What suggestions are there to ensure the safety of land use? (a) strict environmental access, control pollution emissions 1, and strictly control the pollution of industrial and mining enterprises and key industries. Strict environmental access and pollutant discharge permit for new projects, strengthen the prevention and control of soil pollution in new projects, focus on new industrial land, and establish a system of compulsory investigation, evaluation and filing of soil environment. For projects that may have a significant impact on the soil, such as non-ferrous metals, leather products, petroleum and coal, chemicals and medicines, lead-acid battery manufacturing, mining, printing, hazardous waste, gas stations, etc. In environmental impact assessment, soil evaluation must be carried out and the background value of soil environmental quality of characteristic pollutants should be monitored. 2. Prevent agricultural production and urban life pollution. Strictly regulate the production and use of veterinary drugs and feed additives in aquaculture, and establish a monitoring system for livestock manure, biogas slurry and biogas residue. The main pollutants in livestock manure, biogas slurry and biogas residue can only be used after reaching the standard to prevent the pollution of veterinary antibiotics, hormones and heavy metals to the soil; Guide the rational use of chemical fertilizers, control the use of chemical pesticides, prohibit the production, sale and use of ultra-thin agricultural films, and promote ecological agriculture by market means such as agricultural product traceability system; Standardize sludge disposal in sewage treatment plants and establish disposal monitoring and reporting system. Sewage treatment plant sludge, dredged sediment, tailings, etc. , to be used in agriculture, must be monitored and tested by the environmental protection department in conjunction with the agricultural department, and can be used in agriculture only after reaching the standard. 3. Joint prevention and control of water, gas and soil. It is suggested that the arrangement of pollution prevention funds should be considered as a whole in terms of water, gas and soil pollution, and the water and gas analysis of soil pollution sources and corresponding work should be done well. The bearing capacity of soil pollution should be considered comprehensively when formulating water and gas standards. Strictly regulate the storage and discharge of solid waste around industrial and mining areas to prevent heavy metal pollution to downstream valleys or farmland caused by heavy rain scouring and river carrying. (2) Improve laws and regulations, standardize the supervision process, and build relevant laws and regulations. It is suggested to promote the construction of laws and regulations on soil environmental protection, formulate laws and regulations on land use and soil pollution damage liability insurance based on environmental safety, introduce supporting policies, measures and implementation rules, clarify the main body responsible for soil pollution prevention and control, implement strict accountability mechanism for soil pollution, and strengthen supervision and enforcement of soil environmental pollution prevention and control and daily supervision and enforcement. 2. Establish relevant systems. First, focus on new industrial land, and establish a system of compulsory investigation, evaluation and filing of soil environment; Second, based on key monitoring enterprises such as waste gas, waste water, heavy metals, sewage treatment plants, livestock and poultry breeding, etc., establish a list system of key soil pollution sources, monitor pollutants regularly and update them dynamically according to the results; The third is to establish a monitoring and reporting system for the disposal of sludge, tailings, biogas slurry and biogas residue, and prohibit the use of waste water and waste residue that have not been inspected and safely disposed of in agriculture; Fourth, establish a farmland soil monitoring system, carry out routine monitoring of cultivated land, water sources and sensitive plots, carry out quality inspection of agricultural products, and evaluate the impact of soil pollution on the quality of agricultural products and water sources and the health risks to people; The fifth is to establish an environmental monitoring risk assessment system that changes the nature of land use. If the use of contaminated land changes or the owner changes, it shall carry out soil environmental risk assessment and repair the soil environment in accordance with the regulations. Without risk assessment or the quality of soil environment can not meet the requirements of relevant land use, relevant certificates shall not be issued; Sixth, establish the management system of soil archives and information registration and the risk assessment system of contaminated land; Seventh, establish the target responsibility, effectiveness evaluation and assessment mechanism of soil environmental protection, and include the determination and supervision of priority areas of soil environmental protection, the determination and management of soil environmental quality grade, the environmental risk management and control of contaminated plots and the construction of soil environmental supervision capacity into the target assessment content. 3. Improve the technical system and standards. First, improve the technical support system of soil environmental protection, and study and formulate technical specifications for soil environmental quality investigation of different land use types in our province; The second is to formulate technical specifications for soil pollution control and remediation, and environmental risk assessment and evaluation standards for site soil environment investigation and remediation; Third, according to different land use types and soil types, formulate and publish quality standards; The fourth is to formulate control standards for pollutants in organic fertilizer, biogas slurry, biogas residue and agricultural sludge. 4. Establish a departmental linkage mechanism. Straighten out the responsibilities of various departments in soil pollution prevention and control and the linkage relationship between soil pollution prevention and control. Environmental protection departments should co-ordinate soil environmental quality monitoring, risk plot investigation, risk assessment, treatment and restoration; Urban and rural construction departments, land and resources departments and agricultural departments are respectively responsible for land safety process management. (3) Make clear the pollution situation, realize the land safety 1, and make a detailed investigation on the soil pollution situation. As soon as possible, we will carry out an encrypted survey of soil pollution in key areas, find out the area, distribution and degree of soil pollution in agricultural land, investigate enterprises in production and shut down and relocate enterprises, carry out basic information collection and sampling survey of potentially contaminated plots, find out the soil pollution status and plot distribution of key industries, grasp the environmental risks of contaminated plots, and establish a list of contaminated plots and a priority control list. 2. Publicize information and guarantee the right to know and supervise of stakeholders. Construction of soil environmental safety information publishing platform, such as soil environmental quality, farmland pollution status, contaminated site registration information, pollution source distribution and its characteristic pollutants status. , and release the whole process supervision information such as soil pollution prevention, contaminated land investigation, evaluation and restoration by using convenient and standardized modes such as databases or maps. Stakeholders can retrieve relevant information through the information platform, make decisions on their own land security, and supervise the supervision work of relevant departments and the pollution discharge behavior of industrial and mining enterprises. 3. Classified management ensures the safe use of land. For contaminated land, it is necessary to carry out soil environmental risk diagnosis and assessment in accordance with relevant regulations, strengthen risk prevention, control and restoration, and focus on establishing "contaminated land file system" and "contaminated land control area and restoration area"; The responsible party shall take effective measures to prevent the spread of polluted land that has been assessed as having a serious impact on human health, and shall not be converted into urban and rural construction land, public facilities land and agricultural land before the treatment reaches the standard; The relevant departments shall not issue land use permits and construction permits if the use of polluted land is changed or the obligee is changed, the risk assessment is not carried out or the quality of soil environment can not meet the requirements of construction land. At the same time, on the one hand, relevant departments actively strive for state support, on the other hand, encourage social forces to participate after the access conditions are clear, and play an active role in land pollution restoration and reuse. The fiscal revenue of each province and various expenditures caused by land account for a large part. The government can't just allocate and use land, but it doesn't care about the safety performance of land. Because the land may still be reclaimed by the government in the future, and the rational and safe use of land is originally a matter for the benefit of future generations, and the land resources in some places are almost barren, so it is imperative to protect the land resources.
