摘要
青藏高原复杂的质量迁移伴随着重力场的变化,利用时变重力研究青藏高原质量迁移成为一个重要的科学问题。重力卫星GRACE的应用,为人们了解青藏高原质量迁移规律和特征提供了重要的观测手段,也为青藏高原地球动力学问题提供了新的研究方法。相较于传统的陆地重力观测技术,GRACE实现了对全球连续的重力观测,其数据能够用于大尺度质量迁移问题的研究,而在青藏高原区域的应用更能显示卫星重力的独特优势。综述十多年来利用时变重力数据研究青藏高原上的质量迁移问题的最新进展,特别是总结了造成质量变化的各种因素(冰雪融化、湖泊水位变化、地下水变化、构造运动等)的研究现状、科学成果、存在问题和发展方向。
The complex mass migration in the Qinghai-Tibet Plateau is accompanied by the change of gravity field,and it is an important scientific problem to study the mass migration of the Qinghai-Tibet Plateau by using time-varying gravity.Application of gravity satellite GRACE(gravity recovery and climate experiment)provides an important observation means for us to understand the mass migration characteristics of the Qinghai-Tibet Plateau,and provides a new approach for studying the geodynamics of the Qinghai-Tibet Plateau.Compared with traditional land-based observation,GRACE realizes global and continuous gravity observation,and enable to study the larger scale problems about mass migration,and satellite gravity shows unique advantage in the research over Qinghai-Tibet Plateau areas.This paper reviews the latest progress in the study of mass migration over the Qinghai-Tibet Plateau using time-varying gravity data over the past ten years,especially the research status,scientific achievements,and existing problems of various factors causing mass change(ice and snow melting,lake water level change,groundwater change,tectonic movement,etc.).
