摘要
通过对2002—2022年河南省农作物集中度和比较优势的分析,从县域层面研究了主要农作物的时间变化和空间集聚变化。结果显示,粮食作物是河南省的主要作物,种植面积呈先上升后下降趋势,总体占比在70%左右。油料作物的占比呈先下降后上升趋势,但花生的种植面积却不断增加,并有向南迁移的趋势。棉花的种植大规模下降,占比由2002年的5.94%下降到2022年的0.07%,但整体的生产重心没有太大的迁移,仍集中在豫东地区。随着机械化程度增强、农业科技水平的提高,河南省农作物产量明显提升,主要农作物种植在一定程度上具有空间集聚性。研究结果为引导农作物生产布局优化提供了理论参考。
Based on the analysis of crop concentration and comparative advantage in Henan Province from 2002 to 2022,the temporal and spatial changes of main crops were studied at the county level.The results showed that the grain crops are the main crops in Henan,planting area showing an upward trend and then a downward trend,the overall proportion of about 70%.The proportion of oil crops decreased first and then increased,but the planting area of peanut increased continuously and moved southward.The planting of cotton declined from 5.94%in 2002 to 0.07%in 2022,but the center of production did not shift much,and it was still concentrated in eastern Henan.With the increase of mechanization and agricultural science and technology,the yield of crops in Henan has been increased obviously,the cultivation of main crops has a certain degree of spatial agglomeration.The results of this study provide a theoretical reference for guiding the optimization of crop production distribution.
