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。
The current crustal movement in Tianshan and its adjacent areas has been studied by using the results of the basic stations and regional stations in the “China Mainland Tectonic Environmental Monitoring Network” in Xinjiang, and the crustal movement rate of Tianshan Mountains has been obtained. It is proposed that the shortening of the Tianshan crustal from south to north, From west to east gradually diminishing law. Through the GPS retesting data to analyze the regional horizontal movement state, through the distribution of shear strain and surface swell value, it can be found that the zone of positive-negative transition during the extrusion, uplift, tension and subsidence can be found at these positive and negative boundaries And shear strain values increased area, are generally earthquake prone areas.
