According to all the weather data of cities and counties in Jilin Province from 2001 to 2012 publicly released by the National Weather Service, this paper took the corn as research object, and calculated the equilibrium moisture content of grain by combining the effects of temperature and relative humidity on grain storage through grain heat and humid balance theory and model, and adopted the spatial data analysis tool of GIS together with mathematical cluster analysis to delimit the ecological area for food storage in Jilin Province, which overcame the drawbacks of single factor division and provided a reliable scientific basis for grain storage safety. This study analyzes the characteristics of climate in each grain storage area for appropriate method recommendation of grain storage. Dividing food storage area provides a scientific basis for scientific grain storage and grain storage security, and provides a theoretical basis for establishing applied technology and management systems according to the charac
