| 摘 要： | 气候变暖已是不争的事实,预计到21世纪末全球地表平均气温仍将上升1.5℃以上。水稻是我国最重要的口粮作物,全国80%以上的人口以稻米为主食,探明气候变暖对我国“口粮绝对安全”的潜在影响意义重大。作者依据多年的田间增温试验及长期观察,并结合国内外现有研究,阐明了我国粮食主产区气候变暖的基本态势,总结发现温度升高1.5℃对我国水稻生产的潜在影响正负参半,并取决于具体的稻作季节和地区。但是,随着水稻种植制度调整,尤其是南方双季稻种植面积下降,温度升高对我国水稻生产的负面影响将逐步递增。最后,作者提出了应对气候变暖的气候智慧型稻作技术创新建议,并展望了该研究领域的重点内容和方向。

| Abstract: | The global climate change,mainly characterized by climate warming,is an unequivocal reality.Global average surface tempera ture is expected to rise by more than 1.5℃by the end of this century.Rice is the most important ration crop in China,with more than 80%of the population taking rice as the staple food.It is of great significance to explore the potential impact of climate warming on the"100%-self-sufficiency of rice"in China.Based on warming experiments and long-term field observations,the authors further clarified the basic trend of climate warming in Chinese major grain-producing areas,and concluded that the potential impact of warming on Chinese rice pro duction could be positive and negative,depending on growing seasons and regions.However,with the adjustment of rice cropping system(e.g.decrease in double rice cropping system),the negative impact of warming on rice production in China will increase significantly.Finally,the authors put forward some suggestions on the technological innovation of climate-smart rice cultivation for coping with climate warming,and the key contents and directions of this research field. |
