With risk management as basic principle, sustainable remediation and safe utilization of contaminated sites has become an urgent environmental and developmental issue worldwide. To promote the application of rapid, economical and effective risk management and control technologies at the early stage of the soil pollution prevention and control drive in China, while specifying attributes of the broad and narrow connotations of risk management and control of contaminated sites, the paper elaborated systematically the technical theory, engineering implementation and applicable conditions of the risk management technologies in narrow connotation, including engineering control, institutional control and monitored natural attenuation, analyzed the risk management and control systems in developed countries, with reference to the risk management and control mode supported by the technical system and policy system established on the reality of the soil environmental management in China. In the end, aiming at the problems of weak foundation, unsound system and insufficient technical support of the risk management and control system in China, the authors put forth an overall layout of "prevention-control-remediation-management" for risk management and control of contaminated sites in consistence with the idea of green sustainability and the theory of life cycle management, which is expected to be of great practical significance to promotion of application of the technology and improvement of the risk management level.
