摘要: 自然因素或人类活动可使地球表层或内部应力发生变化,进而产生灾害事件。获取灾害事件与灾害过程的关键地学参数对于准确理解灾变过程、科学解释灾变机制、正确拟定应对策略具有重要意义。InSAR技术已广泛应用于自然因素或人类活动导致的灾害事件与灾变过程的参数反演。本文首先介绍了InSAR卫星的发展和地表形变监测的基本原理;然后分析了InSAR地学参数反演在地震、火山活动、地下水抽取、矿山开采、冻土冻融、冰川运动、地下流体迁移等各类潜在致灾事件中的研究现状;最后分析了InSAR地学参数反演存在的主要挑战和问题。

Abstract: Natural factors or human activities can alter the stress of earth surface or its interior part, which generally causes disaster events. Obtaining the key geoscience paramters of disaster events and their developing progress is essential for us to accurately understand the disaster progress, scientifically interpret the disaster mechanism, and properly formulate acting strategy. InSAR is widely used in the parameter inversion of disaster events and their developing progress caused by natural factors or human activities. This paper firstly introduces the development of InSAR satellites and the basic principles of InSAR surface deformation monitoring. Subsequently, the research status of InSAR geoscience parameter inversion in various disaster-causing events is summarized, including earthquake, volcanic activity, groundwater extraction, mining, permafrost freezing and thawing, glacier movement, and underground fluid migration, etc. Finally, we conclude the main challenges and issues of InSAR geoscience parameter inversion.

Key words: spaceborne SAR, InSAR, ground surface deformation, geoscience parameters inversion
