| 摘 要： | 利用山东地区38个GNSS基准站2011～2016年连续6a的观测数据,对山东地区地壳垂向形变场特征进行系统分析。结果表明,山东地区地壳垂向形变具有明显的差异性,形变量最大的区域为山东西南部地区,形变速率约为-24.0mm/a;西北部地区形变速率较大,为-15.0mm/a;东南部以及沿海地区沉降速率较小,为-0.5～3.0mm/a;而在中部地区(泰山山脉)呈隆升趋势,形变速率为0.3～5.0mm/a。

| Abstract: | The vertical deformation field characteristics of the crust in Shandong area are systematically analyzed using observational data from 38 GNSS datum stations in 2011-2016. The results show that the vertical crustal deformation in Shandong area is significantly diverse. The southwestern part of Shandong area has the greatest deformation variables, where the rate of deformation is about -24.0 mm/a; the northwestern region is -15.0 mm/a. The settlement rate is small (-0.5－3.0 mm/a) in southeastern Shandong and the coastal areas. However, in the central part of Shandong area (Mount Tai Mountains) the rate of deformation is 0.3－5.0 mm/a, which shows the trend of uplift. |
