2004—2012年河南五地市粮食产量影响因子的灰色关联分析

选择了农业从业人员、农业机械总动力、农村用电量、农用化肥使用折纯量、农用塑料薄膜使用量、农药使用量、粮食作物播种面积、粮食单产等8个因子,运用灰色关联分析方法,对河南省周口、信阳、商丘、驻马店、南阳五地市2004—2012年粮食产量进行关联性分析.结果表明,8个因子对这5个地市粮食产量影响排名差别较大,基于此,提出粮食增产稳产的建议.

Grey Correlation Analysis of Grain Production Influencing Factors in Five Districts of Henan Province from 2004 to 2012

This paper analyzed grain production of Zhoukou,Xinyang,Shangqiu,Zhumadian and Nanyang Districtsfrom 2004 to 2012 based on gray correlation analysis. Eight factors such as farmer＇s number,total power ofagricultural machinery,electricity consumption in rural areas,consumption of chemical fertilizer by 100% effectivecomponent,plastic film use for agriculture,pesticide use,sown area of grain and per unit area yield of grain were usedin the model. The results showed that 8 factors have different effects on the correlation order of grain production in 5 districts. Suggestions were given on how to improve the grain production of Henan Province.
