中文摘要：

利用武汉大学卫星导航定位技术研究中心编写的精密定轨定位软件对新疆31个＂陆态网络＂GNSS基准站2011年1月4日至2014年12月31日30 s数据进行区域地壳形变特征分析。结果表明,新疆西南部受印度板块的推挤其南北向运动变化速率较大,受塔里木盆地的阻挡作用,其东西向运动速率最小,盆山结合部垂直运动变化梯度值较高。天山中段北南分量运动变化过渡平缓,而东西分量展现了其运动与断层的相对关系,垂直向运动速率差异性较大,显示出盆山结合带处于垂直运动速率变化的高梯度区。山体内部垂直运动为趋势上升,表明天山处于隆升状态。地壳的水平向与垂直向整体运动变化趋势,直接说明新疆南天山与昆仑山交汇区域已聚积大量能量,是中强震甚至是7级以上强震发生的优势区域。北天山中段巴音布鲁克一带是垂直运动速率变化的高梯度带,这一区域可能是未来中强震发生的优势区域。

英文摘要：

Using GNSS data of China Crustal Movement Observation Network（ CMONOC）,and PODAP software which was developed by Satellite Navigation Institute of Wuhan University,the writers calculated 31 GNSS stations＇ data from July 1st,2011 to December 31 st,2014,sampling at 30 seconds,and studied regional crustal deformation characteristics. Analysis results showed that in southwestern Xinjiang,the NS movement rate was influenced by Indian plate pushing. Under the blocking effect of Tarim Basin,EW movement rate was slightly smaller. In north Tianshan area vertical dimension movement rate was quiet different,which showed a high gradient zone in the combination area of the basin and the moutain. On region overall characteristics,the writers considered that the intersection region from south Tianshan and Kunlun Mountains were seismogenic area advantages,especially moderate-strong earthquakes,even more than 7 earthquakes. Middle of North Tianshan was the turning point of vertical movement rate around Bayinbuluke,also was the high gradient zone of the vertical movement,which area was also advantage region of the strong earthquake in future.
