Abstract: Urban industrial wasteland might have been affected by toxic and hazardous substances emitted by the original production activities. Consequently, pollution survey analysis and environmental risk assessment should have been conducted before redevelopment. In the paper, by surveying soil sample from waste dump, tailing pond and surrounding area in Lead-Zinc Mine, fuzzy mathematics method was adopted to establish Fuzzy Comprehensive Evaluation model as to analyze conditions of soil pollution by heavy metal and soil nutrient. It would provide important scientific basis for pollution control and ecological restoration in the mining area and thus carry out comprehensive ecological restoration in Lead-Zinc Mine. Fuzzy Comprehensive Evaluation results indicated that soil pollution by heavy metal were severe. It could give priority to develop forestry. Most deficient soil nutrient elements were available P and N. Due to the lack of nitrogen and phosphorus, it was necessary to improve the soil before phytoremediation.
