摘要
首先采用Spearm an秩相关系数对封丘县近12年来粮食生产的变化趋势加以分析,然后计算封丘县粮食产量与影响因素的灰色关联系数,结果表明封丘县的粮食生产在近年虽然表现出一定的波动,但总体呈增长趋势;粮食单产、化肥使用量、播种面积等是影响封丘县粮食总产的主要因素。在定量分析的基础上,提出减少封丘县粮食生产波动性,实现粮食生产稳步持续发展的基本对策。
The trend of food production of the last 12 years in Fengqiu County is analyzed by applying Spearman＇s ranking correlation coefficients. The grey correlative coefficients of food production and related factors are calculated. It is found that despite the fluctuations, food production has been steadily increasing. The grain yield, fertilizer consumption, sown land area and so on are the main factors affecting food production in Fengqiu County. Based on the above analysis, measures are proposed to meet a sustainable food production in Fengqiu County.
