摘　　要：2003年8月16日内蒙古巴林左旗-阿鲁科尔沁旗间发生5.9级地震。根据年度危险区的确定、前兆异常跟踪及其主要依据,分析了这次5.9级地震前大甸子井、库伦井地下水位、开鲁井水氡等前兆异常,在此基础上,对内蒙古附近区域的前兆异常也进行了分析和探讨,表明该次地震前在内蒙古及附近区域出现了一组中期、短期前兆异常及宏观异常,文中还研究了该区域前兆异常的演化过程。MS5. 9 earthquake occurred in Balinzuoqi and Alukeerqinqi region on August 16, 2003. This earthquake occurred at edge of 2003 year seismically risk zone. In this paper, on the basis of main evidence of the year risk zone and anomaly tracking, the authors analyzed the precursory anomalies including groundwater level of Dadianzi well and Kulun; water radon of Kailu well before MS5. 9 earthquake. At the same time, the authors also analyzed and studied the precursory anomalies around Inner Mongolia region. The result shows that there is a group of trend anomalies and medium-short term anomalies before this earthquake.
