With the intensification of global climate change and the rapid development of the social economy, problems such as water shortage and water ecological damage have become increasingly prominent. Water resources have become a key strategic resource restricting China's sustainable development. The rigid constraint system for water resources, as an important institutional innovation in national water resources management, provides a mandatory framework for comprehensive water resources planning by setting the "red line" and "bottom line" for the development and utilization of water resources. Based on the core connotation of the rigid constraint system of water resources, this paper systematically analyzes the practical challenges currently faced by the comprehensive planning of water resources in China. From four dimensions: reconstruction of planning goals, optimization of spatial layout, innovation of allocation mechanism, and improvement of control system, it proposes comprehensive planning strategies for water resources that meet the requirements of rigid constraints. To provide theoretical support and practical reference for the sustainable utilization of water resources and the high-quality development of the economy and society in our country.
