摘要
利用GIS空间分析、灰色关联分析和主成分分析方法,通过对影响河南省粮食产量自然、社会和经济因素的分析,结果显示:自然对河南省粮食产量的影响较小,粮食产量主要受社会经济因素的影响,其中粮食单产和粮食播种面积的影响最为显著。除农业从业人口外,其他因素的影响比较均衡,但与粮食产量关联度较高,对于提高粮食产量仍有较大的利用空间。农业从业人口与粮食产量呈负相关关系,不是粮食产量的主要影响因素。
This paper discusses influencing factors of grain in Henan Province with GIS, Grey Incidence and Principal Component Analysis. Results indicate that the difference of climate grain production potential has little influence on output of grain. The social and economic factors have prominent influence, and both output of grain per area and sown area of grain have most prominent influence. Except rural persons engaged in agriculture, the other investment factors have equal influence and there is biggish space in improving output of grain. There is negative correlation between rural persons engaged in agriculture and output of grain, and population is not the influencing factor.
