摘    要:利用小波变换和多尺度分析原理,对周至井、三原井7年的水位日均值序列进行了分析,将周至井、三原井水位资料中的不同周期成分进行了有效分离,小波变换分解结果能够更直观和显著地反映地震活动,特别是印尼8.7级、汶川8.0级特大地震及其中强余震异常显示明显。对甘东南地区的5级以上地震也有较明显的前兆反映,表明小渡分析在处理和分析水位资料方面是一种有效的方法。

关 键 词:小波分析  井水位  多尺度分析  前兆异常

Abstract:The daily mean value sequences of seven years lyzed by the converted wavelet and multi - scales method, period of Zhouzhi well and Sanyuan Well were anathe different periods of the data were separated , and the results showed that the converted wavelet can reflect the seismicity obviously, especially in Indonesia Ms 8.7 earthquake and Wenehuan Ms 8.0 earthquake and their aftershocks. It also can obviously reflect the precursors of earthquakes with Ms≥5.0 in south of Gansu province, and this is a valuable method in well level data analysis.
Keywords:Wavelet analysis  Well level  Multi-scales analysis  Precursory anomaly
