摘要
根据地下水过量开采的现状,结合每一个观测井所处的地质环境以及井区的水文地质条件、观测系统等因素,对超采地下水造成井水位非前兆异常特征的普遍性与个性进行研究。结果表明,这类非前兆异常与含水层状态密切相关,变化幅度大,空间上不集中,时间上不丛集,一般为单个变化,个性特征较明显。
Based on present situation of over exploited ground water as well as geological environment of each observation well and hydrogeology condition and observation system of well area, the general and individual characters of no- precursory well water level anomaly caused by over exploiting is studied. The results indicate that this kind of no- precursory anomaly is closely related to aquifer conditions; they are neither concentrated in space domain nor clustered in time domain and each has its own distinctive characters.
