Except for more: Graduated from the Graduate School of the Chinese Academy of Sciences in March 2003, received a doctorate in science, and is the No. 1 Meteorological Bureau of the Tibet Autonomous Region working in Tibet. A Ph.D. Currently working at the Environmental Science Research Institute of Plateau Atmosphere, Meteorological Bureau of Tibet Autonomous Region. In addition to being in charge of the National Natural Science Foundation of China and key projects of the Tibet Autonomous Region, he has published 4 monographs and more than 80 papers. Won 2 first prizes, 1 second prize, and 3 third prizes in the Tibet Autonomous Region Science and Technology Awards.
” Seeing Chu Duo, he still had a look of fatigue on his face. As the deputy director of the Institute of Environmental Science of the Plateau Atmosphere of the Meteorological Bureau of the Tibet Autonomous Region, he had just experienced a long trip: 12 days, more than 5,800 kilometers, and an average altitude of more than 4,500 meters along the way.
Through aerial observation and comparing it with information collected by satellite remote sensing, he can determine changes in snow cover, grassland, etc. The sun was shining brightly outside the window, and a few clusters of clouds were floating in the blue sky. I have watched this sky for decades more. The sky that people regard as a scenery, in Zhu Duo’s eyes, is related to the lives of countless people on the plateau.

“I want to do scientific research, but my foundation is too weak”
Except most of them were born in Bailang County, Shigatse, Tibet Autonomous Region. At the age of 17, he was admitted to the then Nanjing Institute of Meteorology from Gyantse Middle School, majoring in atmospheric detection. He was the only student in the county who went to university at that time. When I was studying in Nanjing, I only returned home once at most, just to save travel expenses.
After graduation, Jamaicans Escort worked at the Tibet Autonomous Region Meteorological Bureau Meteorological Station several times . At that time, the daily task was to receive satellite cloud images, process the images, and provide them to the forecasting department. “At that time, I felt quite satisfied that I could apply what I had learned.” Chu Duo recalled.
In the early 1990s, Tibet developed aFor the comprehensive development and construction of its mainstream Nianchu River and Lhasa River basins, the Meteorological Bureau of the Tibet Autonomous Region and the Institute of Remote Sensing Applications of the Chinese Academy of Sciences jointly collaborated on a project to use satellite remote sensing technology to analyze the results of development and construction.
In addition to spending most of the day with the teachers of the Chinese Academy of Sciences. He and experts from the Institute of Remote Sensing conducted multiple field surveys in 18 counties and cities in the central basin. The living and road conditions are very difficult. Following the experts, they went into the valleys and forests and completed a survey of more than 60,000 square kilometers.
On the plateau in summer, the weather is not very hot, but the sun is blazing, and sunburn is common. In the teachers, he felt his lack of knowledge. The teacher can clearly understand the remote sensing pictures that I can’t understand at a glance; the technical principles that I don’t understand can be explained in a few or five sentences by the teacher… In addition to wanting to continue learning, “I want to do scientific research, but I’m not too good at it.” Thin.”
In 1997, a phone call from Nyima Tashi, then president of the Academy of Agricultural Sciences of the Tibet Autonomous Region, made Zeduo’s dream come true: “Zeduo, we now want to send a batch Are you interested in having comrades from Tibet go to Beijing for dinner and training? ”
“Of course!” Zhu Duo responded immediately. In 1998, except Duo successfully passed the Institute of Geography and Resources of the Chinese Academy of Sciences, he studied for master’s and doctoral degrees continuously for more than 5 years, and finally obtained a doctorate.

“Scientific research is a lasting accumulationJamaica Sugar Daddy’s journey, 15 years is really not a long time”
In 2003, after graduation, he returned to Lhasa and became a Westerner The first doctorate from the Meteorological Bureau of the Tibetan Autonomous Region to complete the work of returning to Tibet. Returning to Lhasa, he continued the research he started when he was a doctoral student – using remote sensing methods to analyze the land use situation in Lhasa and surrounding areas.
I became associated with this issue because of a research project started in the early 1990s. In that assessment, in addition to accumulating scientific research data and field assessment experience,Calendar. Every year during the assessment, he would describe the annual new land use types in the One River and Two Rivers area on aerial photos. After completing the assessment and returning indoors, he still needs to record the new types on the photos into the computer one by one. “I’m so tired that my back aches and my legs hurt,” Chuduo said.
During his Ph.D. studies and work, he continued to update, supplement, and improve the data. By the time the results were officially published, a full 15 years had passed since the beginning. “Scientific research is a long-term accumulation process, and 15 years is actually not a long time.” He said.
At an altitude of 4,200 meters, Lhasa is the dominant city. Looking around, you can see the vast grassland and the snow-capped mountains in the distance. Due to the high altitude, the grass here is not dense, and most of the right and wrong can be traced at the fingertips.
Grassland is the rarest land type and ecosystem in Tibet. “They are the main body in protecting the ecological security of the Qinghai-Tibet Plateau.” Zhu Duo said, “Grassland degradation has become an important obstacle to the sustainable development of the Qinghai-Tibet Plateau ecology. Regarding the situation of grassland degradation, there are large differences between different studies.”
