摘　　要：为解决辽西地区干旱缺水问题,通过卫星遥感与地面物探相结合的工作方式,研究了水文地质信息提取方法及其应用技术,并在辽西地区开展了初步应用。结果表明,卫星遥感技术不仅可以从宏观上掌握研究区地下水赋存规律,还可探测到常规方法难以发现的水文地质信息,通过卫星遥感技术可以缩小地面物探工作区的范围,该方法有效提高了地下水探测的工作效率及其准确性。此外,通过对电测深电阻率值的定量分析表明,当探测到的九佛堂组岩组电阻率介于18～22Ω·m之间时,该处富水的可能性极大,该方法可有效降低在九佛堂组中物探找水工作的难度。In order to solve the problem of drought and water shortage in Western Liaoning,the hydrogeological information extraction method and its application technology were studied by combining satellite remote sensing with ground geophysical prospecting,and the preliminary application was carried out in western Liaoning. The results show that the satellite remote sensing technology can not only grasp the groundwater occurrence law in the study area macroscopically,but also detect the hydrogeological information which is difficult to obtain by conventional methods. Moreover,satellite remote sensing technology can narrow the ground geophysical exploration working area,making groundwater detection more efficient and accurate. In addition,the quantitative analysis of electrical sounding resistivity shows that the resistivity in Jiufotang Formation is between 18 and 22Ω·m,indicating high possibility of a water-rich formation. Therefore this method can effectively reduce the difficulty of detecting underground water in Jiufotang Formation.
