摘　　要：利用中国地壳运动观测网络及部分测绘部门GNSS连续运行跟踪站近年来的GPS观测资料,获得了巴彦喀拉及其周边地块的现今地壳运动特征,并采用应变分析模型获得了该区域的现今地壳构造应变分布特征。Present crustal velocity field and distribution features of present tectonic strainin in Bayan Har block and its surroundings were calculated with GPS data of CMONOC and GNSS continuous tracking station,using the graphic element strain model. The calculaed results were compared with the geodynamic background.
