德州深层地下水位漏斗形成主导因素识别与可恢复性研究

Identification and Restorable Research for the Major Factor of Deep Groundwater Depression Funnel in Dezhou

本文以近40年来的深层地下水开采和水位动态监测系列数据为基础,应用水文地质学、地下水动力学和统计学方法,揭示了德州深层水位降落漏斗形成和演变规律,识别和确定深层水位降落漏斗形成与变化的主导因素为人工开采;建立了德州深层水位降深漏斗变化与人类开采活动的相关模型为多次项模型,并预测了不同开采条件下德州深层水位降深漏斗中心和漏斗区平均水位的变化趋势,为制定漏斗合理调控奠定了坚实基础。

Based on the series data of deep ground water exploitation and dynamic groundwater monitoring in recent 40 years, using hydro-geology, groundwater dynamics and geo-statistical methods, the paper revealed the formation and evolution rule of deep groundwater depression funnel in Dezhou, identified and determined that the dominant factor to form the ground water depression funnel was artificial exploitation. The thesis established the model revealing relation- ship between variation of deep groundwater depression funnel with artificial exploitation and pre- dicted the change trend of water table in central depression funnel and mean water table under dif- ferent exploitation condition. The results can provide a solid foundation for making reasonable countermeasures of deep groundwater depression funnel in Dezhou.
