| Abstract: |
| The global climate change, mainly characterized by climate warming, is an unequivocal reality. Global average surface temperature 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 production 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. |
