运用Eviews6.0软件对中国粮食产量和有效灌溉面积之间的关系进行了分析,构建了两者之间的一元线性回归模型,并对所建的模型进行了参数显著性检验,最后利用模型预测了2012年和2013年的中国粮食产量。
Eviews6.0 software was used to analyze the relationship between grain yield and effective irrigated area in China. A linear regression model between the two was constructed. The model was tested for significant parameters. Finally, the model was used to predict China’s food production in 2012 and 2013.
