中文摘要：

不同时空尺度的岩石圈内部变形会在重力异常场中形成不同波长特征的永久记录.最早的重力均衡学原理提出主要用于解释实测地形与重力异常之间的关系.从早期Airy/Pratt均衡的局部补偿模式,发展到后期的区域均衡模式及弹性板均衡模型的提出,已逐渐形成了以岩石圈有效弹性厚度为核心的一种评价体系,主要用于度量岩石圈的力学强度特性并表征其相应物理属性.相关研究已经成为岩石圈动力学研究的热点之一.本文将从实验均衡原理出发,通过系统总结重力导纳方法的发展,介绍岩石圈有效弹性厚度概念和力学各向异性方面的研究进展为主线,以基本原理和相关概念的定义入手,系统总结了近年来相关方面的研究成果及重要进展.

英文摘要：

It made the permanent records of gravity anomaly field with numerous wavelengths as the inner flexure of the lithosphere at spatial or temporal multi-scale.As we known,the main aim was to explain the relationship between the topography and gravity anomaly using the isostasy hypothesis.From the Airy or Pratt isostastic model as the local compensation model,to the regional compensation model as well as the flexure isostasy,the evaluation system was formed which focused on the problem of lithospheric effective elastic thickness（EET）.The EET parameter used to evaluate the mechanical strength of lithosphere and its relative physical property.The relative researches have become the highlights on the geodynamic field.In this paper,we firstly give an introduction on the experimental isostasy method and make a summary on the development of gravitational admittance.Secondly,we focused on the EET concept,principle and method and further to systematically summarize the relative research progresses in this field.
