| 摘 要： | 降水量等值线图的绘制除手工方法外,有多种计算机辅助方法及软件。在总结前人研究及实践的基础上,结合实际工作的需要,提出应用网格单元方法通过计算机辅助来完成等值线图的绘制,实现降水量等值线图绘制的客观化。该方法将流域分成若干有限个网格单元,应用流域内所有雨量站所在单元降水量及雨量站所在单元的位置,通过一定的数值计算方法计算所有单元的降水量,之后将大于等于某一数值所有网格单元区域的边界作为等值线,最终获得降水量等值线图。

| Abstract: | There are various computer-aided methods and softwares for drawing precipitation isolines, besides manual methods. We propose a new method complete drawing the precipitation isolines with grid method on computer. Comparing with the traditional method, it is more objective. We divided a watershed into a finite number of units. According to the precipitation value of all the precipitation stations and their location, we calculated all the units of precipitation with a certain numerical methods. Then, we used a certain numerical unit area boundaries as isolines. Finally, we completed drawing the precipitation isolines of the watershed. |
