| Abstract: | The spatial distribution of 8 trace elements in agricultural soils with sewage irrigation at the eastern suburb of Beijing were studied by variogram analysis. The spatial variations of these elements are much more significant in comparison with those from clean water irrigated soils. This is because of the accumulation of trace elements near the irrigation inlets. The contents of all elements show similar spatial structures. |
