A Loss Estimation Method for Agrometeorological Disasters and Its Application in Yield Prediction

Based on the expected yield without meteorological damages, a loss estimation method for agrometeorological disasters was introduced. The determinations of expected yield and its reduction by disasters were also discussed. By analysing the relationship between the yield reduction and several factors including intensity of disasters, influenced area and crop sensitivity to disasters, a constructure-based statistical model to estimate the yield reduction by damages was established.
