科学有效地开展土壤污染防控与治理修复,从农产品质量安全的源头上保证产地环境安全,已日益成为公众关注的热点。本文阐述了新时代土壤科学的新使命与功能定位,分析了我国农用地土壤污染防控与修复研究和实践的进展动态,从促进农业绿色发展和高质量发展出发,提出了我国土壤污染防控与治理修复及产业化发展的战略重点与技术路径。

How to take scientific and effective countermeasures to prevent and remediate soil contamination,so as to ensure the quality and safety of agricultural products,has become a great public concern in China.This paper illustrated the status and functions of soil in the new era and proposed that a modern soil science research and development system adaptable to the green and high-quality development of the economy and society be established.The progress in research and development on contamination control of agricultural land and quality safety of agricultural products,including prevention and control of agricultural non-point source pollution,soil contamination control and remediation to ensure the quality of farmland,and standardized production of agricultural products and supervision of their quality and safety,was systematically reviewed.Furthermore,the strategic focus and technical approach for science and technologies on soil contamination prevention,control and remediation,along with their industrial applications,were proposed to promote the green and high-quality agricultural development.The strategies to achieve this objective should be focused on(1)soil investigation planning based on scientific soil classification and categorization,(2)further development of soil environmental quality standards,as well as the monitoring and early warning system,(3)development of the green and sustainable remediation models with strong scientific and technological support,and(4)improvement on the policy-making framework and institutional innovations.
