Abstract: Methods of SVD and EOF were used to construct an integrated climate factor with dekad mean temperature, dekad total sunshine and precipitation from April to September; then an economy-climate model was built in combination with economic data to assess the grain yield condition of Jilin Province. The results show that the effect of integrated climate factor on grain yield was positive, and good evaluation was received in the simulation of grain yields and the assessment of annual harvest patterns using the economy-climate model.
