李四光（1889~1971）地质学家。湖北黄冈人。字仲揆。早年加入同盟会。参加了辛亥革命。1919年毕业于英国伯明翰大学，获硕士学位。1920年回国。曾任北京大学教授、中央研究院地质研究所所长。从事古生物学、冰川学和地质力学的研究和教学工作。建国后，历任中国科学院副院长、中科院古生物研究所所长、地质部部长、中科院地学部委员、中国科协主席，第二至四届全国政协副主席。1958年加入中国共产党。是中共第九届中央委员，第一至三届全国人大代表。中国地质力学的创立者。主张用力学研究地壳现象、探索地壳运动与矿产分布的规律，把各种构造形迹看作是地应力活动的结果，从而创立了“构造体系”的基本理论。用此理论分析中国东部地质构造特点，认为新华夏构造体系的三个沉降带具有大面积储油层。在地震地质工作方面，主张在研究地质构造活动性的基础上观测地应力的变化，为实现地震预报指明了方向。著有《中国地质学》、《地质力学概论》、《地震地质》、《天文、地质、古生物》等。
Li Siguang (1889 ~ 1971) geologist. Huanggang, Hubei people. Zhongkui word. Early accession to the United League. Participated in the Revolution. 1919 graduate of the University of Birmingham, was a master's deGREe. Return in 1920. A former professor at Beijing University, director of the Academia Sinica Institute of Geology. Engaged in paleontology, geology, glaciology, and the mechanics of research and teaching. After the founding of the PRC, the former vice president of the Chinese Academy of Sciences, Chinese Academy of Sciences Institute of Paleontology and Geology Minister, Xuebuweiyuan to the Chinese Academy of Sciences, Chairman of the China Association for Science and Technology, to a second four-time vice chairman of the CPPCC National Committee. In 1958 to join the Communist Party of China. Communist China is the ninth member of the Central Committee, in the first, second and third terms on behalf of the National People's Congress. Chinese geological mechanics of the founder. Mechanics Research favor of the crust, and crustal movement to explore the distribution of mineral laws of the various structural features as a result of activities to stress, which created the "structural system," the basic theory. With the theoretical analysis in the eastern Chinese geological features, that the new structure of the Chinese system of the settlement with the three reservoirs have a large area. In geological seismic work, that the study of geological activity on the basis of observing the changes in stress, earthquake prediction for the realization of the direction. The "China Geology" and "Introduction to geomechanics", "geological earthquake", "astronomy, geology, paleontology," and so on.
