中文摘要：

本文针对国内水电开发形势以及数字化技术的发展需求，设计了基于数字流域的梯级水电工程管理系统的总体架构。然后，从技术、方法、理念、资源四个方面提出了系统建设实施原则。最后，结合中国长江三峡集团公司在长江上游和金沙江下游梯级水电工程开发实践，介绍了数字工程、数字移民、数字坝区和数字库区系统的建设内容及取得的成效。实践证明，该系统可供同类流域工程建设和运行管理借鉴。

英文摘要：

Aiming at the demand for digitalization by recent hydropower development in China, the application architecture of a cascade hydropower project digital river basin system has been designed and elaborated, and implementation principles of this complex system are formulated and discussed from four aspects： techniques, methods, ideas, and resources. Finally, we describe the practical implementation and achieved results of the digital project, digital migration, digital hub area, and digital reservoir system by China Three Gorges Corporation in engineering practice of hydropower development on the Yangtze River and the Jinsha River. Our results would be applicable to the design and construction of similar projects worldwide.
