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。

Lastly , jumping-off and end point of opening-curve , and close isoline were judged .

等雨量线的自动绘制方法

等雨量线绘制模块采用普通克里格插值方法，对雨量测站的降雨数据进行内插，并绘制等雨量线图。

By utilizing Kriging method , isoline drawing module could interpolate rainfall data , and draw isohyet chart .

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。

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