摘要
本文系统分析了大气臭氧(O_(3))污染对我国农作物的多维度农业风险评估,通过梳理O_(3)评估指标的发展历程,全面探讨了不同指标在农业风险评估中的适用性和局限性,重点阐述了O_(3)通量的观测与计算方法及其在农田生态系统中的应用。研究揭示了O_(3)干沉积特性及其分配规律,并基于暴露-响应关系模型,深入综述了O_(3)污染对我国主要农作物产量影响的区域评估结果。研究指出,气孔O_(3)通量指标在评估O_(3)对作物影响时较传统浓度指标更具生物学意义,结合空气质量模型可更精准地开展区域O_(3)农业风险评估。未来应加强基于开放式气体浓度富集系统的大田试验,建立不同作物品种与评估指标间的关系,为优化区域O_(3)污染治理策略、保障粮食安全提供科学依据与技术支撑。
This study conducted an in-depth and systematic analysis of the multi-dimensional agricultural risk a ssessment concerning atmospheric ozone(O_(3))pollution on crops across China.Through a comprehensive review of the evolution of O_(3) assessment metrics,the applicability and limitations of various indicators in agricultural risk assessment were rigorously evaluated,with particular emphasis on the observation and calculation methods of O_(3) flux and their practical applications in agroecosystems.The research elucidated the characteristics and distribution patterns of O_(3) dry deposition.Based on exposure-response relationship models,regional evaluation results of O_(3)-induced yield losses in major Chinese crops were synthesized.The findings revealed that stomatal O_(3) flux i ndicators hold greater biological significance compared to traditional concentration-based metrics in assessing the impact of O_(3) on crops.Moreover,integrating these indicators with air quality models was demonstrated to enhance the precision of regional O_(3) agricultural risk assessments.Looking forward,priority should be placed on conducting field experiments utilizing open-air concentration enrichment systems.This approach aims to establish relationships between crop varieties and assessment metrics,thereby providing scientific evidence and technical support for o ptimizing regional O_(3) pollution control strategies and safeguarding food security.
