Short summary
At present, the water footprint calculated by the quantitative method of crop production water footprint is only a field-scale water footprint, which does not contain all the water consumption of the crop growth process, so its calculated crop production water footprint is incomplete. In this study, the hydrological model SWAT was used to analyze the real water consumption in the course of crop growth, so that the actual water consumption of the crops could be more accurately reflected.
