摘要

针对雨量站点及等雨量线的特征

讨论了一种新的等雨量线追踪途径。该方法首先用二次曲面对不规则站点雨量进行格网化

然后在格网上对等雨量点进行判断、追踪以及在追踪过程中如何消除追踪的二义性。最后对开曲等雨量线和闭曲等雨量线的起点、终点进行了判断。结果表明该方法提高了绘制等雨量线的质量

对于计算流域的面雨量具有重要实际意义。

Abstract

A new method of tracing precipitation isoline is introduced in term of the character of rain spot and iso-line. The method

firstly

grids the precipitation amount by conicoid

then judges and traces isoline and brings forward a way of how to avoid connection uncertainty of isoline. Lastly

jumping-off and end point of opening-curve

and close isoline were judged. The method improves the precision of the precipitation isoline and is important to count the surface precipitation of the drainage area.
