摘　　要：在河南省耕地质量等级调查与评价的基础上,测算了粮食核心区的生产能力特征以及空间分布。结果显示:河南省粮食核心区实际生产能力总产为4 560.94万t,平均单产为11 647.9 kg/hm^2,实际单产最高的区域位于豫北豫西山前平原区,实际总产最高的区域位于黄淮海平原核心区。河南省粮食核心区可实现生产能力总产为10 929.80万t,平均单产为16 260.0 kg/hm^2。河南省粮食核心区近期总产增产潜力能达到约1 800万t,其中黄淮平原核心区最高,达1 000万t以上,是重要的增产区域。Based on survey and evaluation of the farmland quantity grade of Henan,the paper calculated spatial distribution characteristics andproduction capacity of Henan’s core grain production region.The results are concluded as followsThe actual capacity of grain production is 45million 609 thousand and 400 tons with an average of 11 647.9 kg per hectare.The piedmont plain of northwest Henan is the highest average yield.The highest total production yield is the core area of the Huang Huai Hai Plain.The total production capacity of grain core area in Henan Provinceis 109.298 million tons,and the average yield is 16 260.0 kg / ha.The grain yield increasing potential is 18 million tons with Huang Huai HaiPlain’s 10 million tons outstanding the most.
