音频大地电磁法在地下水质评价中的应用

摘要

The audio magnetotelluric method has been widely used in the field of groundwater exploration both in China and abroad.In this paper,the groundwater exploration in a certain area of Northwest China was taken as an example.The theoretical basis of the meth-od was elaborated and its application effect was discussed.As the equipment of audio magnetotelluric method is relatively light in weight,the exploration depth is relatively large,and hence the results are fairly satisfactory.Therefore this technology has a broad ap-plication prospect in groundwater exploration.%以西北某区的地下水勘查为例，对音频大地电磁法的野外工作方法技术作了较详细的介绍，并对其应用效果进行分析。音频大地电磁法因其装备相对轻便，勘探深度相对较大，应用效果良好，在地下水勘查中有着广泛的应用前景。
