摘　　要：在利用地球物理方法探测西南岩溶山区地下水,确定宜井孔位时,正确分析、判断引起物探异常源的性质,选择合理的方法是决定能否获得地下水勘查成功的关键。通过分析在广西隆安县多处西南岩溶山区找水的成功实例,提出了适宜本地区的音频大地电场法、音频大地电磁测深法组合的物探找水模式,并对其勘查效果进行浅析,总结出确定宜井孔位时几点经验。供从事西南岩溶山区找水工作者参考。In the utilization of geophysical methods to detect underground water in karst mountain areas of Southwest China and the de- termination of suitable well position, the correct analysis and judgment of the properties of anomaly source and the choice of proper methods constitute the key to the successful exploration of underground water. Based on an analysis of the cases of successful water ex- ploration in quite a few karst mountain areas in Long＇an County of Guangxi, the authors put forward the geophysical water exploration model based on the combination of audio frequency telluric electric field method and audio frequency magnetotelluric sounding method, and made a tentative analysis of its exploration effect. Some experience concerning the determination of suitable well position was summed up as reference for water exploration workers in this region.
