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。
In view of the contradiction between supply and demand of water resources in the Yellow River Delta region, this paper evaluates the potential of shallow groundwater development. Mainly considering five influencing factors of groundwater recharge, aquifer characteristics, groundwater quality, groundwater exploitation intensity and land use, the paper establishes the basic data layer, using the evaluation model of weighted summation and spatial superposition function of GIS to weight five influencing factors Calculation and spatial data overlay calculation, draw the potential level and distribution of shallow groundwater development in this area. Divided into five levels, that is, the most potential areas for development, development potential area, more potential area, the basic potential area and no potential area.
