摘　　要：以西安某大型水库为例,介绍了水质数据的规范化处理过程及如何利用Surfer软件绘制湖泊水库垂向水质变化三维等值线图的方法。结果表明,以相对高程为基准对无效插值数据空白化处理能很好反映实际水位及水质变化,得到的三维等值线图既简单又直观的反映了实际水体水位、水质变化问题,结果真实准确,为科技论文的撰写投稿、湖泊水库的运行、管理与决策提供依据和支撑。Taking a reservoir in Xi'an for example,this paper introduces standardized treatment processes of water quality data and how to use Surfer software to draw three-dimensional contour map of vertical water quality change in lakes and reservoirs.The results show that relative elevation selected as the benchmark for blanking invalid data area can reflect the actual water level and water quality,and the three-dimensional contour map is simple and can directly reflect the actual water leve land water quality change,with accurate results,which can provide a scientific and theoretical basis for thesis writing and submission,as well as the operation,management and decision of lakes and reservoirs.
