Abstract: Due to the long-term residence and accumulation in environment, soil heavy metals had many realistic and potential risks to the ecological environment and human health, being come under more and more attentions. To evaluate the soil heavy metals contamination degree is of significance to the environmental and human health issues, which needs a kind of or several kinds of correct evaluation methods. This paper summarized several related evaluation methods commonly adopted at home and abroad, including index method, model index method, speciation analysis- based method, quantitative analysis of available and total heavy metals contents, human health risk assessment method, and GIS and geostatistics-based method. The index method mainly includes Nemerow index method, enrichment factor method, geo-accumulation index method, and potential ecological hazard index method; and the model index method mainly includes fuzzy mathematics model, grey clustering model, and analytic hierarchy process, etc. The advantages, disadvantages, and limitations of the related methods were also discussed.
