Mountains and rivers depend on each other, blue and green are intertwined. In the northeast of the capital, surrounded by mountains, lies the Miyun Reservoir, known as the "Pearl of Yanshan".
In August 2020, on the occasion of the 60th anniversary of the completion of the Miyun Reservoir, the general secretary of the ** sent a letter to the villagers who built and guarded the Miyun Reservoir, asking everyone to protect the priceless treasure.
Over the past three years, the reservoir managers and surrounding residents have kept in mind the general secretary's advice, guarded and made good use of the Miyun Reservoir, unswervingly walked on the road of "ecological priority and green development" to preserve water and enrich the people, and made new contributions to the construction of a beautiful Beijing.

The number of birds flying in has increased by 45 in three years.
On August 30, 2020, the general secretary pointed out in his reply to the villagers: "The Miyun Reservoir was built for flood control and flood control, and now it has become a priceless treasure as an important source of surface drinking water and a strategic reserve base for water resources in Beijing. ”
This sentence impressed Wang Guoxue, deputy director of the Reservoir Belt Management Office of the Miyun Reservoir Management Office. He has been working in Miyun Reservoir for 22 years, and he has witnessed the great changes in the reservoir: there is more water, the water surface is opener, the trees around the reservoir are taller, the environment is better, and there are more birds than before!
As the "big water tank" of the people of the capital, the Miyun Reservoir has supplied more than 41 billion cubic meters of water to Beijing-Tianjin-Hebei since its establishment, of which nearly 30 billion cubic meters have been supplied to Beijing. At the end of 2014, the middle route of the South-to-North Water Diversion Project was opened to water. After the "South Water" entered Beijing, the Miyun Reservoir is no longer the "main force" of water supply in the urban area, but it is still an important source of surface drinking water in Beijing, and has transformed into a strategic reserve base for water resources in the capital. With the support of "South Water", the water storage capacity of Miyun Reservoir has increased steadily in recent years, reaching a maximum of 357.9 billion cubic meters, the highest record since the establishment of the reservoir, and continue to stabilize the operation of large reserves of about 3 billion cubic meters.
In April 2021, the Miyun Reservoir began to replenish water to the downstream Chaobai River. This water replenishment, which lasted for one year and four months, was the largest water replenishment in the Chaobai River basin in Beijing since the beginning of the new century, and the water system in the Chaobai River basin was connected, and the entire river in Beijing was opened to water.
The water surface is more open, and the ecological environment of the reservoir is also improved. Today, the water quality of Miyun Reservoir has been maintained at the second-class standard of surface drinking water all year round, and the number of bird species recorded in the reservoir area has increased from 190 before 2020 to 235 in 2023, the number of mammal species has increased from 10 to 13, more than 400 species of plants, and more than 110 species of insects, and the biodiversity has continued to increase. "You see the gray-headed wheat pheasant, hoopoe and the flock of peacebirds, the starling bird flock are all here, the water is good, the birds are coming, this reservoir is really priceless! Wang Guoxue, who was a member of the reservoir's bird-watching team, is particularly excited about the changes in the reservoir area in recent years.
5.60,000 acres of water conservation forest to eliminate pesticides.
Over the years, the Miyun Reservoir Management Office has adhered to the "departmental linkage, urban coordination, and Beijing-Hebei cooperation", thoroughly implemented the "five water conservation" requirements of upstream water conservation, forest protection and water conservation, reservoir area water conservation, water conservation according to law, and policy water conservation, and promoted scientific and technological water conservation, water conservation for the whole people, and the water ecological situation has continued to maintain a healthy level, and the water source protection work has achieved remarkable results.
In his reply, the general secretary exhorted us to make persistent efforts, do good work, continue to protect the Miyun Reservoir, and make new contributions to the construction of a beautiful Beijing. This makes the guardians of the Miyun Reservoir more determined to protect the water. "In 2021, the Miyun Reservoir set up a water environment management department and a reservoir area management office to be responsible for the management and control of the water ecological space of the reservoir. Huang Nan, chief of the water environment management section of the Miyun Reservoir Management Office, told reporters that there will be special personnel to inspect the environment of the reservoir area every day, and once illegal construction, illegal discharge of sewage, littering and other water violations are found, they will immediately deal with or notify the law enforcement department.
There are still 5 in the reservoir area60,000 acres of water conservation forest is of great significance to water conservation and water purification. Liu Lei, deputy director of the Water Ecology Institute of the Miyun Reservoir Management Office, said that in recent years, the pest control of conservation forests has eliminated the traditional chemical methods, and the use of natural enemies to kill and solve ecological problems in an ecological way. The Miyun Reservoir, which operates with large reserves, has also restored and reconstructed more than 450 acres of wetlands in combination with the dynamic characteristics of inundation areas at different water levels, and created a demonstration sample area of bird habitat at the mouth of the Chaohe River in the upper reaches of the reservoir, and planted 16 kinds of aquatic plants such as shallots and gourds to purify water quality.
The environment is better, and the passenger flow is more".
In his reply, the general secretary said emotionally: "I am very happy to learn that you have given full play to the advantages of good mountains and rivers, and your days have become more and more prosperous. "Focusing on the clear water of the Miyun Reservoir, Beijing has found a sustainable development path of "water conservation can enrich the people, and enriching the people can promote water conservation". Along this road of water conservation and enrichment of the people, "lucid waters and lush mountains" are being transformed into "gold and silver mountains" in a sound and impressive manner, benefiting the people in the reservoir area.
There is a famous "fish street" in Beijing on the south line of the reservoir in Xiwengzhuang Town, and there are dozens of fish banquet restaurants along the way, and each family has its own specialty. Every year in late September, the King of Fish Food and Culture Festival is held here, and the parking lot is filled with many diners.
Zhu Xianghong, 57, was one of the first operators on the street. Before opening the restaurant, the cages she put in the reservoir could produce tens of thousands of catties of fish every year. Later, Miyun Reservoir canceled cage fish farming, and Zhu Xianghong opened this restaurant under the guidance of the policy. "The water quality is better, the quality of the fish is better, the environment is better, the passenger flow is more, and the holidays are full almost every day! Zhu Xianghong smiled from ear to ear.
Miyun's acacia honey is famous all over the country. However, in the past, when the spring flowers were in full bloom, Li Hongyi, who had been keeping beekeeping for more than 20 years, had to quickly load the beehives and run south. "With the implementation of a series of measures such as returning farmland to ban planting and closing farms, the environment around the reservoir has improved, there are more flowers, bees do not die, and the output of honey has naturally risen. Now, every spring and summer, Li Hongyi can release bees at the door of his house in a down-to-earth manner, and two or three tons of acacia nectar a year can always be ordered by customers in advance.
Zhang Jianhua used to be a fisherman in the reservoir area, but now he is a water conservation grid worker, responsible for taking care of the purse seine nets in the reservoir area and inspecting the environment of the reservoir area, with a monthly subsidy of 1,500 yuan. Lao Zhang is very satisfied with this kind of life, and he has to inspect his pipe section at least four times a day, "Money is not the most important thing, Miyun people know a sentence, to protect Miyun Reservoir like their own eyes!" ”
