat, while Tieling Gate is a necessary node for transporting water to inner city rivers and lakes such as Shichahai.
Liu Jikun said that in order to ensure the flow of the Nanchang River, in recent years, the Nanchang River has maintained a small flow of water release all year round, and it has not stopped even in winter. The Nanchang River flows through Zizhuyuan Park and Beijing Zoo. Every half month or 20 days, the inner lake of the two gardens has to be replenished 30,000 to 50,000 cubic meters. The Songlin Gate and the Tieling Gate are open almost all year round under non-special circumstances, and the average daily water supply of rivers and lakes in the inner city is 80,000 cubic meters.
This year's Winter Olympics , the ancient river of the Nanchang River has also become an important landscape leisure corridor around the Winter Olympic venues.
is located on Wutasi Road on the north bank of the Nanchang River, close to Capital Stadium . Last spring, the Haidian District Water Affairs Bureau and the Haidian District Urban Management Committee jointly carried out a comprehensive rectification of the Nanchanghe Head Section and Wutasi Road. The 730-meter-long river along Wutasi Road is built to further purify the pollution caused by surface runoff in the early stages of each rainfall; build stone bridges and viewing platforms, open up waterfront trails, and change the river slope protection into hierarchical steps, so that tourists can climb down from the steps and go to the riverside to "close contact" with the waterscape. The two sides of the river also added reliefs and other landscape nodes based on the scenes depicted by "Wanshoutu·Chuoying Long Section" and "Luhuanhuijing Album" to show the rich historical and cultural connotation of the Nanchang River.
At present, the western section of the South Changhe River, that is, the 3.2-kilometer-long river channel from Changhe Gate to National Library, is undergoing renovation.Wang Dongdong, head of the Engineering Section of the Haidian District Water Affairs Bureau, introduced that this renovation will widen the original Binhe Road on both sides of the western section of the Nanchang River, from the existing width of 1 meter to 1.5 meters, and two people can go hand in hand; open up the existing bottlenecks and realize "going to the end" along the riverside. According to ancient records, the two existing wharfs opposite Zizhuyuan and near Wanshou Temple will be rebuilt, striving to repair the old as before; reliefs and viewing platforms will be added along the line.
"At present, the slope protection on both sides of the river on both sides of the western section is relatively steep. In addition to the original willow trees, there are only ivy. This time the slope protection will also be transformed to facilitate the water-friendly of citizens." Wang Dongdong said that after the slope protection renovation, the two sides will also need to replant greening, mainly willow trees, matched with peach trees and shade-tolerant flowers and plants. At present, the project is preparing for construction and will be opened to the public after replanting some plants next spring. By then, the two sides of the Nanchang River will be red and green, and the beautiful scenery will be like a picture.