How to correctly observe grassland changes? In addition to focusing more on the sky – he hopes to observe the changes in the grassland of the Qinghai-Tibet Plateau through satellite remote sensing. But it is difficult to make a correct estimate of surface grassland just by relying on the “overlook” of remote sensing. “JM Escorts Tibet has complex natural conditions and diverse ecological types. The previous budget method cannot be used directly and needs to be ‘started from scratch’.” Except say more.
In addition to establishing aerial observation stations in multiple places, combined with on-site observations and remote sensing observations, we will re-modify the existing budget methods. Through point tests and various parameter indicators, a calculation formula for grassland conditions that is suitable for the plateau reality was finally established. This formula is highly accurate and has had widespread influence at home and abroad.
In addition, it also uses linked remote sensing and aerial observation to expand the scope of remote sensing technology. “For example, vegetation coverage, surface temperature, soil moisture, etc., a remote sensing monitoring model has also been established.” Zhu Duo said.
“We need to conduct more and more in-depth research and propose disaster prevention and reduction strategies”
The Qinghai-Tibet Plateau is the roof of the world and the water tower of Asia , is an important ecological security barrier in my country. Under the influence of global climate warming, the cryosphere of the Qinghai-Tibet Plateau is undergoing historical changes. In addition, many are interested in this: how to conduct in-depth research on cryosphere changes and the impact of global climate change on them.
2012, TibetThe Meteorological Bureau of the Autonomous Region has formulated a plan and hopes to establish a long-term snow cover data set on the Qinghai-Tibet Plateau for climate change prediction and provide data support for the third Qinghai-Tibet Plateau Atmospheric Science Experiment. “We have carried out too little research in related fields, but this is one of the duties of the meteorological department, and we are bound to do so,” Zhu Duo said.
Changes in personal academic interests and the needs of the work unit jointly prompted Du Duo to start changing his research interests. Focusing on the glaciers and snow outside the grassland, he began to research the cryosphere of the Qinghai-Tibet Plateau.
You can see the clouds of snowfall from a distance, but you need to go to the scene to know what the snow looks like and how deep the snow is. In order to conduct better research, he set up observation equipment in many places in Tibet to collect information such as snow depth. Through world-wide observation and comparison, in addition to improving existing research methods, we hope to make more contributions to meteorological research.
I jumped out of the car, opened the door, and walked into the observation area. There was a full 60 centimeters of snow. When I stepped on it, the snow almost reached my knees. Walking to the instrument, he skillfully opened the device, recorded it, and kept the sample.
This is the weather observation station in Nyalam County, Shigatse City, and is also the place where many JM Escorts. “We have built automatic ground-based snow observation stations here and in other key heavy snowfall areas in the region. No matter how powerful the satellites are, they can only reflect the surface conditions of the snow, and many key factors such as snow depth have to rely on ground-based inaccuracies. Ya test. “Zhuduo said.
This is a scene when Zhu Duo went out for an inspection in February this year. This 5,800-kilometer investigation trip was to observe and understand the impact of this year’s heavy snowfall on the local area.
When conducting research on ice and snow, in addition to the disaster scenes that year were always in his mind, he felt that the burden of research on ice and snow disasters was a little heavier.
Only with the information in hand can we make decisions and take measures to achieve the goals of disaster prevention and reduction and saving lives and property.”
From satellite remote sensing to aerial observation, from mountains to grasslands. The snow, in addition to tracking the wind and clouds in the sky, is also stepping on the land of the Qinghai-Tibet Plateau step by step. After decades of scientific research, he has also observed some changes in the scene between heaven and earth——
“The global climate is getting hotter, human activities in the plain ice and snow belt are increasing, and the problems caused by cryosphere disasters are also increasing. “We need to conduct more and more in-depth research and propose disaster prevention and mitigation strategies, especially for cryosphere disasters,” Duo said. ”
Seek truth and apply it to make scientific research stable and far-reaching
From remote sensing data to budgeting methods, from grassland biomass to detecting snow disasters, Zhuduo’s scientific research is not only about “seeking truth”, but also about “application”. The love for scientific research has far-reaching significance for the development of the city.
Pursuing truth is the foundation of greatnessJamaicans SugardaddyThe root system can support towering trees. It is on the basis of decades of continuous data accumulation that a set of remote sensing observation methods suitable for Tibet can be optimized. , provide scientific support for the protection of the Qinghai-Tibet Plateau, seek truth and practicality, and make scientific research progress steadily. In addition to several turns in the road of multi-research, they are all related to the actual needs of Tibet’s development and are issues that need to be solved urgently in regional development. Anchor the urgent issues of social development and promote the continuous improvement of scientific research and exploration. Exploring the truth and serving the plateau are integrated in the intersection of two forces. Inspired by this, he has been on the road to observe plateau scenery for more than 20 years, enjoying it and persevering…
