| 摘 要： | 结合中国西部区域的数字高程数据以及地壳垂直运动速率数据，计算中国西部地区地壳垂直运动引起的重力场变化的分布，并与卫星重力观测结果进行对比。研究表明：中国西部区域的重力场变化与地壳垂直运动速率场变化有很强的相关性，青藏高原以南的喜马拉雅山脉地壳上升运动速率最大，其引起的重力变化为正的最大值；准噶尔盆地地壳下沉运动速率最大，其引起的重力变化为负的最大值；塔里木盆地及柴达木盆地地壳下沉运动速率相对较小，相应地引起的重力变化值相对较小。

| Abstract: | The relation between vertical crustal movement and the gravity change was considered and simulated.The gravity change was calculated with the digital elevation data and the velocity of vertical motion in the western China,was compared with the gravity change of the satellite observations.Results indicate that the characteristics of gravity change is highly relevant with the velocity of vertical motion.The Himalaya Mountain has the greatest positive value of gravity change in the south of the Qinghai-Tibet P... |
