摘要:

随着气候变化的持续影响,复合干热事件的发生频率不断增加,影响了全球粮食产量。小麦作为主要粮食作物,对保障全球粮食安全和经济发展至关重要。通过总结当前全球小麦主产区复合干热事件的时空格局变化,梳理了当前复合干热事件对小麦产量的影响程度,明晰了复合干热事件对小麦产量的影响机理与研究方法。结果表明,1960—2020年全球小麦主产区发生复合干热事件的频率和强度均有所增加,已经对小麦产量形成严重威胁,预计未来会进一步增加和强化。陆气系统与作物生理胁迫的相互作用使得复合干热对小麦的影响变得更加复杂。未来研究亟需构建具有农作物生理意义的复合干热事件危险性指标,利用统计模型和作物生长模型深入探究对复合干热事件的响应机制,进一步研究不同维度、方法和模型的融合,以加强对复合干热事件的适应和风险预估,以期为深入理解复合干热事件对小麦产量的影响提供科学依据,为农业生产的可持续发展提供参考。

Abstract:

With the continuous impact of climate change, the frequency of compound hot and dry events is increasing, which impacts global food production. Wheat, as a major food crop, is crucial for ensuring global food security and economic development. This review summarizes the temporal and spatial patterns of compound hot and dry events in major wheat-producing regions worldwide, assesses their impacts on wheat yield, and clarifies the mechanisms and research methods associated with extreme hot and dry conditions. The results indicate that the frequency and intensity of compound hot and dry events in the major wheat-producing regions of the world have increased during the period from 1960 to 2020. Compound hot and dry events have become a serious threat to wheat yields, and are expected to increase and intensify further in the future. The interaction between land-atmosphere systems and crop physiological stress further complicates the impacts of these events on wheat. Future research should focus on developing compound hot and dry indicators with physiological relevance for crops, employing statistical and crop growth models to explore the response mechanisms to compound hot and dry events, and integrating different dimensions, methods, and models to gain a deeper understanding of the impacts of compound hot and dry events. This will enhance adaptation strategies and risk assessments for such events, providing a scientific basis for understanding the impact of compound hot and dry conditions on wheat yield and offering guidance for the sustainable development of agricultural production.

Key words: Compound hot and dry event, Wheat yield, Climate change, Crop physiological response, Risk assessment
