为提高应用地球物理方法划分含水层的准确性，提出将音频大地电磁法与核磁共振法结合运用的综合方法。运用该方法在内蒙古巴彦宝力格盆地某区开展野外试验，并将试验结果与该区域供水水文地质详查报告中的水文地质剖面图进行了比对。结果表明：①试验区100m深度范围内，该方法所揭示的含水层深度、厚度分布与水文地质剖面图基本一致；②据该方法，介质岩性为泥岩、粉质黏土、粉土、气孔状玄武岩和砂砾时，其衰减时间分别为≤30、30～60、60～120、120～260和260～600ms，据此得到的介质岩性分布与水文地质剖面图高度吻合；③该方法得到的含水层含水量变化与水文地质剖面图的涌水量变化规律一致。因此，运用该方法划分含水层具有很强的可行性，在生产实践中具有推广价值。

The accuracy of geophysical prospecting methods was limited .A combination of the audio magnetotelluric method and the nuclear magnetic resonance method was applied to aquifer division , enhancing the accuracy .Series of field tests for this method were carried out in an area of Bayanbaolige basin ,Inner Mongolia ,and the test results were compared with the hydrogeological profiles of the detailed hydrogeological survey for this tested area .The main conclusions were as follows :①The tested aquifer depth and thickness ,within the depth of 100 m ,were almost consistent with the hydrogeological profiles .②Based on this method ,the decay times for mudstone ,silty clay ,silt ,vesicular basalt and gravel were considered to be ≤30 ,30 60 ,60 120 ,120 260 and 260 600 ms ,respectively .This was highly consistent with the hydrogeological profiles .③The law of variation for aquifer water content was identical with that for water inflow represented in the hydrogeological profiles .Therefore ,this method was feasible ,and worthy to be promoted in production practices .
