| 摘 要： | 利用云南地区1982~2013年跨断层基线和水准观测资料，计算走滑量和张压量及其累积变化量，并结合7级及以上地震进行分析。结果发现，云南地区断层活动在时间上存在明显的分段特征，在空间上活动程度也不一样；断层与地震的关系主要表现为震前断层活动增强，同震使断层活动改变，震后断层活动也会存在减弱或增强。

| Abstract: | This paper calculates slip and pressure amounts and the cumulative amount of change for studying the fault activity characteristics in the Yunnan region, using the cross fault baseline and leveling observation data from 1982 to 2013. Combined with analyzing earthquakes at magnitude 7 and above in this region, the results show that there are obvious segmentation features during the time of fault activity in the Yunnan area, and that there are obvious differences in space activity. The relationship between faults and earthquakes mainly shows that: when the pre-earthquake fault activity is enhanced, the coseism fault activity can be changed, and the after earthquake, activity will be weakened or strengthened. |
