Abstract: To effectively determine the effect of continuous rain in spring and summer on the production of peach in Tianshui, statistical method and risk principle were used to extract the main disaster factors and even construct the model of meteorological disaster risk assessment. The main disaster factors affected the production significantly when peach began fruit- setting in early May and peach began fast growing and inflating to mature from late July to early August. The continuous rain occurred in early May was the worst factor and the contribution rate was up to 83%. Among these two periods, the mild disaster occurred most. The results showed that mild and major disaster evaluation accuracy were 75% and 83% , and the evaluation accuracy of moderate and severe disaster were up to 100%. The disaster evaluation result was ideal and had reference value in agricultural disaster prevention and reduction.
