摘要
根据1994～2004年我国粮食生产相关指标的统计数据,运用灰色关联理论对影响我国粮食生产的主要因素进行了关联动态分析,定量分析了粮食总产量与各因子的关系密切程度,指出了粮食单产、粮食播种面积、有效灌溉面积及受灾面积是影响中国粮食生产的最重要因素;提出了相关的发展对策。
Based on the grain production data and agriculture statistical data from 1995 to 2005, factors of grain production in China is discussed by the model of gray correlative analysis. The results show that per unit area grain yield, effective irrigated area, grain sown area and stricken area are the most important factors that affect grain production. The measures for the sustainable development of the grain have been brought out through the results. This paper provides a scientific basis for sustainable agricultural development in China.
