基于气候变化视角的粮食安全问题分析

摘要

在气候变化大背景下，年平均气温上升、年降水量不稳定、臭氧层遭到破坏、酸雨增加，同时极端天气不断出现，造成了粮食种植范围发生改变，粮食产量减少，粮食生产环境破坏，粮食光合作用减弱等负作用，从而影响到了粮食安全。要从提高应对气候变化的抗灾能力、落实资金和技术保障、完善粮食储备管理、加强国际交流与合作等方面来提高应对气候变化能力，维护我国粮食安全。%In the climate change context,the annual average temperature is rising,precipitation is not stable,the ozone layer is destroyed,acid rain is increasing,and extreme weather is appearing,which bring out these negative effects:the grain planting areas are changed,the grain outputs decrease,the grain production environment is de-stroyed,the grain photosynthesis is weakened and so on,which influence grain security.In order to safeguard our national grain security,we should improve the ability to respond to climate change,implement financial and techni-cal supports,improve grain reserves management and strengthen international exchanges and cooperation and so on.
