摘要
利用对高程数据的数学变换建立了包含１００００ 个数据点的模拟土壤微量元素含量基线值大型数据集，并在此基础上进行污染模型叠加产生污染影响大型数据集⒚以之为基础进行模拟采样。
Large data sets of baseline trace metal contents in soil,each composed of 10000 spots,were simulated by mathematical transformation with elevation data.Pollution models were added to these data to simulate pollution data sets.Based on these data sets,different sampling designs were conducted and their efficiencies in interpreting spatial continuity were studied.By comparison of the sample semi variograms,characteristics and influences on spatial analysis of each sampling design were discovered.
