依据已有的研究结果， 分析了全球变化的趋势和温室气体（特别是CO2） 对气候变化的贡献和影响以及气候变化对我国和世界农业地理分布和农业生产的影响。分大区分析了气候变化对水稻、小麦、玉米等影响情况。提出了我国农业对全球气候变化应采取的战略对策和措施， 这些对策和措施可分为减缓温室气体排放和适应气候变化两部分。

The change of greenhouse gases and its contribution to climate change, as well as impact of climate change on geographical distribution of crops in China and in the world are analyzed in the paper. Temperature will increase notably when CO 2 concentration double the present and the trend will be more obvious in northern China. This paper reviewed the influence of climate change on paddy, wheat and maize in different part of China. Adaptive strategy for different types of agricultural production and agro ecosystem in China was given, and diminution strategy such as controlling the discharge of greenhouse gas was also discussed. They include: (1) the strategies and measures of slowing down greenhouse gases discharge, further divided into non industry and industry gases let out. For example, to increase the coverage of vegetation and to control grassland degradation and desertification are non industry methods. And retarding the industry gases let out or traffic vehicles gases discharge belongs to industry method. (2) The adaptive strategies after the greenhouse gases increase include adjusting land use and plant system, improving the agricultural ecological conditions and so on.
