| 中文摘要 | 为了减少非平稳区域化变量的插值计算的工作量,以中国中东部地区59站1960~2000年的年平均降水量为数据源,采用普通克立格法与泛克立格法两种方法对降雨量进行空间插值,对其插值结果进行比较。结果表明,两者的插值结果非常相似,且前者的插值精度略优于后者。认为在无需详细了解变量的空间变异性情况,而只进行空间插值研究时,用普通克立格法代替泛克立格法进行非平稳区域化变量的空间插值具有计算简单、无需确定漂移等优点,同时可以取得较好的插值效果。; To reduce the workload of the spatial interpolation of nonstationary regionalized variables with the Kriging method,the ordinary Kriging and universal Kriging methods were used for spatial interpolation of data of average annual precipitation for 59 stations in the middle and east regions of China from 1960 to 2000.The results of interpolation of the two methods are close to each other,while the precision of the former is a little higher.As a conclusion,the ordinary Kriging method can be used for replacing the universal Kriging method for spatial interpolation of nonstationary variables if it is unnecessary to investigate the spatial variability of variables.Without need for determination of drifts,the ordinary Kriging method is simple in calculation,and the interpolation result is satisfactory. |
