摘　　要：分析了8种典型的土壤热修复技术的修复效果和成本;从可持续化修复的角度出发,探讨了热修复技术对土壤pH,有机质组成、矿物结构、生物结构等造成的不同程度的影响;探究了热修复后土壤的再利用途径。Soil remediation has become a hotspot in China.There are many researches on soil thermal remediation but litle attention has been paid to the change of soil property during thermal remediation.This paper compares eight typieal soil thermal repair techmologies and analyzes each thermal repair technology in terms of target pollutants and costs.Then,from the perspective of sustainable repair,it discusses innovative thermal repair technology.Efiects on soil properties such as soil pH,organic matter,mineral structure,biological structure,vegetation,secondary pollution,elc.are analyzed,Next an in-depth approach to soil reuse after thermal repair is explored.In the end,suggestions are given to the thermal repair technologies and soil reuse after remediation so as to provide a certain theoretical basis for sustainable applieation of thermal repair technology.
