【摘要】：利用PANDA軟件計算2011-01~2014-10"陸態(tài)網(wǎng)絡(luò)"所有基準站的單日解坐標,并采用QOCA軟件解算基準站水平運動速度場。分析顯示,PANDA軟件水平定位精度達到2mm,且根據(jù)QOCA軟件計算的"陸態(tài)網(wǎng)絡(luò)"基準站水平運動速度場與中國地震局發(fā)布的速度場互差RMS在東西、南北方向分別為1.12mm/a、0.95mm/a,表明計算結(jié)果準確、可靠。在此基礎(chǔ)上,基于速度場數(shù)值結(jié)果描述了中國大陸相對歐亞板塊的水平運動速度場的空間分布特征。
[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.
