| Abstract: | Integrating with Geographic Information System(GIS), the technical course of spatial data analysis
(SDA)for the assessment of urban soil pollution is brought forward. The data processing method, assessment
unit dividing, assessment index determination and the weight for each index are also discussed. With the module
of spatial extension of Arcview,a method for the assessment of urban soil by spatial data analysis is realized by
program. This method is applied in the assessment of soil pollution in Beijing. It proves that the spatial data
analysis is an effective method for the assessment of urban soil pollution in visual environment. |
