如何利用地表观测数据真实解析地球内部运动状态与演化图像是地球科学家探索地球奥秘的关键和梦寐以求目标。本项目基于申请者提出的地球内部变形和密度变化耦合时变运动模式理论，从地球内部整体时空运动角度，着力发展研究利用现代大地测量技术获取的地表动态重力变化和位移形变变化信息来综合确定地球内部介质动态变形运动和密度变化的“耦合迭代解算” 技术与方法；考虑到反演计算技术发展与现实要求，针对地球结构具有整体分层与局部分异的特点，重点实现“分层界面时变”、“局域时变体”及其“组合”情形下的实用正反演软件技术；在此研究基础上，利用青藏高原东南缘地区多年来丰富的重复重力、GPS和水准成果，以地质地球物理深部成果构建地壳运动的简化模型与约束参数，来定量模拟和反演确定区域地球内部介质的变形运动和密度变化的动态图像，为多学科整体、定量研究大陆地壳深部构造运动和大陆动力学解释提供有效的新方法和新途径。

It is a key and dreamed aim of groscientists how to resole the crustal movements and show the figures of their evolution by observation data on surface. In this research project, base on the theory of coupling movement between crustal deformation and density change proposed by applicant, deformation and density change of the earth's interior media would ce computed synthetically using the modern geodetic data of changes about dynamic gravity, deformations ans displacements. Taking the eastern part of the Tibetan Plateau, we will focus on the method and technique of "coupling iterative inversion". With global delamination and local differentiation, the key achieve practical software of forward modeling amd inversion under "the time-varying of stratified interface" and "local time-varying body". Accrding to above study and many years data of resurveying gravity, GPS and leveling in the southeast edge of Tibetan Plateau, deformation and density change of the earth's interior media would be simulated and inverted, used initial framework of crustal movements which built by geological and geophysical achiveements firstly. Furthermore, the dynamic figures of deformation and density change will be obtained. And it made a forward step in effective new solution and method for tectonic movements of deep earth and explanation on continental dynamics.
