| Abstract: | The food security early warning index system is built based on three aspects: the food supply, demand and market circulation. This paper analyzes the food security situation of Henan Province from 2013 to 2017 by the grey forecasting model and center-point triangular whitenization weight function with the help of historical data. The results showed that the food security situation in henan province is good, but the demand side is relatively weak, it should be further strengthened. |
