摘　　要：利用云南地区1951—2011年的水准复测资料,计算获得了1951—1980年、1980—1994年、1994—2011年、1951—2011年的垂直形变速率图和各个阶段的形变增量场,结合该区的地震活动,研究了垂直形变与地震的关系。结果表明:7级以上地震主要发生在上升区,与区域性上升有关;地震多数发生在垂直形变速率增量场的正值区。On the basis of the muhi-phase re-leveling data of Yunnan area obtained from 1951 to ：2011, the vertical variation rate chart of 1951 - 1980, 1980 - 1994, 1994 -2011 and 1951 -2011 been drawn. Through combining the earthquakes happened in this area, the relationship between the vertical variation and the earthquake had been researched as well. The results indicate that the earthquakes of stronger than 7 level were mainly hap- pened in rising area. The earthquake mostly happened in the area of positive value in rate field of incremental verti- cal deformation.
