【Objective】 The objective of this study is to address the defects of conventional crop risk assessment approach and to assess the crop yield risk more accurately.【Method】 A new approach based on mixed source of data has been proposed and used to assess the yield risk for maize,wheat,peanut,rice and soybean of Northeast(NE) China in this paper.【Result】 It is found that the traditional approach based on yield data does underestimate the real risk of farmers’ and the bias magnitude are influenced by the crop varieties and planting location.The proposed approach can not only assess the crop yield risk accurately but also can assess the crop risk due to specific disaster.【Conclusion】 The proposed approach to assess crop yield risk is flexible and has more advantage than the traditional ones.
