【摘要】：如何定量研究历史和将来的气候变化对粮食产量的影响一直是世界范围内普遍关心的科学问题。本文综述了近年来有关气候变化对粮食产量影响的研究现状,讨论气候变化对粮食产量影响的机理、程度和范围,并介绍了应用综合评估模型对全球领域的粮食生产影响的定量分析。研究结果表明,有32%~39%的地区表现出玉米、水稻、小麦、大豆的产量波动与气候变化呈现出显著的相关关系,并且不同地区的粮食产量受到温度、降水以及它们之间的耦合作用的影响不同。通过综述研究显示,气候变化对世界农业生产产生了显著的影响,特别是对粮食产量的影响比较严重,气候变化对粮食产量影响的程度主要取决于粮食作物的种类,CO_2的施肥效应以及对气候变化的适应能力,为新时期保障气候变化背景下中国粮食安全,提高农业防灾减灾能力提供参考。
[Abstract]:How to quantitatively study the effects of climate change on grain production in the future has been a worldwide scientific issue of universal concern. This paper reviews the current research status of climate change impacts on grain production in recent years. This paper discusses the mechanism, extent and scope of the effects of climate change on grain production, and introduces the quantitative analysis of the effects of the application of the integrated assessment model on the global grain production. The results show that 32% of the regions show corn, rice and wheat. There is a significant correlation between soybean yield fluctuation and climate change, and the grain yield in different regions is affected by temperature, precipitation and their coupling. Climate change has had a significant impact on world agricultural production, especially on food production, The extent of the impact of climate change on grain yield mainly depends on the fertilizer application effect of the grain crop species and its ability to adapt to climate change, so as to ensure China's food security in the context of climate change in the new period. To improve the ability of agricultural disaster prevention and mitigation.
