| 摘 要： | 根据改革开放以来河南省粮食产量以及主要影响因素的统计资料,应用灰色关联动态分析的方法,分为3个10 a作为不同影响阶段,分别选取了10或者9个影响粮食生产的因素,进行了动态分析并对比了各阶段的关联度排序,结果表明：稳定一定规模的粮食面积和从业劳动力对提高河南农业生产具有必要性。此外,亟待加大农业科技费用投入,加快河南传统农业向现代农业转化,密切关注化肥和农药使用量对粮食生产的影响变化。

| Abstract: | Based on the statistical data of grain production and main influencing factors of He＇nan Province since the beginning of reform and opening up,the grey correlation dynamic analysis was discussed.And then we averaged divided the 30 years into three stages,and picked out 10 or 9 main influencing factors to make grey dynamic analysis and comparison respectively.The result indicated that it is important for He＇nan Province to maintain the area and labor force for yield and crops production.Furthermore,It is urgent to strengthen agricultural science and technology input and accelerate the change from traditional to modern agriculture,and pay close attentation to the grain influence of dosage of pesticide and fertilizers. |
