Character experience

1933 10 9, Li Jijun was born in Pengzhou, Sichuan, and received a good family education since childhood. He studied in Pengzhou Middle School, Sichuan Province, and was the first president of the Student Union and the first secretary of the Youth League Branch of Pengzhou Middle School.

195 1 year, went to Chongqing as a student representative to attend the Southwest Student Congress.

1952, graduated from Li Jijun high school. Originally, he wanted to apply for geology in college, but his teachers and classmates said that his health was too much, and he was advised to "study geography instead". Finally, I applied for the geography department of Sichuan University. One year later, he was transferred to the geography department of Nanjing University as the secretary of the class league branch.

1956, after graduation, he was recommended to study in the Department of Geography of Lanzhou University, where he studied under Wang, a geographer studying in Germany.

1958, graduated from Lanzhou University, majoring in geography, and stayed on as a teacher after graduation. In the same year, China Academy of Sciences organized the first research team on the utilization of alpine ice and snow in China. He became one of the first members after graduating from master's degree and led a small team to undertake the investigation of modern glaciers in the upper reaches of Heihe River. In the same year, I went to Qilian Mountain for the first time to study ice and snow resources.

1962, studied in the geomorphology department of Peking University (to 1963).

1972 cooperated with Mr. Shi Yafeng, and it took more than a year to compile the popular science booklet "The World of Ice and Snow".

From 65438 to 0973, at the age of 40, he resumed glacier research, joined the Qinghai-Tibet expedition of China Academy of Sciences and served as the head of the glacier group, responsible for glacier investigation and research in Tibet and later Hengduan Mountain. From Aza Glacier to Ruoguo Glacier, Qiaqing Glacier and Baiyu Glacier, Li Jijun and his glacier team have investigated glaciers in mountainous areas of Tibet in recent years. From ancient glaciers to modern glaciers, from continental glaciers and marine glaciers in modern glaciers, the glacier area is 46,600 square kilometers, accounting for 83% of modern glaciers in China.

1978 resumed the professional title system and was named as an associate professor. In the same year, with the reform and opening up, Shi Yafeng and Xie took the lead in going abroad and visiting Britain, France and Switzerland. 1983 Promoted to Professor of Lanzhou University.

1984 Director of Geography Department of Lanzhou University. In the same year, at the invitation of American scholar S. Porter, he went to work in the Quaternary Research Center of Washington University for one year (-1985).

1990, China Qinghai-Tibet Plateau Research Association was established. Li Jijun served as the first executive director (1990-1994), the second vice chairman (1994-1998) and the third vice chairman (1998).

199 1 was elected as an academician of China Academy of Sciences.

1992, cooperated with the Department of Geography of Royal holloway College, University of London, UK, and sent scholars to visit each other (-1995). In the same year, he realized the urgency of western development, carried out basic research on related disciplines in advance, and put forward practical suggestions to the government.

1995, vice chairman of the Chinese Geographical Society.

1999, was hired as a professor at the School of Geographical Sciences of Nanjing Normal University.

In September, 20001year, the key laboratory of the western Ministry of Environment and Education passed the acceptance of the Ministry of Education, and Li Jijun served as the director of the academic Committee.

In 20 12, the 80th birthday was celebrated by means of "field trip and field discussion". On the top of the Yellow River Stone Forest in Jingtai, Baiyin, four generations of teachers and students tell about the geological vicissitudes and evolution history of the Yellow River.

Major achievements

achievements in scientific research

Li Jijun is engaged in glaciology, geomorphology and Quaternary research. The uplift of the Qinghai-Tibet Plateau and its impact on the environment are deeply studied, and it is pointed out that the Qinghai-Tibet Plateau experienced two leveling and three uplift in the late Cenozoic. The recent strong rise began in 3.6 million years, and went through the Qinghai-Tibet Movement (3.6 ~/kloc-0.7 million years), the Huang Kun Movement (/kloc-0.2 ~ 0.6 million years) and the * * Peace Movement (0.66 years). It is pointed out that the multi-stage terraces in the upper reaches of the Yellow River are periodic reflections of plateau uplift, which were respectively formed 1.7, 1.5, 1.2, 0.6 and 0. 1.5 million years ago. It is pointed out for the first time that there are a large number of hot and humid geomorphological relics and some cold debris flow geomorphological systems in Lushan Mountain, which replace the explanation of glacier origin.

