| 摘 要： | 安徽省全国重要的粮食主产省。本文依据1978~2010年安徽省粮食产量统计数据，应用波动理论和灰色关联度理论分析安徽省粮食产量波动规律，考察安徽省粮食产量波动的历史过程、数量特征和影响因素。研究结果表明，安徽省粮食产量波动表现为古典型波动；周期较短，长度比较规则；波动幅度总体呈现中度；扩张期略长于收缩期；在粮食产量波动性比较中可以将各周期划分为几个阶段；用灰色关联度分析得出，化肥是粮食增产的重要因素，应该加大力度研究，合理施肥；农作物受灾面积对粮食产量的影响较小。

| Abstract: | Anhui Province is one of the major grain production provinces in China.The paper reviews the history process and quantity characteristic of food output fluctuation in Anhui Province and analyses rule of food output applying wave theory and grey relation theory with food production statistic data from 1978 to 2010.The results show that the food output fluctuation is classical fluctuation,fluctuation period is short and the length is rules,fluctuation showed moderate,is a rather long period of expansion in systolic.By comparison of fluctuation of food output,the period can be divided into several stages.With grey correlation analysis of the influence factors of in Anhui province,chemical fertilizer is the important factor of food output growth,crops disaster areas have a small impact on food output. |
