利用GPS观测结果对我国地壳水平形变强度的分析
Analysis on the intensity of horizontal crustal deformation in China based on results of GPS observations
【摘要】 介绍利用中国地壳运动观测网络区域网(包括基本网与基准网)1999年与2001年2期GPS观测所获得的中国大陆地壳水平位移速率结果,研究块体的划分、块体位移与块体变形,提出了用位移(速率)离散度分析块体或局部水平变形强度的方法,分析了中国大陆现今地壳运动的基本特征及2001年11月14日昆仑山口西8.1级大地震前的地壳水平运动。
【Abstract】 The result of horizontal crustal movement in China′s continent, obtained from 2 epochs of GPS observation in the regional network (including the basic network and the fiducial network) of the Crustal Movement observation Network of China (CMONOC) carried out in 1999 and 2001, is introduced. Division of blocks and their deformations are analyzed. An approach to analyze the intensity of horizontal crustal deformation in localized areas or on blocks in term of displacement velocity dispersion is proposed. The general characteristics of the recent horizontal crustal movement in China’s continent and the horizontal crustal movement before the Kunlun Mountain earthquake with M8.1 on Nov. 14, 2001 are analyzed.
