Abstract: The objectives of contaminated soil remediation are to transfer and transform the hazardous contaminants in soil,to eliminate and reduce their toxicity,and to restore or partly restore the ecological service function of soil.Since soil contamination is always a combined one,it is essential to use multiple methods to remediate contaminated soil.It is a tendency of soil remediation to use a uniform method,which aims to restore the ecological service function of soil by combining the restoration of internal function with external clean function.This paper discussed the concepts of ecological remediation of contaminated soil,and the ecological principles which should be obeyed in ecological remediation.Bioremediation is very important for ecological remediation,and the method organization should obey the principles of technique optimization.Remediation efficiency can be improved if self-clean function of soil system is strengthened and activated,together with external clean function.Ecological factor adjustment is essential for contaminated soil remediation,and also,a basic characteristic of ecological remediation and an important means for the enhancement of remediation efficiency.Ecological remediation should be harmonious, efficient,and stable.The final objective of ecological remediation is to restore the ecological service function of soil,in which,the evaluation of ecological remediation is the base.Ecological remediation theory shall play an important role in contaminated soil remediation.
