我国动力大地测量学的进展

综合了近40年,特别是近10年来我国利用大地测量学、地球物理学和天体测量学的理论、方法和技术研究固体潮汐和非潮汐重力、地极移动和自转速率变化、大地水准面和海平面变化、板块运动和地壳形变、地球内部物质运动及其与地表变化的关系等五个方面的成果以及国际合作的情况,说明我国在动力大地测量学方面虽然起步较晚,但进展较快,已在生态环境、灾害预测预报等关系国计民生的研究中起到了一定作用,在国内国际的地学研究中占有一席之地。随着国际大地测量协会“亚太空间动力学研究计划”、国家攀登计划项目“现代地壳运动和地球动力学研究”、国家大型科学工程重大项目“中国地壳运动观测网络”等项目的启动、实施,动力大地测量学研究必将取得快速进展。

PROGRESS OF DYNAMIC GEODESY IN CHINA

The achievements and international cooperation of studies in five aspects, such as earth tide and non-tidal gravity, Earth polar displacement and variation of rotation rate, geoid and sea level change,plate movement and crustal deformation, movement of the matter within the earth' s interior, by the theory, method and technique of geodesy, geophysics and astrometry in near four decades, especially the recent decade, is summered in the paper. Despite of late launch of the study on dynamic geodesy in China,the progress is fairly rapid. It plays a certain role in the eco-environment and hazard prediction related to the national economy and people' s livelihood, as well as takes a proper place in the domestic and international geoscience research. With the launch and implement of several projects, such as the“Plan of Geodynamics in Asian and Pacific Region”, National Climbing Project“Modern Crustal Movement and Geodynamics Research”, National Key Scientific Engineering Project“Observation Network of Crustal Movement in China”, studies on dynamic geodymics must be progressing rapidly.
