| 摘 要： | 利用首都圈地区的高精度高程数据,通过Airy均衡补偿模型计算出莫霍面的深度,进一步运用Parker公式计算出地壳所产生的重力异常值.然后从实际布格重力异常观测值中减去均衡校正值,得到该地区的均衡异常值.通过对首都圈地区的均衡重力异常进行分析,讨论了该地区的均衡状态.研究结果表明,首都圈大部分地区基本处于重力均衡状态,非...

| Abstract: | By using the elevation data and Airy model,the Moho depth can be calculated.Through applying Parker's formula,the isostasy gravity correction of the crustal deformation can be obtained as well.Therefore,the isostasy gravity anomalies gained by subtracting the corrections from observed Bouguer anomalies approximately represent the isostatic features of Chinese capital area,which plays an important role for investgating the deep structure and earthquake prediction in the future.The results show that the isost... |
