Yellow River , flowing endlessly and extending thousands of miles. It has been the cradle of the Chinese nation since ancient times and a symbol of the Chinese national spirit. In the "Ji"-shaped area where the Yellow River enters the middle reaches from the upper reaches, there are Eurasian grasslands closely connected to Yinshan. This place is vast and endless, but it was once one of the most concentrated and most harmful areas in the country with desertified and desertified land.

General Secretary Xi Jinping pointed out that we must adhere to the comprehensive management, systematic management, and source management of mountains, rivers, forests, fields, lakes and grasslands, strengthen coordination and cooperation, and coordinate the promotion of the high-quality development of the Yellow River Basin . As an important ecological security barrier in northern my country, Inner Mongolia has important responsibilities and missions for maintaining the security and stability of the motherland's northern border and promoting the high-quality development of the Yellow River Basin.
Now, the ecological environment along the Yellow River has undergone earth-shaking changes, and the beautiful grasslands continue to shine with new colors.
After the governance along the Yellow River is stable,
is located along the Yellow River. There is such a team dedicated to grassland ecological protection and restoration. This is a group of young scientific and technological workers, with an average age of only 35 years old. They have ideals and beliefs, and look at the harsh natural environment along the Yellow River, and feel a heavy responsibility on their shoulders when they look at the harsh natural environment. They are the team of the National Field Science Observation and Research Station of Grassland Ecological Hydrology , the northern foothills of Yinshan Mountain in Inner Mongolia, and won the 10th " Mother River Award " Green Team Award in 2021.

"Ecological governance is not a fantasy sitting in the office. We must go deep into the front line to understand the current situation of the ecological environment. Only through systematic observation, thinking, and practice can we lay a solid foundation for scientific governance." It is precisely with this belief that the team has been rooted along the Yellow River, and has been rooted in the original aspiration and sticking to their posts for 10 years.

In order to obtain first-hand long sequence measurement data, realize environmental changes along the Yellow River and systematic research on the laws of wind and sand migration, the team has been stationed in the deserted Liuguaizi Shatou for a long time. With full of passion, their newborn calf is not afraid of tigers. In the desert where "yellow sand covers the sky, birds have no trees", the scorching heat is unbearable in the scorching sun at 40 degrees in summer, and the cold wind is biting in the sand at minus 20 degrees in winter. Deep in the desert, cars could not move, and they carried the instruments to walk at least 3 kilometers to the test site every day. On weekdays, I carry water, steamed buns and pickled vegetables when I go out to work. It is a luxury to eat a bucket of instant noodles in the whistling wind and sand.

They use weather forecast as reference materials, wind as order, and sand as the signal. They hold the recorder tightly in one hand, while observing the sand collector, and stick to the observation point motionlessly. Sometimes at night, I still have to stay in the sand nest and wait for the strong wind to come.
However, the difficulties in front of us are temporary, and what is even more difficult is the difficulty in the progress of scientific research and the lack of satisfactory results after many trials. With the support, trust and encouragement of the unit, they have the spirit of "yellow sand wears golden armor for hundreds of battles, and will never return until Loulan is destroyed". After field practice, visits and research, and the literature review, the team has obtained more than 600,000 first-hand basic data, and has initially figured out the wind and sand flow structure, sand dune shape, sand dune migration laws, land use and other aspects along the Ulanbuhe Desert section of the Yellow River, providing a solid foundation for scientific answers to the amount of sand accumulated in the yellow wind entering the area.

In order to be able to ecological security screen in the northern border of the motherland The team contributed a little more effort to the construction of obstacles. The team expanded the main battlefield of scientific research to the top ten Kongdu areas of the Kubuqi Desert in . This area is a typical Feng Shui compound erosion area. In winter and spring, the wind and sand are frequent, and quicksand enters the Kongdui Riverbed ditches. In summer and autumn, every time heavy rain occurs, the Kongdui flood will carry a large amount of silt, which not only seriously silts the Inner Mongolia section of the Yellow River, but also seriously restricts the economic and social development of the surrounding areas and threatens the lives and property of the people. Over the past few years, the team has not been afraid of difficulties, adhered to a scientific attitude and persistent spirit, and worked outdoors for more than 135 days a year.
During the investigation, the team leader Guo Jianying repeatedly emphasized: " must not be separated from the masses in scientific research. Our goal is to serve the people. The difficulties encountered by the masses are the source of scientific problems. ." In this way, the team quickly understood the natural environment around the top ten Kongdui areas, and at the same time formed a deep and simple friendship with local farmers and herdsmen. It is precisely this simplicity and specialized research that the team has explained the contribution of the ten major holes of the Yellow River tributaries to changes in the main flow water and sand conditions through experimental research, which is of great significance to protecting the Yellow River, improving flood control security, improving the ecological environment, and promoting local economic and social development.

shoulders the responsibility, so that science popularization is silently
Scientific research and popularization are inseparable. Over the years, the team has been committed to the development of popular science work and organized various forms of popular science activities, which have also continuously attracted young people to participate in the ecological protection and restoration of the Yellow River Basin.
021 On December 16, 2021, the Grassland Soil and Water Conservation Ecological Technology Experiment Base of the Pastoral Water Science Institute of the Ministry of Water Resources was selected as the fifth batch of "National Soil and Water Conservation Popularization Education Base" of the Chinese Society of Soil and Water Conservation. The base is an important scientific research and popular science demonstration platform for the Desert Grassland Ecological Hydrology Field Scientific Observation and Research Station in the northern foothills and Yinshan Mountains, Inner Mongolia. The National Soil and Water Conservation Popular Science Education Base is built on the basis of the National Soil and Water Conservation Science and Technology Demonstration Park. It is an open place to the society and the public, able to publicize and popularize scientific knowledge of soil and water conservation, and carry out popular science experience activities for soil and water conservation. It is an important platform for providing soil and water conservation science services for the public and an important carrier for soil and water conservation popular science work. 022 National Science and Technology Activity Week , the team held the "Walking into Science and Technology You and I Walk with You" theme, and the team held the "Wind Science Observation and Research Station Cloud Study Activities". The team experts gave popular science explanations on "Practical Guidance on Comprehensive Survey of Grasslands", and gave detailed explanations on grassland plant classification, vegetation soil sampling methods, ecological hydrological surveys, carbon cycle observations, and nearly 100 people participated in the study and study activities. "Cloud Study Activities" popularized field test technology methods to the society and demonstrated advanced scientific devices, which played a positive role in widely disseminating scientific knowledge, scientific ideas, scientific methods and scientific spirit, and improving scientific literacy. In October 2021, with the approval of the Ministry of Science and Technology, the "Ecological Hydrology and Field Scientific Observation and Research Station of Desert Grassland Northern Footstep Yinshan Mountain in Inner Mongolia" was officially upgraded to the "National Field Scientific Observation and Research Station of Grassland Ecological Hydrology in the Northern Footstep Yinshan Mountain in Inner Mongolia", achieving a zero breakthrough in the construction of a national field science observation platform. The establishment of the
national station will strongly support the development of ecological and hydrological sciences in the grassland area of my country, and is of great significance to strengthening water source conservation, hydrological regulation, sand and dust prevention, biodiversity conservation, system regulation of water, soil, grass and livestock, and even regional ecological civilization construction in grassland areas.
In the future, the team will continue to be full of ideals on the road to Huangzhu research, firmly believe that
is not afraid of hardships, forge ahead
down-to-earth and selfless dedication
Use the pen of struggle to write the song of ecological civilization construction in the Yellow River Basin
Let the beautiful Yellow River continue to meander through the grassland!
