Abstract: In recent years, the development of industrialization has led to heavy metal pollution in many agricultural areas in China. The excessive heavy metals in farmland not only affect the normal growth of crops, but also do great harm to human health, which seriously restricts the development of ecology and food health in China. In order to improve the problem of heavy metal pollution in rural areas, the current situation of heavy metal pollution in rural areas is analyzed based on the innovative ecological compensation mechanism for remediation, and the external theory, public goods theory and other relevant theories are combined to obtain the ecological compensation strategy for heavy metal farmland soil remediation, and on this basis, the basic framework of ecological compensation for metal farmland remediation is constructed. Finally, effective environmental treatment suggestions are put forward according to the development requirements of ecological compensation in heavy metal farmland areas. The case study shows that different ecological restoration schemes have been adopted for a heavy metal farmland pollution area, and the environment has been improved according to the ecological compensation scheme. The total amount of ecological compensation for heavy metal farmland is CNY 32.35 million, of which the cost of seriously polluted farmland is the highest among the environmental values, with the cost of restoration per acre of CNY 65,000, indicating that the heavy metal areas are more expensive and have more obvious impact on the environment. The research content has important reference significance for the ecological environment treatment of heavy metal farmland pollution areas in China.
