This article described the fundamental principles and the progress of study and application of AquaCrop model, and especially introduced the application of AquaCrop model. The application of AquaCrop in irrigation management, cropping system and the future climate scenario has achieved good results. The problems that should be paid attention to in the application of AquaCrop model were summarized. It was pointedout that most of the researches in China concentrated on single field scale; Many studies focused mostly on the calibration and verification; And the applicability of the model parameters in China remained to be further verified; The performance of Aquacrop model would be affected under severe water stress conditions.This article proposed several suggestions for future development,with a view to AquaCrop model playing a guiding role in the future of agricultural production practices.
