| 摘 要： | 在ARCGIS支持下，将GIS空间数据管理功能和地质统计学的空间分析功能相结合，利用云南省30个典型县水稻灌溉用水定额数居，进行空间插值精度比较。交叉验证结果表明：地质统计学方法优于常规的距离反比法、径向基函数法、多项式插值方法；地质统计学方法中，普通克里金球状模型插值精度较高。

| Abstract: | ARCGIS was employed to combine the space data management in GIS with the space analysis in Geostatistics, and the precision of different interpolations based on the irrigation water qutoa of 30 typical counties in Yunnan was compared ; the results of cross validation indicate that the methods of Geostastistics are better than the conventional inverse distance weighting, the polynomial and the radial basis function; The precision of the Ordinary. Kriging spherical model was more precise than other methods of interploation in Geostastistics. |
