Abstract: Thermal treatment is one of the hot technologies in the field of contaminated site remediation due to the advantages of good treatment efficiency and short construction period, therefore, it is of great significance to clarify the comprehensive impacts of thermal treatment on the soil properties and ecological functions for the assessment the soil values after treatment. Based on the analysis of a large number of relevant research and application cases, the impacts of thermal treatment remediation technology on the physical and chemical properties like soil organic matter, pH, nutrient components, together with the ecological effects on soil microorganisms, soil animals and plants exposed to the treated soil were summarized. The effects of thermal treatment process on the soil contaminant derivatives and the remediation efficiency for combined pollution were analyzed. Finally, the comprehensive effect of thermal treatment on soil and its guiding significance for practical remediation engineering were discussed. The key research focuses and directions of thermal treatment in the field application in the future were analyzed.
