【摘要】 分析了北祁连河西地区近期大地垂直形变演化特征，结果表明，该地区地壳形变逆继承性运动弱，继承性运动强。研究了垂直形变异常与地震的对应关系，地震发生在垂直形变隆起区的边缘形变高梯度带上。指出该地区的中段形变异常明显，已形成强震的孕震背景。更多还原

【Abstract】 The evolutional characteristics of recent vertical deformation field are analyses in earthen Qilian-Hexi area, the result indicates that crustal converse successive movement in this area appeared weakly, and the successive movement appeared strongly. And the corresponding relationship between crustal deformation and earthquake is researched, the earthquake oc curred in high gradient belt along the edge of vertical deformation upward district. The crustal deformation anomaly is indicated obviously in the middle part of this area .it is got into the background of pregent strong earthquake.更多还原
