Abstract: To find out the weather risk factors that affect the wheat production in Shandong Province, and explore the relationship between the relative weather production and weather risk factors of wheat, the data of wheat yield and weather risk data from 1980 to 2009 on 120 monitoring stations in typical wheat ecological regions were collected. The statistical analysis method was used to carry out the correlation and regression analysis on the weather factors that lead to wheat yield reduction and the relative weather yield to confirm the factors that lead to the cold and frozen, drought and dry-hot wind etc disasters. The weather risk assessment model group of wheat in Shandong Province was built, and the system was realized by computer. The system analyzed the weather factors occurred during wheat producing, predicted whether there were weather disasters and estimate the risk. The system provided the government with decision-making basis to guide the agriculture production and formulate agricultural insurance rate, insurance subsidy, the lowest protective price of grain and the direct subsidy standard etc.
