| 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，发现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。

| Abstract: | M_S5.9 earthquake occurred among Balinzuoqi and Alukeerqinqi in august 16 2003,this earthquake occurred in edge of 2003 year seism dange zone.In this paper on the basis of primary evidence of year danger zone and midyear track these precursory anomalies were analysed including Dadianzi Well ground water level,Kulun Well ground water level,Kailu water radon before M_S5.9 earthquake,the precursory anomalies around Inner Mongolia were analysed and studied at the same time.The results showed that there is a group of trend anomalies and medium-short term anomalies before this earthquake. |
