Abstract: The pollution assessment which can determine the quality of the soil provides reliable scientific evidence for pollution treatment. We took six kinds of heavy metal elements got from the soil of Tengzi Village, Xuanwu District, Nanjing City as evaluation factors. We used the principal component analysis, correlation coefficient analysis and grey relational analysis to make the determination. The stability of the evaluation results was compared by discrimination. Then we choose the more reliable result to carry on the spatial interpolation to produce the pollution situation thematic map. The results of the evaluation showed that the results based on GRA-TOPSIS were more reliable and the soil pollution was consistent with the actual situation. TOPSIS had a higher applicability in pollution assessment of soil heavy metal.
