英文摘要：

This study demonstrates the dual characteristics in the elements of operating rule for multi-reservoir water supply, i.e. water-supply policy and water-allocation policy, and analyzes the roles and significance of these two policies. We focus on a summary and review on the advances in the research and use of operating charts, operating functions, and other specific forms of the operating rule for multi-reservoir water-supply operation. We multi-reservoir water-supply operation. also suggest some directions of further study to improve
