琼海加积井水位模拟观测与数字观测资料对比分析

Analysis on the comparison between the analogue and the digital observational data of water level at Jiaji Well in Qionghai

通过对琼海加积井数字水位与模拟水位的观测资料进行对比分析,发现其动态变化特征一致,与固体潮的相关系数也基本一致,数据的相关性及内在质量良好,映震能力相当。数字观测具有数据信息量大,传输速度快,人为误差小的优点,可以取代模拟水位观测。

By comparatively analyzing between the digital and the analogue records of water level at Jiaji Well in Qionghai. The result indicates that their dynamic variational characteristic are accordant with each other, the correlation coefficients with the solid tide are essentially iden- tical. The correlation between them and the inherent quality is very good. The ability of respond to the earthquake is also quite good. But the digital record is of many benefits, for example large amounts of information, the faster speed in transfer, and little of the human error. The digital record can substitute for the analogue record completely.
