摘　　要：综述了气候变暖对水循环、粮食作物生产和粮食安全影响的研究进展。未来气候变暖造成的热浪以及作物生长季节温度的不确定变化导致的农业减产,将严重威胁世界的粮食安全。近些年许多地区热浪增强、强降水事件增多、干旱持续时间延长,表明了全球应对气候变暖采取减排和适应对策的紧迫性和复杂性。减缓温室气体的排放是全世界的共同责任,而适应气候变暖所采取的相应对策则是区域行为,因而难度很大。世界各国应该共同合作,集合世界的力量应对全球变暖的挑战。The effects of climate warming on the hydrological cycle,crop production and food security were reviewed.Future climate warming which causes heat waves and uncertain crop growing season temperature will be a serious threat to world food security.These extreme events such as increasing heat waves,increasing incidence of heavy precipitation,and drought duration in many regions in recent years caused enormous consequences for lives,livelihoods,and property.Therefore,the wise innovation and application of science and technology to improve human health and well-being and to maintain the earth continuously as a home for human beings are the responsibility of each generation of people on the earth.It is also urgent and complex to take global mitigation and adaptation responses to climate warming.Reducing greenhouse gas emissions is a shared responsibility throughout the world.The adaptations to the beneficial or harmful effects of climate warming are regional actions.It is very difficult for human to adapt the harm of extreme weather events such as drought,floods and heat waves.Countries in the world should work together to collect the power of the world to address global warming challenges.
