摘　　要：文章计算了黑龙江省75个县市3种主要作物的光温生产潜力和气候生产潜力,讨论了黑龙江省作物气候生产潜力的稳定性。结果表明,黑龙江省光温及气候生产潜力差异较大,且从北到南呈增加趋势;气候生产潜力越大的地方,变率越小;气候生产潜力越小的地方,变率越大。The agricultural climatic productivity potential of three main crops （rice, maize and soybean） for all the counties in Heilongjiang Province was calculated. Meanwhile the stabilities of crop climatic productivity potential for all counties were calculated and analyzed. The results showed that there were significant difference in photosynthesis-temperature and climatic productivity potentials among different locations due to the large latitude span of Heilongjiang Province. Photosynthesis-temperature and climatic productivity potentials increased from the North to the South significantly. The larger climatic productivity potential, the smaller variation, and the smaller climatic productivity potential, the larger variation.

关 键 词：作物光温生产潜力 作物气候生产潜力 稳定性
