摘　　要：以多角度评价地下水资源当前现状为目的,对水资源水文地质图数据采集及地下水资源评价方法进行研究。该方法使用GIS系统结合无人机搭载相机方式获取水资源水文地质图像,经过大气辐射误差校正、图像去噪和图数据融合处理后,获取水资源水文地质图数据,构建地下水资源评价指标体系;使用层次分析方法和GIS空间叠加分析方法构建地下水资源评价模型,以各评价指标为模型输入,输出地下水资源评价等级。最后以河南省为研究对象进行实验,实验结果表明,该方法可快速绘制高精度水资源水文地质图,可从多个方面对水资源使用功能进行评价,效果较好,能够为水资源合理规划利用提供有效的技术方法。In order to evaluate the current situation of groundwater resources from multiple aspects,this paper studies the data collection of hydrogeological map of water resources and the evaluation method of groundwater resources.This method uses GIS system and unmanned aerial vehicle(UAV)to acquire hydrogeological image of water resources.After atmospheric radiation error correction,image denoising and image data fusion,the hydrogeological map data of water resources are obtained and the groundwater resources evaluation index system is established.The evaluation model of groundwater resources is constructed by using the analytic hierarchy process and GIS spatial overlay analysis method,and the evaluation grade of groundwater resources is output with each evaluation index as the model input.Finally,Henan Province is taken as the research object,the experimental result shows that this method can quickly draw high-precision hydrogeological map of water resources,and can evaluate the use function of water resources from multiple aspects with a good result.It can provide an effective technical method for the rational planning and utilization of water resources.
