For the fact that output and quality of agricultural products are influenced by uncontrollable weather and controllable effort level of agricultural producer during the agricultural production process, an agri-food supply chain profit model considering weather and effort level was developed.We analyzed the influence of the adverse weather on the optimal decisions of agricultural producer and distributer, and then comparatively analyzed the optimal decisions under centralized and decentralized supply chain. Furthermore,we designed a "risk sharing + buy-back" combinational contract which is related to the weather index.The conclusions show that adverse weather reduces the effort level of agricultural producer and affects the retailer determined price by influencing both output and quality.In addition,the effort level and price are twisted under decentralized decision model.Furthemore,the influence of adverse weather will not change the state of agri-food supply chain coordination under combinational contract,which ensure a steady supply of high quality agricultural products to the certain degree.Finally,a numerical simulation is used to verify the effectiveness of the coordination mechanism.
