摘　　要：在粮食生产系统中，影响粮食产量的因素有很多。根据2000~2009年安徽省粮食产量及相关指标，通过计算灰色关联度，得到影响粮食生产的相关因子的灰色关联系数由大到小依次为：化肥施用量、粮食播种面积、乡村从业人员、有效灌溉面积、农业机械总动力、农民人均纯收入，可见在选取的6个指标中，化肥施用量和粮食播种面积对粮食产量的影响最大，而农民人均纯收入对其影响较小。In food production,there are many factors influencing grain yield.Based on the grain yield of Anhui Province and the related indicators from 2000 to 2009,by calculating the grey correlation degree which indicates different influence factors of grain yield to have different impact on grain yield,we＆#39;ve obtained a descending sequence of the factors such as chemical fertilizer,total sown area grain,rural employee number,effective irrigative area,total agricultural machinery power,per capita net income of farmers.Among the 6 indices selected,chemical fertilizer and total sown area of grain have great influence on the grain yield,and the per capita net income of farmers has little influence on the grain yield.
