摘要
基于地理信息系统的网格划分,在泰森多边形法的基础上利用自然邻点法内插出相关研究区每个网格上的雨量值,进一步做出降雨空间分布曲线,得出不同量级降雨量在研究区域的覆盖范围,为面雨量和降雨空间分布计算提供了新方法。
Based on the grid division of geographic information system(GIS),the rainfall amounts in all the grids of the relevant study area are interpolated with the natural neighbor interpolation on the basis of Thiessen polygon method,and furthermore,the spatial distribution curve of rainfall is plotted;from which the different magnitudes of rainfall amounts within the coverage of the study area are obtained,and then a new method is provided for the calculations of rainfall amount and rainfall spatial distribution as well.
