摘　　要：分析了祁连山—海原断裂带跨断层形变近期异常变化特点，给出了该断层形变区域特征异常量，认为断层形变不但能够显示局部构造活动，而且可以反映大范围地壳形变波的空间传播与演化。In this paper,the recent abnormal features of across fault deformation measurement on Qilianshan—Haiyuan fracture belt are analyzed.The result shows that across fault deformation not only can mirror regional tectonic movement,but also reflect the space evolution of crustal deformation wave in large area.This provides a physical background for tracing and predicting earthquakes using across fault data.
