摘要
剑川龙门机井水位变化呈现出在长周期升降背景下同时存在年变化的规律性,主要是受大气降水和旱涝趋势的制约。它的短期震兆异常是水位变化的“正向加速”现象。本交给出了异常判别指标及其效力检验。
The water level variation in Longmen pump-well, Jianchuan, features an annual variation regularity under a long-term rise-and-fall background, which is constrained by atmospheric rainfall, drought and flood. The short-term precursory anomaly is the 'positive acceleration' phenomenon of water level. The recognition criterion of water-level anomaly and its effect examination are presented in this paper.
