摘要
叙述了１９８９年大同一阳高地震地壳形变的主要特征，指出其具广泛性、多样性和阶段性。分析了这次地震前后大地形变场的动态和演化，并从不同时空尺度对这次地震后华北地区形变场的新格局和未来地震形势进行了讨论。
The main characters of the crustal deformation of 1989 Datong-Yanggao earthquake were described,and its extensivity, diversity and periodicity were pointed out. The dynamic state of the ground deformation field before and after the earthquake and the evolution were analyzed, and the new format of the deformation field in North China and the future earthquake trend after the earthquake were discussed from different time space scale.
