全球构造研究的简要回顾

全球构造研究可分为：（１）１９世纪后期“固定论”占统治地位阶段；（２）２０世纪６０年代前“活动论”曲折发展阶段；（３）６０年代以来板块学说占统治地位阶段。当代全球构造研究以地球深部构造与物质研究为关键。日本学者提出了“幔柱构造”和新的全球构造体系，其它学者提出了不同形式的“膨胀论”和“脉动论”。全球构造研究应注意思想创新，冲破均变论思想的局限性。建议以突变观点和“阶段论”为依据，使观察、推理和实验三者适当配合，发挥优势，逐步建立自己的地球动力学及其演化模型。

RETROSPECT OF THE STUDY ON GLOBAL TECTONICS

Three stages in the development of the study on global tectonics may be recognizedin the past century and a half. These are:(1)Fixism dominating stage in the late 19th century,(2 ) Tortuous development stage of mobilism before the sixties of the 20th century,and(3)Plate tectonics dominating stage since the sixties. At present,the study of the earth’s deep inte-rior is a key problem.The Japanese geologists advanced recently their plume tectonics and newwhole earth tectonics. Other geologists proposed earth expansion and pulsation in variousforms.For the time being it seems desirable to break through the constraints of existing preva-lent theories and avoid too much uniformitarian way of thinking,It is deemed tenable to baseour idea on mobilism in global tectonics and punctuated progression by stages in historical de-velopment,and a limited,pulsative and assymmetric earth expansion may be taken as a workinghypothesis. A good combination of selected observational,experimental and theoretical workmay afford in due time to establish our own model of the earth dvnamics and its evolution.
