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。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.
