At present,the strictest water resources management system is being deepened in China,and the"three red lines"have played a crucial role in water resources management.However,it is not closely related to"real water saving",micro-individual management and efficiency management of water resources utilization,so it is urgent to explore more effec-tive means to improve the water resources management system in the new era.On the basis of fully considering the applica-bility of water accounting system in different levels of accounting subjects,combined with the application demand of water accounting system in irrigation district,the water consumption process in the physical mechanism of water cycle is integrat-ed with each link of water accounting system.From the perspective of refined accounting,the water-related elements of ag-ricultural production in the irrigation area have been re-designed in terms of accounts,and a system of water accounting methods oriented to water consumption management has been proposed.A water accounting system framework oriented to water consumption management was constructed,and an example application was carried out in the case of Yong'an Village Irrigation District in the Hebei Plain.The results are as follows.The system effectively strengthens the control and manage-ment of the water consuming side.By adjusting the planting structure(three schemes)and irrigation methods,the water consumption of farmers'agricultural irrigation decreased by 38.8％,22.2％,60.0％and 39.8％,and the water consump-tion decreased by 36.6％,19.0％,56.5％and 8.2％,respectively.It can reduce all kinds of water liabilities and effec-tively improve the economic benefits of farmers.Compared with the traditional model,the water accounting system proposed in the paper is more suitable for water resource management in irrigation areas,and also conforms to the development needs of the strictest water resource management system and the construction of water-saving society in the new period.
