| 摘 要： | 为揭示河南省粮食生产变化特征,探析河南省粮食产量变化的影响因素,利用小波诊断技术对1978—2012年河南粮食产量变化的特征和影响因素进行分析。结果表明:河南省的粮食产量波动存在5、10、20年左右的特征时间尺度,并以10年和20年左右的特征时间尺度为主。综合3种尺度下的时间特征,河南粮食生产周期逐渐增大,粮食产量变化渐趋稳定。河南粮食生产目前正处于相对丰产期,但随后就会进入新的粮食减产期。所选因素对粮食产量的影响均是正向的,他们的增加均会促进粮食产量的提高,但不同因素对粮食产量的影响大小不同,按影响程度次序为,粮食播种面积农田有效灌溉面积乡村农业人员数量化肥施用折纯量农用机械总动力农村用电量。

| Abstract: | In order to explore the characteristics and influencing factors of grain output in Henan Province, wavelet analysis was used to analyze the characteristics and influencing factors of the grain output from 1978 to 2012 in Henan Province. The results showed that grain output in Henan Province had 5 years, 10 years and 20 years characteristic time scales, and 10 years and 20 years were the main ones. Time scale of grain output tended to be longer, and changes of grain output tended to be stable. Grain output in Henan Province was in relative harvest period at present, but it would be in a new grain reduction period subsequently. The selected influencing factors of grain output were all positive, and their increases would promote grain output, but influencing levels of different factors on grain output were different. Sequence of the influencing degree was grain sown area>effective irrigation area>number of rural agricultural workers>consumption of chemical fertilizer in farmland>total power of agricultural machinery>electricity consumed in rural area. |
