| 摘 要： | 分析哲盟近４５年气候变化对作物生产潜力的影响，结果表明：光合物产潜力有减少的趋势；温度升高使得光温生产潜力变幅减少；受降水变率大的影响，气候生产潜力变幅最大。并从生产潜力的角度，说明了解决农业灌溉问题和充分利用热量的增加是适应气候变化，提高作物现实生产力的关键。

| Abstract: | In this paper,the impact of climatic variation in crop Potential productivity was analized.The results showed that photosynthetic potential productivity was decreasing, temperature rising rnade thevariation of light-temperature potential productivity decrease and variation of climatic potential produc-tivity was very sharP for the great change of precipitation, meanwhile, showed that sloving problem of a-griculture inigation and fully utilizing increase of heat were keys of adapting climatic changes and increas-ing crop practical preductivity. |
