基于GPS获得的中国大陆现今地壳运动速度场

摘要/Abstract

摘要： 利用国家重大科学工程“中国地壳运动观测网络”1999至2011年底的全部GPS观测资料，采用统一的数据处理策略和最新的地球物理模型，分别获取了中国大陆相对于全球ITRF2005参考框架和欧亚板块的现今地壳水平运动速度场。通过速度场分析，给出了中国大陆地壳运动的大背景和基本特征，为地震预测、地球动力学等相关学科的研究提供了基础资料。

Abstract: With unified processing strategies and updated geophysical models, we calculated respectively the present-day crustal movement velocity field with respect to ITRF 2005 and Eurasian plate in mainland China derived from 1999—2011 GPS observations of the Crustal Movement Observation Network of China which was an important fundamental scientific engineering project in China. The velocity field reveals the large background and basic characteristics of crustal movement in mainland China, which can provide important information for research of earthquake prediction, geodynamics and so on.

Key words: Crustal movement, Velocity field, Crustal Movement Observation Network of China, GPS, Mainland China
