摘要

分析了距张北-尚义Ms6.2地震震中110km范围内，内蒙古自治区前兆台网地下水位高值异常特征。利用水化前兆标志及判定方法探讨了水位高值异常与张北-尚义地震的关系，并对其判定指标进行了统一约定，分别用异常频次累加加速判别指标值和异常频次综合变化速率值二项指标对张北-尚义Ms6．2地震进行了中期、短期、短临尺度的检验性预测。张北-尚义Ms6．2地震的发震时间基本符合判断结果，指出地下水位高值异常是1998年1月10目张北-尚义Ms6．2地震的前兆反映。
In this paper, the authors analized the characteristics of high value anomalies of under-ground water level, which detected by the Inner Mongolia precursory monitoring network within the limit of 110 km apart from the epicenter of Zhangbei-Shangyi Ms6. 2 earthquake.By using hydrochemistry precursory mark and the judgement method , they also studied the relation between high value anomalies of water level and Zhangbei-Shangyi Ms6. 2 earthquake.The judgement scales have been appointed. By using two scales of anomaly frequency accumu-lation and changing velocity ratel the Zhangbei-Shangyi Ms6. 2 earthquake is tested for the medium- and short term forecast. The occurrence time of Zhangbei-Shangyi Ms6. 2 earth-quake accorded with the fundamental result of this paper and it should be pointed out that the anomalies are a precursory reflection for Zhangbei-Shangyi Ms6. 2 earthquake occurred on Jan-uary 10, 1998.
