| 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, assessmentunit dividing, assessment index determination and the weight for each index are also discussed. With the moduleof spatial extension of Arcview,a method for the assessment of urban soil by spatial data analysis is realized byprogram. This method is applied in the assessment of soil pollution in Beijing. It proves that the spatial dataanalysis is an effective method for the assessment of urban soil pollution in visual environment. |
