| 摘 要： | 分析了降雨空间分布的影响要素及降雨空间插值的主要方法,并在此基础上,利用地理信息系统(GIS)的空间分析功能,综合考虑高程、坡度、坡向等影响降雨空间分布的多种要素,应用协克里金方法,探讨流域降雨量的空间插值问题及其应用,并与反距离权重法、克里金方法等单要素方法进行了降雨空间插值的效果比较.结果表明:应用协克里金方法,在综合考虑高程、坡度、坡向等影响要素的条件下,对降雨进行空间插值,其结果具有比较好的精度.

| Abstract: | The factors influencing the spatial distribution of rainfall and main methods of rainfall spatial interpolation were analyzed.Then with a comprehensive consideration of the influences of elevation,slope and aspect,the problem of spatial interpolation and application of rainfall interpolation calculation for the Meijiang River Basin were discussed by the spatial analysing function of GIS.With the reverse distance weighted method,the ordinary Kriging method and the new Co-Kriging method which take the influences of elevation,slope and aspect information into account,the comparison was made on several rainfall spatial interpolation methods with ArcGIS.The study shows that Co-Kriging method is obviously superior to the other two methods. |

| Keywords: | GIS spatial interpolation Co-kriging inverse distance weighing |
