地体分析是80年代大地构造学的一个前沿课题。地体概念的提出是板块构造学的一项重要发展,它进一步促进了人们地球观的根本变化。用地体观点来描述地球的详细历史,是现代地质学面临的新挑战。论文就地体的性质及其位移、地体的融合、添加和分散作用,以及从地体分析角度对环太平洋大陆生长过程的研究现状等方面作了简要的介绍。 Geoanalysis is a frontier subject of geotectonics in the 1980s. The concept of terrain is an important development of plate tectonics, which further promotes the fundamental change of people’s view of the earth. Describing the detailed history of the earth from the point of view of the earth is a new challenge that modern geology faces. The dissertation gives a brief introduction of the nature and displacement of the earth body, the integration, the addition and the dispersion of the earth body, and the research status of the growth of the Pacific Rim continent from the point of view of the earth body.
