摘　　要：在对降雨量等值面生成方法研究的基础上,对比了径向基函数法、反距离权重法和克里金法等常用的空间数据内插方法。根据降雨量监测站的观测数据,比较3种方法的降雨量等值面图和均方根值,克里金插值法方法得出的均方根值最小,插值效果较好。利用普通克里金插值法得出的等值面图不仅考虑了数据的空间相关性,而且生成的曲面较为真实,能较好的反映降雨趋势。on rainfall isosurface generation method based on the study of Radial Basis Function, Inverse Distance Weighting method and Kriging interpolation method commonly used spatial data interpolation method. According to the observation data of rainfall stations, compare three methods of rain contour map and the root mean square value, Kriging interpolation method that the root mean square value of the minimum, interpolation effect is good. Ordinary Kriging interpolation method using gold out of the interpolation isosurface map not only considers the spatial correlation of data, and generating surface more real, can better reflect the trend of rainfall.
