摘　　要：以块体活动边界及地震活动性为目标,对南北地震带和华北等我国部分区域(189处,248条)跨断层水准测量资料用统一的方法和标准进行了处理和分析。将这些断层形变资料分布的测点分成不同的区带,分别统计断层平均活动速率和断层活动的力学性质,对其空间分布、个体特性及其可能与地震活动之间存在的关系展开了讨论,并对各区带孕育发生较强地震的可能性给出了初步的判定。In order to study the active boundaries of crustal blocks and seismic activity, all the data of 248 short leveling lines across faults from 189 sits in eastern China including North-South Belt are processed and analyzed with the same method and standards in this paper. According to their distribution, the sites are divided into different areas and belts. The average rate of fault activity and its mechanical property are calculated and analyzed respectively for different areas and belts, and then discussion on the relation between seismic activity and characteristics of fault activity and its distribution is made. Finally, the probability for strong earthquake occurrence in different areas or belts is discussed.
