求面平均雨量的计算机实现方法

The Method of Realization to Seek the Areal Mean Rainfall by Computer

为了能够方便、快捷而准确地求出任意边界内的区域平均值,应用自主开发的基于GIS的等值线分析系统,以降水数据为例,给出了面平均值计算机算法中的网格法和等值线法的原理及实现步骤,并论述了它的快捷性、准确性,以及两种算法的优缺点和适用范围。

In order to calculate the regional average within the arbitrary boundary conveniently, quickly and accurately, there are the principle and implementation steps about the grids method and the Isolines method about calculating the areal average through computer in the paper , basing on GIS Isolines analysis system with the rainfall data as an example, and discussing its fast, accuracy, advantages or disadvantages and the application scope of the two algorithms. recipitation; the grids meth-