Li Jijun's main academic achievements can be summarized as follows:

① The rising stage, rising range and rising form of the Qinghai-Tibet Plateau are put forward: it is the first time at home and abroad to systematically and comprehensively put forward the rising stage, rising range and rising form of the Qinghai-Tibet Plateau. 1979 points out that the whole fault block of the plateau accelerated to rise by 3500-4000m in Quaternary, which had great influence in academic circles. Later, it was pointed out that the Qinghai-Tibet Plateau had strong movements 3.6 million years ago, 240 million years ago and10.6 million years ago. It is believed that about 2.4 million years ago, the altitude of the plateau exceeded 2,000 m, which led to the modern East Asian monsoon, and a large amount of loess accumulated in the middle reaches of the Yellow River, forming the famous Loess Plateau. It is pointed out that the Yellow River is the product of the uplift of the Qinghai-Tibet Plateau. With the intermittent rise of the plateau, the Yellow River produces traceable erosion and corresponding undercutting; It is pointed out that the Yellow River and Jinsha River in Lanzhou were connected after 6.5438+0.6 million years ago, and the multi-stage terraces formed in the upper reaches of the Yellow River 654.38+0.6, 654.38+0.5, 654.38+0.2, 0.6 and 0.654.38+0.5 million years ago reflected the stage of plateau uplift. The ages of the above sections of the Yellow River in Lanzhou have gradually changed, corresponding to the specific terraces in Lanzhou. And Late Cenozoic Uplift and Environmental Change of the Qinghai-Tibet Plateau edited by Shi Yafeng.

(2) Systematic research on modern and Quaternary glaciers in Tibet: especially, I have new opinions on monsoon marine glaciers, and edited Tibet Glacier and Hengduan Mountain Glacier. It is pointed out for the first time that there are a lot of hot and humid landforms and some cold debris flow landforms in Lushan Mountain, which has replaced the explanation of the origin of glaciers and generally clarified the ancient glacier dispute that has puzzled geologists in China for half a century.

③ Study the loess stratum in Lanzhou area, and link the loess with the uplift of Qinghai-Tibet Plateau: It is pointed out that Lanzhou loess is much younger than Luochuan loess, and its deposition rate is 4-5 times that of Luochuan loess. For the first time, the loess record of Linxia North Plateau was compared with the oxygen isotope curve of Antarctic ice core, and the environmental changes compared with the ice core record for 6.5438+0.5 million years were reconstructed. The concept of "monsoon triangle" is put forward, and it is clear that there are two modes of quaternary environmental change in northern China: monsoon mode and westerly mode, which has played an important role in promoting the study of quaternary environmental change in northern China.

Li Jijun put forward many insightful opinions of great academic significance. For example, in the 1980s, he proposed that the monsoon region and westerly belt in western China in the late Pleistocene had different environmental evolution models, the former was a combination of warm, wet, cold and dry, and the latter was a combination of warm, dry and cold and wet; 1993 put forward the viewpoint of pacemaker and initial area of Qinghai-Tibet plateau, and thought that Qinghai-Tibet plateau might play a very important role in global change. He developed and perfected the theory of "Asian pole" put forward by De Jinri and Terol in his early years. He believes that the Asian dry pole is located in Qiangtang Plateau, surrounded by the Asian monsoon coupling system, and the soil and vegetation are concentrically distributed around this dry and cold core. He also began to pay attention to the influence of the east coast of Asia, especially the South China Sea, on the origin of China monsoon, and so on.

Li Jijun visited Lushan Mountain for three times. Through on-the-spot investigation, he gradually became suspicious of the ancient glaciers in Lushan Mountain advocated by Li Siguang. Li Siguang is the big dipper of Mount Tai in the geological field of China, and it undoubtedly takes great theoretical courage to dare to doubt his assertion. However, Li Jijun participated in the great debate on ancient glaciers in eastern China with a persistent energy. He made full use of the research results of marine glaciers in Hengduan Mountain area at the same latitude as Lushan Mountain, and formed his own opinions, which were widely recognized by the geographical circles. Since then, Li Jijun, in cooperation with Shi Yafeng and Cui Zhijiu, edited and published the monograph Quaternary Glaciers and Environmental Problems in Eastern China. After the publication of this book, it has had a great influence in academic circles, and the dispute over ancient glaciers that has plagued China's geosciences for half a century has been generally clarified.

