摘要
本文应用灰色系统理论的ＧＭ模型对地下水动态资料进行了异常识别，发现在１９８１年河北宁晋ＭＳ５．８级地震、１９８３年荷泽ＭＳ５．９级地震、１９８５年河北任县ＭＳ５．０级地震前，有明显的异常显示，通过选择不同建模数据个数及外推个数，发现对豫０１井五日均值资料建模处理，选择２个月的数据１０天滑动逐次建模识别的异常较清楚。同时对所建模型的精度进行了分析，证明该方法在本区豫０１井、鲁０５井资料处理及前兆异常识别中有一定的应用价值。
Grey system GM model is used to distinguish anomalies of underground water.It is found that there were clear anomalies before earthquakes of Hebei Ningjin M=5.8 in 1981,Shandong Heze M=5.9 in 1983,and Hebei Renxian M=5.0 in 1985.It is also discovered that the anomalies are more clear in modeling of well Yu No.1 through selecting different modeling data.At the same time we have analysed the precision of different modelings which shows certain values for distinguishing anomalies in wells Yu No.1 and Lu No.5.
