华北地区大范围精密水准和GPS垂直运动分析

Vertical Motion Analysis of North China Using Large Area Precision Leveling and GPS Data

  • 摘要: 利用华北地区2005-2007年大面积水准观测数据和1999年以来364个GPS测站(包括流动站和连续站)观测数据,分别获取其速度场。结果表明,该地区大面积水准和GPS重叠地区的垂直运动趋势基本一致,大致以太行山构造带为界,西部地区以隆升运动为主,东部地区以下沉运动为主,个别地区大面积水准和GPS的差异性运动可能是由于观测资料的时间跨度不一致和测点分布不尽相同所致。

     

    Abstract: Using large area precision leveling data of 2005-2007 and GPS data of 364 observation stations since 1999(including mobile stations and fixed stations), the velocity field of North China is calculated respectively. The results show that the vertical motion trend of large area leveling and GPS's overlapping areas are basically the same. With Taihang Mountain tectonic zone roughly as boundary, the western region is mainly in uplifting motion while the eastern region is mainly in sinking motion. Some areas' large area leveling and GPS's vertical motion are different, may due to the time span of data inconsistencies and measuring points distribution.