As of 20 15, Li Jijun won the first prize and the second prize of scientific and technological progress of the Ministry of Education; Grand Prize and Second Prize of Basic Research Award of China Academy of Sciences; National natural science first prize 1 item, 3 second prizes.

From 1973 to 1980, after eight years' efforts, Li Jijun and other collaborators have written two monographs, Tibet Glacier and Hengduan Mountain Glacier, which comprehensively expounded the distribution, nature and changes of modern glaciers on the Qinghai-Tibet Plateau and Hengduan Mountain and their relationship with climate and atmospheric circulation. Up to 20 15, more than 200 academic papers have been published.

From 65438 to 0978, China Glacier Delegation, together with Shi Yafeng and Xie, visited Europe and attended the International Glacier Conference held in Switzerland, which greatly opened Li Jijun's scientific vision. He had academic exchanges with foreign experts such as British geomorphologist Derbyshire. 1980 invited British geomorphologist Derbyshire to visit Lanzhou University, held a three-month national seminar on glacier sedimentology in colleges and universities, and organized a field trip to Lushan Mountain and the source of Urumqi River.

personnel training

Li Jijun has always attached importance to field investigation, emphasizing that first-hand field data is an important foundation of geoscience work. He is not an academic, he values the all-round development of students. Especially with the spread of social corruption and the intensification of infiltration into the intellectual class, he attached great importance to the shaping of talent quality. He used his whole life to interpret "Reading thousands of books and Walking Wan Li Road." He has rich field experience, keen observation, super judgment and discrimination, and vivid narration, which is very attractive to students. Li Jijun's study of geography is not limited to geography, but combines geography with geology, atmospheric science, biology and other disciplines. He asked the students in the same way. This is the actual need of studying the uplift of the Qinghai-Tibet Plateau and environmental changes, and it is also the theoretical accomplishment of scientists.

Li Jijun pointed out that telling the truth can be summed up as a problem, that is, the problem of being a man. Learning and doing things at work require truth, pursue truth and strive for truth, otherwise, the cart before the horse will lead to academic corruption. We should advocate seeking truth from facts, honesty, truth, goodness and beauty, especially for scholars. Those who do not stress honesty, pursue fame and fortune, and go astray in the academic team will eventually fail.

Li Jijun attaches great importance to the organic combination of scientific research and high-level personnel training. Under his leadership, the Geography Department of Lanzhou University became a well-known department in China, and 200 1 Physical Geography won the first place in the national key discipline. He presided over the project "Based on the West, Reform and Innovation, Building a First-class National Scientific Geographical Base" and won the first prize of the Fifth National Teaching Achievement in 2005.

By the end of 20 15, Li Jijun had been engaged in education for more than 50 years, and successfully trained more than master's and doctoral students 100. Many of them became backbones and discipline leaders of key universities and scientific research institutions in China, and three of them were elected academicians of China Academy of Sciences (Qin Dahe, Yao Tandong and Chen Fahu). Regardless of his weak health, he has taken students for field practice many times. Under his influence, many students devoted themselves to the research fields of environmental protection, environmental change and natural environmental processes. Teachers and students Li Jijun, Qin Dahe, Xiao Cunde and Dai Yong broke into the three poles of the earth, which has long been a beautiful talk that Landa people are proud of.

Li Jijun's success comes down to "persistent pursuit of ideals and scientific truth". This spirit not only realized his personal career ideal, but also influenced a school, a discipline and even many scholars with academic dreams. The national innovation group of "Environmental Change in Western China" led by Chen Fahu was awarded as excellent by the National Natural Science Foundation twice. Sun Donghuai, Pan Baotian and Zhao Yan successively won the National Science Fund for Outstanding Young Scholars, and Wang Naiang won the National Teacher Award in 2007. Zhao Yan won the Eighth China Young Female Scientist Award, An won the Sixth China Young Scientist Award for Quaternary Research and the Eighth National Youth Geography Science and Technology Award, Gou Xiaohua won the Ninth National Youth Geography Science and Technology Award and the Seventh Qinghai-Tibet Plateau Youth Science and Technology Award, and Meng Xingmin, Ding presided over three national support programs.
