摘　　要：通过分析云南西南部1988、1991和2012年3期精密水准观测数据,获取了区域现今地壳垂直运动速度场。结果表明:龙陵—澜沧断裂带上的永德—永康段相对于周围区域的运动处于快速隆起状态,结合地震分布和构造地质等方面资料,认为该地区为一个中强震长期危险区域。Analyzing the precise leveling observation data in 1988, 1991 and 2012, we obtained the present crustal ver- tical movement in the southeast of Yunnan Province. The result shows that the vertical movement velocity field of Yongde-Yongkang segment in the middle of Longling-Lancang Fault uplifts quickly compared to its surrounding ar- ea. Combing the distribution of earthquakes and the geological structure etc. , this region is regarded as a middle and long term strong earthquake risk area.

关 键 词：龙陵-澜沧断裂 速度场 同震形变 震后形变 危险区
