广义灰色关联矩阵在粮食生产影响因素分析中的应用

The Application of Generalized Grey Correlation Matrix in The Analysis of Influencing Factors of Grain Production

采用广义灰色关联矩阵优势分析方法对河南省1990-2012年间的粮食总产量和粮食单产及其影响因素进行了分析。结果表明:粮食总产量和粮食单产受各相关因素的综合影响基本一致,说明河南省粮食总产量的增产主要依靠粮食单产的提高;而农田有效灌溉面积、化肥施用量和农用机械总动力是提高粮食单产的主控因素,应发展有机化肥逐步形成农田生态系统的良性循环;同时应严格执行耕地保护政策,确保粮食播种面积。

The article analyzed the total grain yield and grain yield per unit area of Henan Province during 1990-1992 and its influencing factors by the generalized grey correlation matrix analysis methods. The results showed that： the impact of various relevant factors on the total grain yield and grain yield per unit area is consistent,indicating that the increase of grain production of henan province relied mainly on the increase of grain yield per unit area. The main controlling factors of improving the grain yield per unit area are the effective irrigated area,farmland fertilizer and total power of agricultural machinery. We should develop organic fertilizer to gradually form a virtuous cycle of farmland ecosystem. At the same time we should strictly implement the arable land protection policy,to ensure that the grain sown area.
