摘　　要：以滨州市境内所有气象观测站2016年采集的降水数据资料为基础,分别采用六种常见的空间内插方法进行系统的分析,并比较了这几种内插方法结果之间的差异,结果表明:克里金插值法在滨州市区域站降水量资料插值处理上应用性最优,其估计值在平均值、最大值、最小值上非常接近原始值,在标准差上也比较接近原始值,可以作为滨州市缺测站或疑误数据站的质量控制提供依据。Based on the precipitation data collected by all meteorological observatories in Binzhou in 2016,the paper systematically analyzed the 6 common spatial interpolation methods and compared the differences between the results of them.The results show that Kriging Method has the best applicability in the interpolation processing of precipitation data at Binzhou regional station.Its estimated values almost equal to the original values in average,maximum and minimum,and the standard deviation is also close to the original values,which can be used as a basis for quality control of Binzhou missing stations or mistaken data stations.
