| 摘 要： | 利用多期地形变监测资料，研究了祁连山－河西走廊地区七十年代初至今的大地垂直形变演化与构造活动特征。认为，构造形变特征与青藏高原挤压作用为主导的区域应力场消长变化有关，目前祁连山相对走廊盆地下沉，具有较弱的逆继承性运动特征，表明在１９８８～１９９０年青藏块体应变能大释放之后区域应力场处于松驰、调整阶段

| Abstract: | Based on the monitoring data of crustal deformation, the characteristics of the vertical deformation and tectonic activity in Qilian mountian-Hexi corridor area since the 1970s are studied. It is concluded that the Qilian mountian sinks relatively to Hexi corridor basin and makes a feature of weak inherited inverse motion at present, which shows that the stress field in the area is in a period of relaxation and adjustment after the strain energy in Qing-Zang block released from 1988 to 1990. |
