摘要
利用PANDA软件计算2011-01～2014-10＂陆态网络＂所有基准站的单日解坐标,并采用QOCA软件解算基准站水平运动速度场。分析显示,PANDA软件水平定位精度达到2mm,且根据QOCA软件计算的＂陆态网络＂基准站水平运动速度场与中国地震局发布的速度场互差RMS在东西、南北方向分别为1.12mm/a、0.95mm/a,表明计算结果准确、可靠。在此基础上,基于速度场数值结果描述了中国大陆相对欧亚板块的水平运动速度场的空间分布特征。
Using PANDA software,all data of continuous stations of crustal movement observation network of China（CMONOC）are calculated to obtain continuous single day coordinates,while the corresponding horizontal velocity field is built through QOCA software.Analysis demonstrates that the precision of horizontal positioning of PANDA software reaches 2mm,while differences root mean square（RMS）between the horizontal velocity field calculated by QOCA software and the horizontal velocity field published by China Earthquake Administration are 1.12mm/a and 0.95mm/a in eastwest and south-north directions respectively.Ultimately,based on calculated velocity filed results,the main characteristics of spatial distribution of crustal horizontal movement of the Chinese continent are described.
