In response to the contradiction between water supply and demand brought about by the rapid development of the economy and society, this article deeply explores the optimization strategies for water resource allocation and planning in water conservancy and hydropower engineering systems. By analyzing the water cycle characteristics and water use structure of the watershed, a multi-objective optimization based water resource scheduling model was constructed, aiming to balance ecological environment protection and economic benefits output. The research focuses on the regulatory role of water conservancy hub projects on runoff at the spatiotemporal scale, and proposes a systematic approach that couples macro planning and micro configuration. The results indicate that scientific allocation planning can not only significantly improve the efficiency of water resource utilization, but also enhance the resilience of the system to cope with disaster risks in dry years. This article aims to provide theoretical basis and technical support for the sustainable management of regional water resources and the coordinated layout of hydropower projects.
