摘　　要：通过收集相关监测点在尼泊尔地震前后的数据,采用统一的模式进行数据处理,将震前与震后的形变监测成果归算到ITRF2008参考框架和2015.315(2015年4月25日)历元,计算得到监测点的平面变化和高程变化,对监测点的形变进行分析,得出2005年5月至2015年5月之间,珠峰地区地形变化的情况。By collecting the data of monitoring points before and after the Nepal earthquake,adopting the same mode to process data,unifying the result of variety monitoring before and after earthquake towards reference frame of ITRF2008 and epoch of 2015.315,calculating the variety of monitoring points in level and altitude,and analyzing the variety of monitor points,author thinks the Everest area was moving northeastward at speed of 4cm per year and rising at speed of 0.3cm per year from May of 2005 to May of 2015;the 4.25 earthquake made the Everest area move southwestward about 3cm and sink about 0.7cm;and 5.12 earthquake had few influence on the Everest area.
