【摘要】 针对黄河三角洲地区水资源供需矛盾,该文对其浅层地下水开发潜力进行了评价。主要考虑地下水补给、含水层特性、地下水水质、地下水开采强度和土地利用五个影响因素,分别建立基础数据层,运用加权求和的评价模型和GIS的空间叠加功能,对五个影响因素进行加权计算和空间数据的叠加计算,得出该区浅层地下水开发潜力等级及分布图形。分为5个等级,即最有开发潜力区、有开发潜力区、较有潜力区、基本无潜力区和无潜力区。更多还原

【Abstract】 To rationally exploit the shallow groundwater in the Yellow River delta and alleviate the imbalance between supplying and demanding for water-resource,the article assessed the exploitation potential of groundwater. Mainly consideration in groundwater recharge, aquifer properties, groundwater quality, groundwater exploitation intensity and land use, the authors set up the basic data respectively. Then using weighted summation assessment model and space superposition function of GIS, they adopted weighted calculation on five influencing factors above and superimposed calculation on space data, and obtained a clear map of exploitation potential districts of shallow groundwater. As a result, the area was divided into five grade districts: the most own potential, own potential, relative own potential, general absence potential and absence potential.更多还原
