一般学者根据嘉靖八年霍韬的奏疏和《明史·食货志》的记载，认为河南省洪武二十六年的耕地数字应是１４１９４７０顷，因而以此作为研究的依据。本文认为，这一数字和实际差距太大，不能客观反映其时河南省的垦殖情况，因而从各个方面进行分析研究，并探索其形成原因。最后又经过反复比较推算，认为该年耕地面积应是２７５４８１顷。 According to the records of eight years of Taoism by Jiajing and the records of Ming Shi Shi Huo Zhi, scholars generally think that the amount of arable land in Hongwu City should be 1419470 hectares for a total of 26 years. Therefore, it is taken as the basis for the study. This paper argues that this figure and the actual gap is too large, can not objectively reflect the reclamation situation in Henan Province at that time, and therefore from all aspects of analysis and research, and explore its formation. Finally, after repeated comparative projections, that the area of ​​arable land that year should be 275,481.
