| 摘 要： | 对南口，大灰厂水平形变监测网的全部观测资料进行了处理和分析。结果表明：在１９８８－１９８９年期间，该区构造活动速率较大；１９８９－１９９２年虽然运动趋势没有明显的改变，但断裂活动平缓。这一活动过程可能与大同地震有关。该区整体运动性质以滑脱伸展为主，力学性质为张拉笥，与地质构造活动特征相吻合。表明了所建的水平形变测网具有一定的监测能力。

| Abstract: | In the paper, all the horiznotal deformation data from Nankou and Dahuichang areas are analysed and the results show that the tectonic movement of the areas was stronger during 1988 - 1989 and that although the change of the trend of the movement was less, the rate was obviously lowre from 1989 to 1991. This process of the movement is possibly related to Datong earthquake (1989). The movement of the fault blocks in the areas mainly showed the movement property of detachment and spread. |
