Abstract： To address the uncertainty issues in agricultural water resource allocation，accurately allocate agricultural water resources，and achieve more scientific，rational，and efficient water resource utilization，a multi-objective integer programming mathematical model based uncertain agricultural water resource allocation method is studied. This method firstly establishes an uncertain crop water production function，and uses this uncertain crop water production function to describe the relationship between water demand and crop yield at different stages of crop growth. Based on this relationship and a multi-objective integer programming mathematical model，a multi-objective integer programming water distribution mathematical model for crop growth period is established. The Particle Swarm Optimization algorithm is used to optimize the multi-objective integer programming water distribution mathematical model for crop growth period，and the results of agricultural water resource allocation with uncertainty are obtained. The experimental results show that this method can effectively use the uncertain crop water production function to describe the relationship between crop water demand and yield，and can allcate water resources for different types of crops in diferent growth stages to effectively improve the economic benefits and quality of crops. It showed significant application effects.
