What outstanding contributions has Li Siguang made to China s modernization?

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. [1][2][3]

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 the early years, he had superb research on the fossils of the Flyflies and their stratigraphic significance, put forward the existence of Quaternary glaciers in eastern China, established the concepts of "geomechanics" and "tectonic system" in the new marginal disciplines, established the concept of "tectonic system", and founded 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.

The main content of the Meiji Restoration is explained in the 101 education ppt: In 1950, after Li Siguang overcame many difficulties and returned to the motherland, he was anxious about the country's urgency, used his scientific research results, and served the modernization construction, and made many achievements, the most important of which was to use his original geomechanical theory to put forward a set of theories and methods for finding oil. Accordingly, China's exploration departments have successively found large oil fields such as Daqing, Dagang, and Shengli, enabling China to take off the hat of "poor oil" in one fell swoop and provide energy guarantee for the country's economic construction.

Li Siguang also used the theory of geomechanics as a guide to find uranium ore resources, and made contributions to the development of China's nuclear energy industry; He also used this theory to conduct effective research on forecasting.

Guang (1889-1971) was a Chinese geologist and the founder of geomechanics. 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 been engaged in the research of paleontology, glaciology and geomechanics for a long time, and has made outstanding contributions in the identification of paleontological fossils, the discovery of Quaternary glaciers in China, and the establishment of geomechanics.

Li Siguang's contribution to the history of science is the establishment of geomechanics, a new marginal discipline. He is the author of the book "Concepts of Geomechanics", which argues that the deformation of rocks in the movement of the earth's crust is due to the action of in-situ stress. In July 1947, he represented China at the 18th International Geological Congress, and for the first time applied the geomechanical theory he founded, and gave an academic report entitled "The Origin of the New China Sea", which aroused strong repercussions.

1.Li Siguang is one of the pioneers of geology in China, founded geomechanics and made important contributions to the development of China's petroleum industry.

2.In his early years, he had excellent research on the fossils of the Flyidae family and their stratigraphic significance. The existence of Quaternary glaciers in eastern China was proposed. From the perspective of mechanics, the movement of the earth's crust and the distribution of minerals are studied, and a new concept of "geomechanics" and "tectonic system" is established.

3.He advocated the study of the occurrence, development and combination of geological structures from the perspective of mechanics, believed that various tectonic traces were the result of in-situ stress activities, established the concept of "tectonic system", and founded the school of geomechanics.

4.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.

In a short period of time, he successively discovered the oil fields of Daqing, Shengli, Dagang, North China, Jianghan and other oil fields, and established immortal feats for China's petroleum industry. From the late 50s to the 60s, the exploration department successively found the Daqing Oilfield, Dagang Oilfield, Shengli Oilfield, North China Oilfield and other large oil fields, which made the rolling oil emerge when the country was in urgent need of energy. In this way, not only did he take off the hat of "China's poor oil", but also made Li Siguang's original geomechanical theory the most powerful proof.

6.The "astronomical, geological and paleontological data" published in his later years had a profound impact on the advocacy of interdisciplinary research in China. It has made great contributions to the development of geological education, geological science and geology in China.

He is the author of "The Main Causes of the Change of the Earth's Surface Image", "The Science of China's Northern Training", "Geology of China", "Lushan in the Ice Age", "Introduction to Geomechanics" and the anthology "Astronomy, Geology, Paleontology".

Li Siguang is a famous geologist in our country, he has made great contributions to our country's petroleum industry, we all know that oil is the blood of industry, the development of industry is inseparable from oil, the development of industry leads us to the world, to achieve the great rejuvenation of the Chinese dream.

You are an outstanding person who has realized the dream of becoming a strong country, and I think you can say that you have made a great contribution in the world.

Li Siguang (1).

Huanggang is the seat of the state capital of the past dynasties, also known as Huangzhou. It is located in the southeast of Wuhan, on the north bank of the Yangtze River, across the river and Echeng, and is an important gateway of Hubei Province.

Lower Zhangjiawan is 25 kilometers north of Huanggang County, and is a small village with only a dozen households. Nowadays, the village no longer exists, and the local people's commune has built a reservoir here, called Huilong Reservoir.

It was on such a piece of land that Li Siguang began his childhood.

Li Zhuohou studied with Curry since he was a child, and when he grew up, he became a "poor talent". He inherited his father's business and worked as a tutor for the rest of his life.
