| 摘 要： | 选取广西“十五”地震前兆网络项目地下水位数字化观测与模拟观测资料，利用固体潮形态、水震波、相关性、内在质量等方法进行了对比分析，结果表明：两种观测的动态变化基本一致；在仪器正常运行、无故障情况下，两者数据的相关性良好。综合分析认为数字化观测的信息量大，灵敏度高，跟踪速度等明显优于模拟观测。随着仪器稳定性能的提高，用数字化水位观测仪器取代模拟水位观测仪器是可行的。

| Abstract: | In this paper, the digital and analogue data of groundwater level in Guangxi are compared and analyzed from the aspects of solid tide, seismic water level fluctuation, correlation and inherence quality. The results show that their dynamic variations are similar and a good correlation is found between parallel observations using digital and analogue instruments when the instruments operate well and no failure occurs （the correlation coefficient of Ping-1 well at Tiandong is from 0.719 to 0.886 and that of Xishan well at Gulping is from 0.917 to 0.995） . Generally the digital observation contains more messages and its sensitivity is better than the analogue observation. With the improvement of instrument performance, it is feasible to use the digital groundwater level instrument to replace the analogue instrument. |
