基于气候变化视角的粮食安全问题分析

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。

An Analysis of the Grain Security Issue from the Perspective of Climate Change

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.
