粮食种植面积的影响因素分析

Study of Factors Affecting Grain Planting Area

为了研究影响粮食种植面积的因素,本文以实行粮食最低收购价的小麦和稻谷为研究对象,使用SPSS统计软件,对影响种植面积的评价指标进行相关性分析,筛选出显著相关的指标,建立回归模型;从模型的整体显著性、拟合优度以及误差分析方面进行模型可靠性检验。结果表明模型可靠性高,而且对于不同的粮食品种,影响其种植面积的因素也不同。

In order to study the factors which affect grain planting area,choosing wheat and rice on which the policy of minimum purchasing price has been adopted as the example,the paper makes a correlation analysis of the evaluation indexes affecting the planting area by using SPSS.With the significantly related indexes screened out,a regression model is established.Its reliability is tested by its overall significance,goodness of fit and error analysis,showing that the model is of high reliability.It is concluded that the factors affecting the grain planting area vary with grain varieties.
