| 目前，中国地表臭氧污染水平已位列世界前列，对国内粮食安全造成了严重威胁。针对当前严重的大气污染，并且基于该领域的研究热点，本文综述了地表臭氧在农业生态风险方面的研究现状与展望。主要包括地表臭氧对作物产量和品质的影响与机制及其区域风险评估的方法与结果。提出了未来研究应着重关注臭氧区域风险评估的精准性和全面性，开发作物多品种的臭氧气孔通量模型以及建立科学的评估指标体系。此外，要探求高效减缓臭氧损伤的农艺管理措施，以及加强多因子复合实验的开展与无人机生态遥感监测技术的应用。 |
| 英文摘要: |
| In China, the 90th percentile maximum daily 8 h average O3 concentration(90th MDA8)has increased to approximately 80.0 nL·L-1, which is considerably higher than the damage threshold of many crops and poses a serious threat to food security. To systematically understand the effects of O3 on crops, we summarized the research status on risk of O3 in crops, including the effects and mechanisms of O3 on grain yield and quality, and methods and results of regional O3 risk assessments. In addition, several viewpoints were proposed to reinforce knowledge on the mechanism of crop grain yield loss owing to O3, establish more effective agricultural management practice to mitigate O3 damage in crops, improve accuracy and comprehensiveness in O3 risk assessment, and encourage application of remote sensing technology and multifactor experiments in future studies. |
