Who knows Li Siguang s information

Li Siguang (1889-1971) was a Chinese geologist and the founder of geomechanics. The word Zhonghua is a native of Huanggang, Hubei. In his early years, he joined the League and participated in the Xinhai Revolution.

He founded geomechanics in the 20s of this century and made great contributions to geological theory. He used the viewpoint of mechanics to study the phenomenon of crustal movement, regarded various tectonic traces as the result of in-situ stress activities, established the basic concept of geomechanics of "tectonic system", provided a new method for exploring geological natural phenomena, opened up a new way for the study of crustal motion laws, created a new situation in geological science, and enjoyed a high reputation in the world. His theories have made great contributions to China's oil exploration.

For example, he used geomechanics to analyze the characteristics of geological structure in eastern China, and believed that the three subsidence zones of the New China tectonic system had a broad prospect for oil searching, which theoretically denied the theory of "China's oil poverty". The successive discoveries of Daqing, Shengli, Dagang and other oil fields confirmed his scientific foresight. In terms of geological work, he emphasized that on the basis of studying the activity of geological structures, the changes of in-situ stress were observed, and the direction was pointed out for the realization of the first forecast.

In addition, as early as the early 20s, Li Siguang visited the foothills of the Taihang Mountains, the Datong Basin, the Lushan Mountains and the Huangshan Mountains in China, and successively discovered the remains of Quaternary glaciers, which overturned the erroneous conclusion of many international glaciological authorities that there are no Quaternary glaciers in China. Li Siguang has studied in Japan and the United Kingdom, and has traveled to France, Germany and Switzerland. Before 1949, he was a professor in the Department of Geology of Peking University and the director of the Institute of Geology of the ** Research Institute.

After 1949, he served as Vice President of the Chinese Academy of Sciences, Director of the Chinese Institute of Paleontology, Member of the Department of Geosciences of the Chinese Academy of Sciences, Chairman of the China Association for Science and Technology, and Minister of Geology.

Deputy to the First, Second and Third National People's Congress, Chinese People's Political Consultative Conference.

Vice Chairman of the 2nd, 3rd and 4th National Committee, member of the 9th ** Committee of the Communist Party of China.

Li Siguang (October 26, 1889 - April 29, 1971), the character Zhonggong, formerly known as Li Zhonggong, a native of Huanggang, Hubei, Mongolian, geologist, educator, family, social activist, founder of Chinese geomechanics, one of the main leaders and founders of China's modern earth science and geological work, the first batch of outstanding scientists after the founding of New China and the father who made outstanding contributions to the development of New China, was elected as one of the 100 moving Chinese characters since the founding of New China in 2009.

Li Siguang graduated from Osaka Higher Technical School in Japan in July 1910; In 1911, he served as the Minister of Industry of the Hubei Army; In January 1928, he was appointed as the director of the Institute of Geology of the ** Research Institute; In 1948, he was elected as an academician of the ** Research Institute; In May 1950, he was appointed Vice President of the Chinese Academy of Sciences. In April 1951, he was elected Vice Chairman of the Executive Committee of the World Association of Scientists. In September 1952, he was appointed Minister of Geology of the People's Republic of China; In 1955, he was elected as a member (academician) of the Chinese Academy of Sciences; In September 1958, he was appointed as the chairman of the China Association for Science and Technology; In April 1969, he was elected as a member of the 9th ** Committee of the Communist Party of China; In August 1970, he served as the head of the science and education group.

Li Siguang founded geomechanics and made important contributions to the development of China's petroleum industry. In his early years, he had superb research on the fossils of the family and their stratigraphic significance, proposed the existence of Quaternary glaciers in eastern China, established the concepts of "geomechanics" and "tectonic system" in the new marginal disciplines, and established the school of geomechanics. This paper proposes the understanding of the broad prospect of oil prospecting in the three subsidence zones of the New China tectonic system, and creates a forecasting method that combines active tectonic research and in-situ stress observation.

Since childhood, he studied in a private school taught by his father Li Zhuohou. At the age of 14, Li Zhonghua said goodbye to his parents and came to Wuchang alone to apply for the higher primary school, when filling out the registration form, he mistakenly took the name column as the age column, and wrote down the word "fourteen", and then changed the "ten" to "Li", and then added the word "light", and changed his name to Li Siguang, and since then he has been known as "Li Siguang".

In May 1904, Li Siguang went to Japan to study at official expense and entered the general department of Tokyo Hongwen College; In December of the same year, Li Siguang became acquainted with Song Jiaoren, a modern democratic revolutionary who was studying at Hosei University in Tokyo at that time, and was introduced by Song Jiaoren to Ma Junwu, who was studying process chemistry at Kyei University in Tokyo. At this time, he embraced more ideas of democratic revolution and began to embark on the path of revolution. And resolutely cut off the long braid coiled around his head, showing that he was on the side of the revolution.
