摘  要:
以安徽省东至县为例,系统研究了反距离加权插值法、径向基插值法、全局多项式插值法、局部多项式插值法、普通克里格插值法、简单克里格插值法、泛克里格插值法和析取克里格插值法对区域土壤有机质空间变异评价准确性的影响。结果表明,普通克里格插值法优于其他插值方法,所以东至县土壤有机质的插值分析应使用普通克里格插值法。

摘  要:
With Dongzhi County in Anhui Province for example,the paper systematically studies several interpolation methods,including the inverse distance weighting method,radial basis functions interpolation,global polynomial interpolation method,local polynomial method,ordinary kriging interpolation method,simple kriging interpolation method,universal kriging interpolation method and disjunctive kriging interpolation method,as well as their impact on the accuracy of the evaluation on the spatial variation of regional soil organic matter.Results indicate that,ordinary kriging interpolation method is better than others,therefore,it should be applied to the interpolation analysis of the soil organic matter in Dongzhi County.
