Abstract: On the basis of making full use of moving average method and GIS spatial data analysis method and other methods, the evaluation index of winter wheat meteorological disaster was determined, and the agricultural meteorological disaster risk assessment model based on the winter wheat planting area was constructed. Taking Henan province as an example, 14 stations were selected as sample data to assess the meteorological disasters of winter wheat. The results showed that the high-risk areas of drought in Henan province were mainly concentrated in Kaifeng and Anyang; The high-risk areas of dry hot wind were mainly concentrated in the north and central part of Henan province; And the high-risk areas of late frost were mainly distributed in the hilly areas of Henan province.

Key words: winter wheat, planting area, meteorological disaster, risk assessment
