| 摘 要： | 根据华北地区GPS观测数据计算了华北活动块体的运动速度和应变率,以及块体边界带的活动速率和应变率,研究了华北块体的运动和应变率特征,以及边界断裂带的应力作用特征.形变揭示出华北亚板块从西向东运动方向由东向偏转为南东向,NE-NNE向断裂带呈现右旋,NWW-EW向断裂带呈现左旋.各个次级块体的主压应变应力轴方向存在一定的...

| Abstract: | On the basis of the GPS data of Chinese Crustal Motion Network in North China,the velocities and the strain rates on blocks in North China were calculated,as well as these on block's boundary fault zones.The North China subplates' motion and features of the strain rate,and also the features of the strain stress of the block's boundary fault zones were studied.The results show that the direction of the west-east movement field of North China subplates turns from east to southeast,the NE-NNE fault zone is of ... |
