| Abstract: | 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. |
| |
| Keywords: | environmental spatial analysis spatial structure analysis simulated data sets sampling designs. |
