摘  要:依据黑龙江省1980-2018年粮食生产情况,利用结构熵指标从粮食种植面积和粮食产量的角度来研究粮食生产结构的变动趋势,结果表明黑龙江省粮食种植与生产力度逐渐向高产量、高产值的优势粮食作物转移.基于系统科学理论,将黑龙江省主要粮食作物水稻、小麦、玉米、大豆的生产情况及其相互之间的关系看作一个系统.运用SPA联系数判断各粮食作物产量年度增长关系之间的同义反态势,并据此得出黑龙江省粮食生产结构的演化规律同时对未来短时间内的粮食生产结构的演化趋势进行预测,结果表明黑龙江省粮食生产结构调整的重点在于水稻和玉米生产情况的调整.According to the situation of grain production in Heilongjiang Province from1980 to 2018,this paper focuses on the changing trend of grain production structure from the perspective of grain planting area and grain yield by using the index of structure entropy.The trend of the entropy shows that that the grain-growing intensity gradually is shifted to the dominant grain crops with high yield and high output value.Based on the theory of system science,the production of rice,wheat,corn and soybean and their relationship are regarded as a system.The SPA is used to judge the annual growth relationship between the annual growth relations of grain crops,and then the evolution rule of grain production structure in Heilongjiang Province is provided and the evolution trend of grain production structure in the future is forecasted.The results show that the adjustment of grain production structure in Heilongjiang Province is mainly due to the adjustment of rice and maize production.
