摘要
基于统计资料,应用SPSS对影响研究区粮食产量的因素进行相关分析,通过建立一元线性模型和G(M 1,1)模型,对2015年人口、耕地面积、粮食产量、粮食单产进行预测。在此基础上,提出保护耕地、加大对耕地的投入等措施,以提高粮食单产水平和粮食产量,确保粮食安全和耕地的可持续利用。
Based on statistic data, in this paper SPSS was utilized to do correlate analysis of the factors influencing grain yield. Population forecast was completed by regression analysis of SPSS. Cultivated land, grain yield and grain yield capital were completed by GM(1,1). The result showed: in 2015, the cultivated land per capital was 0.11 hm^2 and the grain yield per capital was 358 kg. In order to solve grain food security and realize the sustainable development of cultivated land, we should be to protect cultivated land, to increase investment in cropland and so on.
