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

地下水是我國重要的生產(chǎn)生活水源，，同時地下水也是礦山突水等地災(zāi)的主要因素.因而高精度探測地下水就成為地下水研究中首先要解決的問題.[1-3]傳統(tǒng)的電阻率法物探理論都基于三維的認(rèn)識：不同單元體的導(dǎo)電率是不同的，具體到地下水就是當(dāng)?shù)刭|(zhì)單元含有地下水后，其電導(dǎo)率即與含水飽和度、礦化度、地層孔隙度、滲透率等諸多因素相關(guān)，反映到電法物探方法上就是電導(dǎo)率的異常.低阻異�？赡苁呛�水體，當(dāng)然金屬礦床也可以出現(xiàn)低阻異常，第四紀(jì)地層也是普片的低阻異常帶.[4-10]這在探測地下水方面就會出現(xiàn)多解性.這也是地下水探測的難點(diǎn).其實(shí)在現(xiàn)有的物探領(lǐng)域有意義的地質(zhì)單元體不外乎分為固體和流體.流體主要是指地下水體.探測地下水是否還可以從地下水的“流性”上著手呢，這樣就可以在固體和流體上做一次具有極大意義的區(qū)分.地下水是由補(bǔ)給、徑流、排泄的動態(tài)水系網(wǎng)構(gòu)成.
