摘要

North China Plain covers an area of 140,000km2. Because of groundwater overdraft for many years, the level is rapidlyrnfallen, shallow water-bearing bed seriously drained, and deep one appears many large-scale drawdown cones. The shortage ofrngroundwater resources cause a tense situation in urban, industry and agriculture water-supply. Under the situation, it is a urgent to usrnto investigate and evaluate the groundwater useful Potentials. The north part of Taihang Mountain front plain is chosen as a testrnregion using remote sensing technique. Landsat-7TM image and aerial colour infrared image are used in the work.. Through arncomprehensive analysis and study of satellite and aerial images and other related data, the following results are obtained. ①Thernalluvial and flood deposit fans are exactly delimitated. ②The spacial overlapping relations between different fans arerndefined.③Palaeochannels are interpreted in detail. ④Ten shallow-buried areas of groundwater and one groundwater discharge arerndiscovered. ⑤All surface sediment types and all kinds of microgeomorphic bodies are interpreted. ⑥6 rich groundwater areas arerndefinited, and two of all are confirmed by a geological examination.
