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．
Western groundwater resources survey is no longer a simple geographical, geological and hydrological issues. Due to the deep nature of groundwater, the exploration of groundwater in the western part of the world, like that of oil and gas exploration, is a deep geophysical problem. The basic geological problems involved in the groundwater research, the water-bearing formation and the water quality are the key issues in the current hydrogeological research of groundwater. The effective solution to these three problems must depend on the effective application of exploration geophysical methods and the research and development of new methods and technologies. In this paper, the current situation and problems of groundwater hydrogeology research are elaborated. At the same time, taking the development of geophysical prospecting technology and the development in the west as an example, taking the exploration of groundwater in Erdos basin as an example, the paper proposes to use the existing geophysical data for groundwater exploration Geophysical solutions to prove its feasibility theoretically and methodically, and put forward the necessity of establishing demonstration area research in order to provide reference for the western water resources research that is currently emerging.
