Abstract：Accurate detection of groundwater is to look for water sources, such as mine water and water management an important factor. The conventional geophysical methods detect groundwater exist multiple solutions of the problem.

The fundamental reason is that conventional geophysical methods can not capture the groundwater recharge, runoff and discharge process occurs with the surrounding geological material at any time after the exchange was the forma-     -tion of magnetic fluid magnetic magnetic dynamic information. This study assumes that groundwater is flowing in the magnetic field homogeneity, On this basis, derived resistivity of water is negatively correlated with the time of the form- la. And to do this based on laboratory simulation speed of different solutions at different magnetic field measured by the change of resistivity. As a result, consistent with the formula. Ground mag-netic fluid on the Groundwater detect-
ion theory was constructed on this basis. It broke the only three- dimensional geophysical fields of information capture, and increase the time dimension of the groundwater capture of dynamic information. To some extent resolved detecti-      on of multiple solutions for groundwater issues

引言    

地下水是我国重要的生产生活水源，，同时地下水也是矿山突水等地灾的主要因素.因而高精度探测地下水就成为地下水研究中首先要解决的问题.[1-3]传统的电阻率法物探理论都基于三维的认识：不同单元体的导电率是不同的，具体到地下水就是当地质单元含有地下水后，其电导率即与含水饱和度、矿化度、地层孔隙度、渗透率等诸多因素相关，反映到电法物探方法上就是电导率的异常.低阻异常可能是含水体，当然金属矿床也可以出现低阻异常，第四纪地层也是普片的低阻异常带.[4-10]这在探测地下水方面就会出现多解性.这也是地下水探测的难点.其实在现有的物探领域有意义的地质单元体不外乎分为固体和流体.流体主要是指地下水体.探测地下水是否还可以从地下水的“流性”上着手呢，这样就可以在固体和流体上做一次具有极大意义的区分.地下水是由补给、径流、排泄的动态水系网构成.
