| 摘 要： | 分析了玉田井 1983年以来水位多年动态及年变动态规律特征,利用不同时段的降雨资料与该井水位年极值及水位升降幅度进行相关分析。结果表明: 水位多年动态及年变动态基本受降雨控制; 个别年份与降雨不匹配,而且这些年份多有中强地震发生。因此, 当水位长趋势变化与降雨不匹配, 1年尺度的年变规律发生变异时,其水位动态具有前兆意义。

| Abstract: | In this paper, the law of many years and annual variation dynamic characteristics of the groundwater level in Yutian well since 1983 are analyzed. Using the rainfall of different time interval, correlation analysis on the rainfall data and the annual extreme value and rise or fall ex tent of the groundwater level is made. The result show s that the groundwater level state was basically controlled by rainfall, it doesn't match the rainfall in some years, when the moderately strong earthquake occurred. Therefore it i s of precursory significance, when it doesn't match the secular variation and rainfall, the law will be changed for annual-variation of a year dimension in groundwater level state. |
