The Central Economic Work Conference to be held at the end of 2019 pointed out that it is necessary to fight hard against pollution, stick to the same direction and intensity, highlight accurate pollution control, scientific pollution control and pollution control according to law, and promote the continuous improvement of ecological environment quality. We should focus on the battle to protect the blue sky, clear water and pure land, improve relevant governance mechanisms, and do a good job of prevention and control at the source. Compared with air and water pollution, soil pollution is more hidden and difficult to control. We should strengthen the awareness of problems and responsibilities, and, in accordance with the requirements of the Central Economic Work Conference, adopt a multi-pronged and comprehensive strategy to scientifically defend the Pure Land.

To establish and improve the supervision system of soil pollution, we shall strengthen the management of contaminated plots, establish coordination and linkage mechanisms and regular meetings and communication mechanisms, improve work processes and standards, and strengthen the coordinated management of departments. Relevant departments in the governance area should strengthen organization and leadership, clear division of responsibilities and strengthen coordination and linkage. According to the pollution degree of cultivated land, aiming at risk prevention and control and ensuring the safety of agricultural products, adjusting the agricultural land utilization mode and crop planting structure, and the classified management of agricultural land shall befurther strengthened. We shall strengthen the cooperation between scientific research institutes and further deepen the research on the corresponding relationship between soil pollution and agricultural pollutants exceeding the standard,toestablish a mechanism to investigate the responsibility for soil remediation, and carry out risk prevention and control of substandard contaminated sites and trace back the responsibility for remediation. Before the enterprise changes the land use right, changes the land use, goes bankrupt, closes down, moves or develops the construction, they should carry on the soil environmental quality investigation and the risk appraisal work. Further, it shall establish and improve the regional ecological compensation mechanism, and give appropriate ecological protection compensation to unpolluted arable land.

To strengthen the construction of soil pollution risk prevention and control mechanism,we shall adhere to the principle of risk prevention and control, andtake measures such as source prevention and control, governance and repair according to local conditions. For lightly polluted farmland, measures such as straw returningto the fieldand ecological restoration should be taken to promote the safe use of land and ensure the quality of agricultural products. For industrial and mining land, corresponding restoration plans shall be formulated according to the development level, and basic restoration or direct conversion into green land shall be carried out to control the risk of pollution diffusion. For construction land, we shallfocus on public service land such as schools and pension institutions, and effectively prevent and control pollution risks through pollution status investigation, risk assessment and other means. We shallimplement a regular survey system of soil environmental conditions to find out key information such as pollution area, distribution and pollution degree,focus on heavy metal pollution prevention and control areas and industrial parks, and dynamically update the list of key monitoring industrial and mining enterprises and soil environmental monitoring results. We shallfurther optimize the layout of the agricultural soil environmental quality monitoring network and promote full coverage at the county and city levels,promote the reduction, recycling and innocuity of domestic waste through household surveys and supervision onvillages (communities).

To promote soil remediation through scientific and technological innovation,we shall strengthen policy guidance, increase the promotion and application of 5G, big data, cloud computing, Internet of Things, artificial intelligence and other new technologies, issue a list of soil pollution control technologies, strengthen technical training and standard formulation, and apply supporting new policies for new technologies so as to give full play to their effectiveness. The foundation database of soil environment shall beestablished, and the information management platform based on classification, classification and partition of big data shall beconstructed. Building thesoil environmental data collection and sharing mechanism of relevant departments to achieve dynamic data update, analysis and early warning. Through multi-technology combined treatment of composite pollution, developingtargeted and efficient treatment materials and technologies, developingkey convergence and supporting equipment and technologyinmulti-technology combined repair process.The deep contaminated soil collaborative remediation technologyshall be developed, to cut off the migration of pollution sources to groundwater, to achieve soil and water co- treatment. In view of the differences in pollutants and pollution levels in different stratums, the multi-technology integration coupling shall bepromoted,and layered and partitioned treatment shall beimplemented.

To break the restriction of funds for soil pollution control through multiple channels,we shall adhere to the diversified financing ideas and solve the financing problems of soil pollution treatment and remediation by classification. For land plots located in densely populated areas with great development and utilization value in the future, environmental and economic benefits should be taken into account, and remediation should be promoted through market-oriented financing methods such as soil pollution prevention fund. We shallfurther optimize the direct and indirect financing systems and improve the financing structure and benefits. Through financial allocation or injection of land, equity and other means, we canplan as a whole toestablishthesoil pollution prevention fund,buildinga platform company with the function of soil pollution control financing. We mayestablish a scientific and reasonable allocation of resources, a debt service guarantee mechanism, a continuous capital replenishment mechanism and an integrated circulation mechanism of "borrowing, using and repaying" to form an efficient management and operation system and provide sufficient financial support for soil pollution control.
