| 摘 要： | 利用＂中国大陆构造环境监测网络＂新疆地区的基本站、区域站观测成果对天山及邻近地区现代地壳运动进行了研究,获得了天山地壳运动速率,提出了天山地壳缩短由南向北、由西向东逐渐递减的规律。通过GPS复测资料进行区域水平运动状态的分析,通过剪应变,面膨胀值的分布,可以发现挤压、隆升、拉张、沉陷过程中产生了正负转换的地带,在这些正负交界并且剪应变值增大的地区,一般都是地震多发区。

| Abstract: | Using observation results of crustal movement observation network of China in Xingjian,recent crustal movement of Tianshan and its adjacent area were studied in this paper.They obtained average deformation rate of Tianshan and put forward decline law of Tianshan crustal from north to south,west to east.Through analyzing regional crustal horizontal movement with GPS repetition measurement and shear strain、surface expansion distribution,they found positive and negative conversion zone in the extrusion uplift of extensional subsidence process and earthquakes usually occurred in such area with increasing shear strain. |
