Based on fuzzy mathematics comprehensive evaluation, the toxicity of heavy metals was taken into account. The fuzzy comprehensive evaluation results by pollutant concentration exceeding standard weighting method, toxic response coefficient heck-stepping index weighting method and heavy metal toxicity sorting weighting method were compared with the potential ecological risk evaluation results. The research results showed that the evaluation results by toxic response coefficient back-stepping index weighting method could reflect the actual results more truly and accurately.
