“十三五”国家重点研发计划农田镉砷污染防治领域资助情况概述

镉、砷是农田土壤重金属污染的主要元素,对农田生态系统健康和农产品质量安全构成了严重威胁。"十三五"期间,国家重点研发计划"农业面源和重金属污染农田综合防治与修复技术研发"重点专项中设置了14个农田镉、砷污染防治领域项目,对农田镉、砷污染防治的基础研究、关键技术研发和集成示范应用予以资助。文章梳理了相关项目的立项背景和研究内容,介绍了项目立项和组织实施的最新进展,并对预期研发成效进行展望。

Brief introduction to research projects on prevention and control of cadmium and arsenic pollution in croplands supported by National Key R&D Program of China in 13th Five-Year Period

Cadmium and arsenic are major heavy metal pollutants in croplands, posing serious threats to cropland eco-system health and agro-food safety. During the 13th Five-Year Period, a National Key R&D Program of China was initiated titled "research and development on integrated prevention and control techniques for agricultural non-point source and heavy metal polluted croplands", in which 14 research projects focused on the area of cadmium and arsenic pollution in croplands. The research projects covered fundamental research, key generic techniques development, integration and demonstration. This article introduced backgrounds, research missions and latest progress of the projects and provided outlook for the research effects.
