Yellow River News reporter Pu Fei
At 3 o'clock in the afternoon yesterday, after lunch in Lanzhou City, this reporter interviewed the Lanzhou Hydrological Station and the Yellow River River Management Station by the Yellow River in the city.
Lanzhou Hydrological Station uses two new hydrological monitoring instruments, lead fish and radar velocimeter. In June last year, the river management station transformed the abandoned Lantie pumping station into a water-friendly leisure place for citizens on the Baili Yellow River style line in Lanzhou City, and on August 21, General Secretary Xi Jinping came here and put forward the idea that the Yellow River should be well protected and treated.
At 5:00 p.m., we headed up the Yellow River toward Qinghai. Just after crossing gansu, Wu Xing, deputy director of the office of the hydrological station in the upper reaches of the Yellow River, said that not far ahead is Minhe County, Qinghai, where there is a hydrological station, which is not only a national basic hydrological station, but also a key flood control unit identified by the National Flood Control and Drought Control General Command, and an automatic water quality monitoring station that has been explored since 2017. Located in the remote deep mountains, the conditions were harsh but they did a great job. I said, "I'm not going to Xining tonight." ”
In the twilight, the car drove off the highway and drove over a small bridge over the Huangshui River, and on a high ground near the river, there was a small courtyard and a basketball court. Our car was parked on this basketball court. The left hand of the basketball court, more than a person tall, is a small two-story building with a beige exterior painted. Wu Xing went upstairs for about ten minutes, and a middle-aged man wearing a blue jacket and a thin face came downstairs to us.
"This is the stationmaster of the Minhe Hydrological Station." Wu Xing said.
"Your last name?" I shook hands with him and asked.
"Yu Lianqing. Dry hook in, connected in, qinghai green. After he explained, he invited him to sit upstairs, and I said to sit in the courtyard and watch the Huangshui River and talk.
"How old is The webmaster this year?"
"Old, 55 years old."
"You're two years younger than me!" We are not old. ”
"Yeah, I'm in good health!"
"How many years have you been at the Hydrological Station?"
"Coming and short time. It only came in 2017. I used to work at the Tang Naihai Hydrological Station, and I worked for a little more than 19 years. ”
"Tang Naihai is on the side of the Sanjiangyuan and is one of the highest hydrological stations at the highest altitude. In a small village, 20 kilometers from the county seat. Wu Xing added.
"After I left, the small village was also relocated, leaving the hydrological station, which was very lonely and the traffic was not good." Yu Lianqing stressed, "However, it is a very important hydrological station, and the current water quantity number of the Yellow River, just like the 4 flood peaks in the Yellow River Basin that have been released this year, are based on the hydrological data measured by Tang Naihai." There is natural water, no human activity, and no power station. ”
"Did your lover and children go with you when you were there?"
"Nothing. I'm alone. She works as an accountant in a business at home. ”
"No one takes care of your life, it's hard."
"Get used to it."
"Where is your home?"
"It's here. People and peace. ”
"Then how did you get to Tang Naihai?"
"Organizationally arranged."
"How old was that year?"
"33 years old. I started working early, at the age of 16, to take over my father's job. ”
Yu Lianqing said that his father was also an old hydrologist who had worked at the hydrological station all his life, first at a hydrological station in Gander, Sanjiangyuan District, which no longer existed, and was later transferred back to the Xiangtang Hydrological Station as the station manager. After his father retired, he graduated from junior high school in 1981 and took over, working at the Xiangtang Hydrological Station, then being transferred to the Hydrological Station in Jungong Township, Sanjiangyuan District, for 1 year, and then to the Mado Hydrological Station for 3 years. Although these three hydrological stations are in the source area, they are not in one direction and are far apart, more than 200 kilometers.
There are currently 11 hydrological stations in Sanjiangyuan District, and Yu Lianqing alone has worked on 3. After he finished his work in Mado, he attended the staff school for 2 years, then worked in Xiangtang for 7 years, and then was transferred back to Tang Naihai in the source area as a station manager, and worked for 20 years. Now he has been dry hydrology for 39 years, and it will be 40 years soon.
Tang Naihai Hydrological Station is a very old hydrological station, which was established in 1939. There is also one of the earliest hydrological stations established in the upper reaches of the Yellow River, which is the Lanzhou Hydrological Station, which was built earlier in 1934. The others were built after the founding of New China.
He said that the work of the hydrological station, year after year, day after day, is to measure the flow, sand content, rainfall, etc., the work is not complicated, the key is to worry, careful, but also not afraid to eat, endure loneliness, withstand repetition. Repeating a thing a hundred times is nothing remarkable; repeating it a thousand times is boring and tedious; repeating it 10,000 times is remarkable. And Yu Lianqing has been repeating it for almost 40 years, more than fifteen thousand times! Hydrological stations are generally still remote and have few personnel, that is, six or seven people. In the past, there was no cultural life, unlike the Internet now, and no matter how remote it was, it was connected to the big world.
While we were talking, two young men moved two chairs and sat down next to us. Yu Lianqing introduced: "Both of them are college students who were just assigned last year, and this girl is still a graduate student. ”
The girl's name is Huang He, 25 years old, undergraduate and graduate students are Ningxia University hydrology and water resources engineering major, home is in Yinchuan City. The boy's name is Liu Jiawei, even younger, only 23 years old, graduated from Shangqiu Institute of Technology with a major in accounting, and grew up in the provincial capital city of Zhengzhou.
I asked, from the capital city to a remote ravine, is it customary? They said it was ok, better than expected. It seems that they are all ready to suffer.
"To Minhe, what do your parents think?" Are they willing? ”
"They're all pretty supportive." Both young men said so.
"You've been working here for more than a year, have they come to see you?"
"Nothing. Nor did we offer to let them come. Our parents were very reassured about us. The two young men laughed.
It is reported that there are three other people at the Minhe Hydrological Station. A female comrade, more than 30 years old, named Gao Mengyao, graduated from the East China Water Institute, is a citizen and a local, and her father was also from the Xiangtang Hydrological Station. The other is Wei Tao, 50 years old this year, who is also the second generation of hydrology. There is also a man named Xue Jindai, who is in his 40s. Two young people who have just started working can get more than 4,000 yuan. Those who work at the hydrological stations in the source area have a subsidy of more than 1,000 yuan per month in remote areas. After the flood season, they can usually enjoy more than two months of vacation, and they can return to the city to spend time with their parents.
Pointing to the rushing Huangshui River around me, I said how much sand is there today? "0.5 kg." Two young men answered. Yu Lianqing said that usually there are about ten kilograms per cubic meter, but before he came here, at the highest time, there were more than 300 kilograms per cubic meter. In the south and the interior, at this time it is the season when the forests and grasses are flourishing, it is almost impossible to see the land, and here except for some trees in the river valley, the mountains near and far are almost like some grass buds just emerging in the early spring in the interior. Even so, Yu Lianqing said, this is the grass seed sown over the years, greening, much better, reducing a lot of soil erosion, so the sediment content in the river has dropped significantly.
Yu Lianqing said that in recent years, they have also been on the intelligent monitoring and reporting system, and the workload has been reduced a lot, and they used to rely entirely on manual water intake for testing. Now although manual measurements are still necessary every day, it is mainly to compare with artificial intelligence systems, and once stabilized, it is basically possible to use manual measurements. At nearly 9 p.m., when we went to dinner, we invited two young people to go with us, and they reported the day's measurement data before coming.
