In order to realize the sustainable utilization and maintain the healthy development of river and reservoir ecosystem, this paper applied energy value analysis to reservoir ecological operation for discussing the energy optimal operation of reservoir ecological service value. With the objective of maximizing the service energy of Manwan Reservoir and the constraints of ecological water demand and social economic water consumption, an optimal operation model of reservoir ecosystem service energy was established, and the ant colony algorithm was used to solve the model. The results show that the total service energy of Manwan Reservoir is 2.10×1022 sej in high flow year, 1.79×1022 sej in normal year, 1.58×1022 sej in dry year. Main service values are ecological regulation, water supply and ecological support, material production followed, cultural entertainment is the minimum. The results have practical value and important significance for maintaining the healthy development of the Lancang River basin, especially for the ecosystem of the Manwan Reservoir Region.
