Spectrum Characteristics and Transfer Function of the Hydrograph of the Deep Aqueous System

The fluctuation of most of the hydrograph in the deep aqueous system records the fluid pulsation in lithosphere and variation of the earth's crust. Many observations have verified that groundwater is an ideal information carrier of the crust. In this paper, the series of input (precipitation, air pressure, Earth tide etc.) and output (water level, artesian flow) of the deep aqueous system are studied by using the spectrum analysis and system theory. The application concepts of transfer function and the spectral structure of the hydrograph enrich the knowledge of the deep aqueous system. Two typical spectral structures of the hydrograph of the deep aqueous system are obtained by comparing with many water-bearing systems of the Jizhong depression. One is from well Ma-17 and the other is from the well Xinze-5. Finally, the physical models of forming the spectrum of the hydrograph are constructed on the basis of the spectrum research on the deep aqueous system.

深部含水系统水文过程线谱特征及其传递函数

深部含水系统水文过程线的波动在很大程度上记录了岩石圈的流脉动及一些地质过程的定向变化。大量实践已经证明,地下水是地壳十分重要的信息载体。本文利用频谱分析和系统理论方法,剖析了两深部含水系统水位动态的形成,揭示了深部不同含水系统水位(或流)过程线与当地降水序列、气压及固体潮序列有密切关系的谱结构与特征。在水文地质领域引入传递函数,并提出了两类谱的结构模式。
