| 摘 要： | 近年华北地区GPS水平形变反映出阴山－燕山南缘构造带、张家口－蓬莱隐伏断裂带、郯断裂带及建昌－邢台构造带具有较强的活动性，成为不同时间的压缩区段。近年的基线和位移量的表明：形变压缩区和位移量较大的地区是地应力积累较大地区，因此，成为中、强地震发生的场所，这两项可作为判定地震危险区的标志。

| Abstract: | The decent GPS horizontal deformation reveals a strong activity along the structure belt of southern herder of Yinshan-yanshan, the Zhangjiakou-Penglai buried fault belt, the Tancheng-lujiang fracture belt and the Jianchang-Tanshan-Xingtai tectonic belt, forming a compressive region of different time. The recent baseline and displacements show that the regions of compressive deformation and larger displacements are the regions of larger accumulated stress, and also the regions of GPS seismogenic moderate or strong. The compressive deformation and larger displacement can act as the mark to decide the seismic risk region. |
