中文摘要：

基于巴东地区布格重力异常信息,采用艾黎-海斯卡宁均衡模型,计算了该区均衡重力异常。结果显示,该区均衡重力异常变化范围为-45×10^-5ms^-2-45×10^-5ms^-2,大部分区域基本处于重力均衡状态,局部存在弱正异常与弱负异常,弱正均衡异常呈条带状。研究表明,太行-武陵重力梯级带基本处于均衡状态,内部存在差异;巴东地区西北部存在一定程度的地壳均衡调整空间;巴东Ms5.1地震区域处于重力均衡状态,推测其发震与地壳均衡调整无直接关系。

英文摘要：

Isostatic gravity anomaly in Badong area was calculated using the Airy model. The results show that the isostatic gravity anomaly ranged from - 45 × 10^-5 ms^-2 to 45 × 10^-5 ms^-2, the most of the region was in the gravity isostatic state. Weak positive anomaly and weak negative anomaly appeaed in local areas, and weak positive isostatic anomaly presents in strip. The study shows that Taihang, Wuling gravity zone basically was in isostatic state with some differences in the internal. The northwestern in Badong area might occur isostatic adjustment. Badong Earthquake region was in the gravity isostatic state,that means the Badong Earthquake does not relate to the isostat- ic adjustment.
