摘要
系统分析总结前人有关气候变化对农作物生长发育影响的研究进展,重点探讨气温、CO2浓度、降水以及极端气候事件对农作物生长发育、产量及品质的影响.结果表明,气温的升高可导致农作物减产;CO2浓度升高可促进农作物生长,使农田耗水量增加,并可使粮食品质下降;降水的变化可使我国粮食遭受区域性干旱的面积增大;极端气候事件发生的概率和持续时间的增加对作物生长发育的威胁则更为严重.
Abstract
This paper systematically summarized the previous research on the impact of climate events on crop growth and development,the effects of temperature,CO2 concentration,precipitation and extreme climate change on the growth development,yield and quality of crops were discussed.The results showed that the increase of temperature could lead to crop reduction.Elevated CO2 concentration could promote crop growth,increase farmland water consumption,and reduce food quality.Precipitation changes could increase the regional drought area of China''s food.The increase in the probability and duration of extreme climate events was even more severe for crop growth and development.
