摘要

摘要: 为了研究近年来我国GNSS基准站地壳大气负荷垂向形变细部特征,使用格林函数积分及简化方法对中国大陆构造环境监测网络中的6个基准站共计36个月的大气负荷效应进行了计算和分析,结果表明,大气负荷是造成地壳非构造垂向形变的重要因素,大气负荷效应引起的地壳垂向形变量的区域性差异及垂向形变量在我国东北部和西部新疆地区为最大,大气负荷效应改正可使GPS垂向精度进一步提高。

Abstract: In order to study the vertical deformation detailing characteristics of the crustal atmospheric loading of GNSS station in China, the 36month atmospheric loading effect of six reference stations in the crustal movement observation network of China have been calculated and analyzed based on the Green function integral and simplification method. The results show that atmospheric loading is the important factor to cause the vertical deformation of the crust. The regional variation and vertical deformation in the earth's crust caused by atmospheric loading effect are the largest in northeastern China and western Xinjiang area. The correction of atmospheric loading effect can further improve the vertical accuracy of GPS.
