【摘要】：利用PANDA軟件計(jì)算2011-01~2014-10"陸態(tài)網(wǎng)絡(luò)"所有基準(zhǔn)站的單日解坐標(biāo),并采用QOCA軟件解算基準(zhǔn)站水平運(yùn)動(dòng)速度場(chǎng)。分析顯示,PANDA軟件水平定位精度達(dá)到2mm,且根據(jù)QOCA軟件計(jì)算的"陸態(tài)網(wǎng)絡(luò)"基準(zhǔn)站水平運(yùn)動(dòng)速度場(chǎng)與中國(guó)地震局發(fā)布的速度場(chǎng)互差RMS在東西、南北方向分別為1.12mm/a、0.95mm/a,表明計(jì)算結(jié)果準(zhǔn)確、可靠。在此基礎(chǔ)上,基于速度場(chǎng)數(shù)值結(jié)果描述了中國(guó)大陸相對(duì)歐亞板塊的水平運(yùn)動(dòng)速度場(chǎng)的空間分布特征。
[Abstract]:The single-day solution coordinates of all datum stations in 2011-01 / 2014-10 "land state network" are calculated by using PANDA software. The horizontal moving velocity field of the reference station is calculated by QOCA software. The analysis shows that the horizontal positioning accuracy of Panda software reaches 2mm, and the horizontal velocity field of the "land network" reference station calculated by QOCA software and the speed issued by China Seismological Bureau. The degree field difference RMS is in the east and west, The north and south directions are 1.12 mm / a 0.95 mm / a respectively, which shows that the calculation results are accurate and reliable. Based on the numerical results of the velocity field, the spatial distribution characteristics of the horizontal velocity field of the Chinese continent relative to the Eurasian plate are described.
