摘　　要：为了将GPS水汽资料以图形化方式展示给用户,在简要介绍GPS水汽反演原理和综述Surfer软件绘制等值线的应用场合的基础上,以福建GPS水汽监测系统为背景将Surfer软件引入GPS水汽资料应用中。通过设计GPS水汽等值线分布图生成系统描述了C#调用Surfer自动绘制GPS水汽等值线分布图的过程。结果表明该系统生成的等值线分布图能够实时有效的反映福建上空水汽含量的分布及变化情况,可以为相关气象预报提供参考依据。In order to graphically display GPS water vapor data to the user,after introducing inversion of GPS water vapor principle in the brief and reviewing Surfer applications in drawing contours,this paper imported surfer to the application of GPS water vapor data in the background of Fujian GPS water vapor monitoring system.Through designing GPS water vapor contour production system displayed the process of drawing GPS water vapor contour automatically by C# called Surfer.The results indicate that the contour produced by the system can effectively reflect the distribution of water vapor content and changes over Fujian and provide a reference to the related weather forecasting.
