Abstract : With the increasing contradiction between water supply and demand in large-scale irrigation areas in Northwest China, food production security has gradually become a major threat. The traditional optimized canal water distribution model is mainly based on the objective function to optimize the crop water demand configuration, and the objective function parameters and constraints are more complicated. It is difficult to achieve global optimization of water distribution. This paper takes the Xidon
