Abstract
Based on the analysis of crop concentration and comparative advantage in Henan Province from 2002 to 2022,the temporal and spa-tial 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 mechaniza-tion and agricultural science and technology,the yield of crops in Henan has been increased obviously,the cultivation of main crops has a cer-tain degree of spatial agglomeration.The results of this study provide a theoretical reference for guiding the optimization of crop production dis-tribution.关键词
