摘要
利用2000—2020年耕地利用与粮食产量相关数据,运用线性回归分析和灰色关联分析方法,分析近20年安徽省粮食综合生产能力,探究耕地利用强度与粮食产量的关联性。结果表明:近20年安徽省与全国粮食产量整体上变化趋势保持一致,而安徽省粮食产量波动较频繁,总体上呈现波动式增长;劳动力强度与粮食总产量、稻谷产量关联性最大,科技强度与小麦产量、玉米产量关联性最大。据此提出优化农村劳动力配置、促进机械化规模化经营、控制耕地物质投入强度的对策建议。
Based on the data of cultivated land use and grain yield from 2000 to 2020,the comprehensive grain production capacity of Anhui Province in recent 20 years was analyzed by using linear regression analysis and grey correlation analysis,and the correlation between cultivated land use intensity and grain yield was explored.The results showed that:In the past 20 years,the grain yield of Anhui Province and the whole country kept the same trend,but the grain yield of Anhui Province fluctuated more frequently,showing a fluctuating growth in general;labor intensity has the greatest correlation with total grain output,rice yield,and science and technology intensity has the greatest correlation with wheat yield and corn yield.Accordingly,the countermeasures and suggestions were put forward to optimize the allocation of rural labor force,promote the mechanization scale operation and control the material input intensity of cultivated land.
