| 摘 要： | 通过复测得到的全国19 个GPS点之间两年内(1994 ～1996 年) 的基线长度变化,表明我国西部形变量远大于东部。表现为西部北东向、近南北向基线多为缩短,北西及东西向基线伸长:华北则北东、东西向基线缩短,而北西向基线伸长;华南变化稍大,以北西西向基线缩短为多,北东向基线主要为伸长。缩短基线与震源机制解中P轴方向基本一致,而伸长基线多与其正交或斜交

| Abstract: | Baseline changes of 1994—1996 between 19 GPS points across the country have been observed through remeasurement. The data indicate that deformation of western China is much greater than that of eastern China. In the west most of the baselines of NE or nearly SN direction are shorten and those of NW or EW direction are extended. In North China the NE and EW baselines are shorten while NW baselines are extended. In south China most of NWW baselines are shorten and NE baselines are mainly extended. Orientation |
