摘要
利用东北地区１００个气象台站１９７１—１９９０年气象和产量等资料，分析了东北地区主要粮食作物的气候适应性，并计算了气候生产潜力。结果表明：东北地区中部平原区的气候生产潜力在区内都是较高或最高的，而５０°Ｎ以北的北部地区和东部长白山天池附近，作物的气候生产潜力在区内最低。最后，用线性规划对东北地区部分县的主要农作物结构提出了调整意见。理论分析结果表明：结构调整更有利于农作物高产、稳产和高效。
sing the data of meteorology and crop yield in 100 meteorological stations in Northeast China from 1971 to 1990, the climatic adaptability of main food cropps are analysed and the climatic productivity are calculated. The results showed that the agroclimatic productivities for each crop are higher or highest ic the middle plain part of Northeastern China. hut in the northern part of 50°N and near by the Tianchi of Changbai Mountain are the lowest. At last,the structure patterns of main cropps are adjusted by using linear programming. The theory analysis of results showed that the structure adjustment is more beneficial to higher yield I stability and higher value.
