The water budget management system and the planned water use management system play a critical role in ensuring the rational allocation and efficient utilization of water resources. While the planned water use management system is relatively mature

and its integration with the existing planning system requires further clarification. This paper analyzes the connotation

core components

and current challenges of the water budget management system

as well as the framework

legal basis

and key issues associated with the planned water use management system. On this basis

the relationship between the two systems is examined

and from the perspective of institutional coordination

the paper explores the necessity of gradually replacing the planned water use management system with the water budget management system. Targeted recommendations are proposed to improve the water budgeting framework and support its effective implementation.
