| Abstract: | On the basis of fully absorbing the experiences and lessons of foreign pollution treatment and remediation, combined with the actual national conditions such as management, technical level, economic strength, and natural geography, China has put forward the management idea of risk management and control of soil contamination. The risk management and control technologies of heavy metal pollution in farmland soil has the advantages of low cost, easy scale application, good promotion prospects, and realizing remediation while producing, etc. This article introduced the current research progress of agronomic regulation, alternative planting, low cadmium variety(V)+reasonable irrigation(I)+pH adjustment(P)+soil passivators and their combinations etc.(n)(VIP+n), laws and regulations, and their application requirements, analyzed their effects, mechanisms, influencing factors and existing problems, proposed the risk management suggestions, and finally predicted the future development directions of the risk management and control of China's heavy metal contaminated farmland soil. |
