基于GIS的地下水水源地补给潜力探讨

Discuss on the potential of groundwater recharge based on GIS

本文提出了一种基于GIS的补给潜力分析方法。在实例研究中,通过对地形、地表物质组成、包气带岩性、植被覆盖等因子建立的专题图层的叠加分析,确定了地下水的补给潜力分区,结合研究区含水层分布特征,综合确定了水源地的靶区和开采潜力区。研究表明,利用GIS确定研究区降雨入渗补给量是一种高效、直观、可行的方法。

Based on GIS, a method to determine water resource field target is presented. In case study, the recharge potential map was obtained by overlay analysis of main factors on groundwater recharge, such as topography, materials of land surface, zone of aeration soil permeability, and land cover, and then a water resource field target was selected. The result shows that GIS is a powerful, direct, and feasible method for water resource field planning, and has a capacious application prospect for water resources research.
