Abstract: With the help of GIS spatial analysis tools, the overall status, spatial pattern differentiation, and causes of cultivated land “non-grain production” crops in Henan Province were proved by using the grain crop planting area and total crop planting data of Henan Province as a whole and 18 prefecture-level cities. The results showed that during the “13th Five-Year Plan” period, the overall “non-grain production” level of cultivated land in Henan Province was around 30%, and there was a slow growth trend. Spatially, the spatial differences in the level of “non-grain production” in the western and southern mountainous areas of Henan Province and the eastern and northern plains were obvious. Finally, in order to strengthen the management and control of the “non-grain production” phenomenon of cultivated land in Henan Province, countermeasures and suggestions were proposed from the aspects of moderately adjusting the agricultural production structure, improving the income of grain planting, delineating the red line of non-grain production crop planting, and strengthening the construction of farmland infrastructure.
