Based on the situation of agricultural random supply and demand, and considering the income of product residual and the cost of stock losses, the coordination process of two-level supply chain composed of suppliers and vendors is studied. Through the analysis of profits of decentralized decision and centralized decision, the coordination model of agricultural supply chain profit-sharing contract is designed, and under the reasonable profit distribution coefficient, the supply chain can achieve optimal. An example analysis verifies the scientific and effective of the model.%基于农产品随机供求情形，并考虑产品残值收益和缺货损失成本，研究了农产品供应商和销售商组成的二级供应链的协调问题。通过对集中控制决策和分散无协调决策时的利润分析，设计了随机供求下农产品供应链利润共享契约协调模型，在合理的利润分配参数下，供应链可以实现最优。最后，通过算例分析验证了模型的科学性和有效性。
