摘  要:
选择粮食作物播种面积、农药施用实物量、化肥施用折纯量和农用机械总动力作为主要影响因素研究未来河南省粮食产量的变化状况,基于1998—2013年各指标的统计数据建立原始决策表,运用粗糙集理论对决策表进行属性约简。结果表明,粮食作物播种面积、化肥施用折纯量和农用机械总动力是河南省粮食产量的主要影响因素,且相对于粮食产量的重要性程度依次降低。据此,从粮食作物种植面积、科技研发投入和农机补贴政策3个方面提出了提高河南省粮食产量、保障河南省粮食安全的建议。

摘  要:
The paper chooses total sown areas of grain,consumption of chemical pesticides,consumption of chemical fertilizer by 100% effective component and total power of agricultural machinery as the main influence factors to study the future situation of grain yield in Henan Province,basing on the1998—2013 statistical data of every index,to build the initial decision table and uses the rough set theory to implement attribute reduction. The results show that the total sown areas of grain,consumption of chemical fertilizer by 100% effective component and total power of agricultural machinery are the key influence factors for grain yield of Henan Province,and their importance decreases in turn.According to the result,the paper offers proposals for increasing grain output to guarantee food security in Henan Province.
