摘　　要：以东北三省71个站点的气象资料为依据,运用逐步订正法计算了玉米、水稻、大豆的光温生产潜力和气候生产潜力,讨论了温度和水分对气候生产潜力的影响。结果表明,东北三省主要粮食作物的光温生产潜力和气候生产潜力由东南向西北差异较大,呈递减趋势。且玉米最适宜种植在吉林省平原地区,水稻最适宜在辽宁省东南部种植,大豆则适宜种植在北部、东部低温或多雨地区。Using the data in 71 meteorological stations in Northeast China, the photosynthesis potential productivity, the photosynthesis-temperature potential productivity and the climatic potential productivity of the main grain crops （maize, rice, soybean） were calculated by the step by step revisal method. Impact of temperature and precipitation to climatic potential productivity was discussed. Photosynthesis-temperature potential productivities and climatic potential productivities of the main grain crops in Northeast China showed a significant difference in the different sites, which led to an increase of the climate potential productivity from northwest to southeast gradually. The results also showed that maize was most adaptable in plain of Jilin Province, rice was best grown in southeast Liaoning Province, and soybean was better grown in north and east of the region which is cold and rainy.
