[目的]探讨克里格插值和高斯序贯模拟2种方法在土壤重金属污染分析中的差异，以期为土壤重金属污染分析方法的选择提供参考依据。[方法]以山东聊城某县重金属铜采样数据为研究对象，利用克里格插值和高斯序贯模拟2种方法进行土壤重金属铜的空间分布建模模拟。并选择30个采样点作为交叉验证数据集，对2种插值方法进行对比分析。[结果]克里格方法和高斯序贯模拟在均值段和极值段的模拟各有优势，研究者应根据试验数据的特点及应用目的对二者进行选择使用。[结论]土壤重金属污染分析是土壤治理、生态修复的前提，该研究结果对于根据不同目的需求来选择不同的插值、模拟方法具有重要意义。

[Objective] This study was to explore the difference of kriging interpolation and sequential Gaussian simulation on analyzing soil heavy metal pollution with a view to provide references for analyzing the heavy metal pollution of soil. [Method] The sampling data of soil copper from a county of Liaocheng, Shandong Province was set as the study objective. Kriging interpolation and sequential Gaussian simu- lation were used to simulate the spatial distribution of soil copper. And 30 sampling points were selected as the cross-validation data set to compare the two interpola- tion methods. [Result] Kriging method and Gaussian sequential simulation have their own advantages on simulating mean segment and extreme segment, therefore, re- searchers should choose the proper method based on the characteristics of test data and application purposes. [Conclusion] Analysis of soil heavy metal pollution is the prerequisite for soil management and ecological restoration. The result of this study is of important significance for choosing different interpolating and simulating methods to analyze soil heavy metal pollution based on different purposes.
