摘　　要：在地下水资源日趋缺乏的太行山前河北平原,采用遥感技术开展地下水资源调查评价。在充分利用卫星遥感(ETM+)图像数据反映地下水资源相关信息灵敏的基础上,综合其他常规资料,准确的圈定出山前冲洪积扇的范围,划分出它们的形成期次和扇体结构。明晰了不同河流扇体之间和同一河流不同期次扇体之间的空间交叠关系,恢复了主要河流的水流系统。详细解译出其他如古河道、地下水浅埋区、地下水溢出区、决口扇、消亡湖泊及其古三角洲等水文地质要素。在此基础上,推测出具有开采潜力的地下水富水区6处。在对其中的两处进一步开展详细的水文地质勘察后,被有关部门确认为极具开采潜力,可做为大型城市供水水源地。North China Plain covers an area of 140,000km2. Because of groundwater overpumped for many years, so its level is rapidly fallen. Shallow water-bearing bed seriously drained, and deep one appears many large-scale drawdown cones. The shortage of groundwater resources cause a tense situation in urban, industry and agriculture water-supply. Under this situation, it is a urgent to investigate and evaluate the groundwater useful potentials. The north part of Taihang Mountain front plain is chosen as a test region. Landsat-7TM image and aerial colour infrared image are used in the work. Through a comprehensive analysis and study of satellite and aerial images and other related data, the following results are obtained.①The alluvial and flood deposit fans are exactly delimitated. ②The spatial overlapping relations between different fans are defined. ③Palaeochannels are interpreted in detail. ④Ten shallowburied areas of groundwater and one groundwater discharge are discovered. ⑤All surface sediment types and all kinds of microgeomorphic bodies are interpreted. ⑥Six rich groundwater areas are definited, and two of them are confirmed by geological examination.
