巴颜喀拉块体及周缘是近年来中国大陆大震主要发震区域之一，2013年4月20日四川省芦山7．0级强烈地震就发生在巴颜喀拉块体东缘的龙门山断裂带的西南段上。以巴颜喀拉块体中东段为研究区，通过对该区域地震前后的多期区域水准观测数据和 GNSS 连续站观测数据进行计算处理，得出研究区垂直形变速率图像和水平形变速率图像；结合区域地质构造，建立地震诱发模型，解释芦山地震主震发震和余震活动源于龙门山断裂带中大型块体的突然断裂和小型块体集合的流动机制；通过对垂直形变速率图像和水平形变速率图像的分析，认为芦山地震是龙门山断裂带逆冲活动的结果，东昆仑断裂带中东段未来大震发生的可能性增大；提出未来5年基于区域水准测量和 GNSS 测量为技术手段的监测建议。

Bayan Har block and peripheral is one of the main seismogenic area of mainland China in recent years,on April 20,2013 Sichuan Lushan 7.0 strong earthquake was happend on the southwest segment of Longmenshan fault zone,the east margin of Bayan Har block.We take the middle-east segment of Bayan Har block as the research area,based on the proseccing of observation data come from the before and after the earthquake in this region by multiphase regional level observation and GNSS station observation,it can be obtained the study area image for both of the horizontal and vertical deformation rate.Combined with regional geological structure,the earthquake induced model was established,and the explaination for the main shock and aftershock earthquake activity mechanism come from the sudden rupture of Longmenshan fault zone for the huge blocks and small block the flow of the collection.By analyzing the image both of the vertical deformation rate and horizontal deformation rate, we conclude that the earthquake was the result of the Longmenshan fault zone thrust activity,and the middle east section of east Kunlun fault zone appear the possibility of strong earthquakes occurred in future.At last,the monitor based on the regional level and GNSS measurements in the next five years is suggested as for the technical means.
