摘　　要：为解决小尺度区域、缺水地区岛屿的浅层地下水富集性评估的相关问题,以岛屿为例,提出以GF-1与DEM等数据为数据源,选取岩性,地貌,坡度,植被覆盖度,地表温度,水域密度和土壤湿度,共7个指标进行提取,构建了该地区浅层地下水富集性遥感评估模型,得出了浅层地下水富集性等级图5级,并通过实测井中或泉水的水量对结果进行了验证。结果表明,评估结果满足误差精度要求,该方法能够对小尺度岛屿地区进行浅层地下水富集性评估。In order to solve the related problems about assessment of shallow groundwater potential in small scale areas and arid bedrock island areas, we take the Island in the Pearl River estual-y- as an example. The CF-1 data, DEM data and others are used as data sourees. Lithology index, relief index, slope index, vegetation-fraction index, land-temperature index, water-density index, soil-humility index are used as extraction indexes. A remote sensing model of shallow groundwater potential is constructed. The results of 5- level charts of assessment of shallow groundwater potential are obtained. The results are verified according to the water yield of the wells and the discharge of the springs. The results show that the assessment results can meet the requirements of error precision. This method can be used to assess shallow groundwater potential in small scale islands.
