摘　　要：西部地下水资源勘查不再是单纯的地理、地质和水文方面的问题．由于地下水的深赋存性质，决定了西部地下水的勘查与油气勘探一样，是深层的地球物理问题．地下水研究所涉及的基础地质问题、地层的含水性问题和水质问题是目前地下水水文地质研究的关键．这三个问题的有效解决，必须依靠勘探地球物理方法技术的有效运用和新方法、新技术的研究开发．本文在阐述地下水水文地质研究现状和面临问题的同时，就目前地球物理勘探技术的发展水平和在西部的发展状况，以鄂尔多斯盆地地下水勘查为例，提出了利用已有物探资料为地下水勘查服务的地球物理解决方案，从理论方法上证明其可行性，并提出了建立示范区研究的必要性，以期对目前正兴起的西部水资源研究提供参考．The study of the water resource is mainly the underground water exploration in the western of China. The evaluation of western underground water resource can not be reached by the application of geography, geology and geological hydrology only because the depth of underground water runs from 300 meters to 1500 meters. The exploration of underground water in the west is just like the exploration of oil and gas, which must be completed with the geophysical techniques. The exploration of under- ground water includes three key problems: basic geological structure and sediment (we call it as basic geological problem), whether there are water in the sub - stratum, and the water quality. All these problems need the help of geophysical methods and techniques, in which some new methods and tech- niques waiting for development and study. At the basis of the upper introduction, we provide some geophysical solution to the exploration of underground water in ARDOS Basin, prove the reliability of the application of petroleum geophysical data to the underground water prospecting, and conclude the importance of the case study and demonstration area. Hope this paper can lead a better mad to the underground water exploration in the west of China.
