摘要: 对流层臭氧(O3)浓度增加对作物的不利影响已受到广泛关注,臭氧模型研究自然已成为该领域的热点之一。建立有效的模型对臭氧造成的作物产量损失进行评估和预测,能为中国臭氧污染的控制和农业安全提供科学依据。根据模型与作物生长关系的紧密程度,可将其分为统计模型和机理模型2大类。本文依据模型的研究进程,依次阐述了浓度响应、剂量响应、通量响应3个统计模型;重点分析国内外影响较大的CLASS、Martin和AFRCWHEAT2-O3 3个机理模型;指出各模型的局限性,并对相关研究发展方向的可行性措施进行讨论。

Abstract: The impact of increasing ozone (O3) concentration in troposphere on crops has being drawn more and more concern, and its simulation study has become a hotspot. To build effectual simulation models to evaluate and predict the crop loss by O3 would help to the ozone pollution control and agriculture safety. According to the relationships between crop growth and O3, the models could be classified as statistical models and mechanism models. In this paper, concentration-, dose/exposure- and flux-based statistical models were introduced, based on their development process, and three influential mechanism models (CLASS, Martin, and AFRCWHEAT2-O3) were discussed in pivot. The limitations of each model were pointed out, and the development trends of related studies in China were put forward.
