To study the multi-objective high-quality operation path of the reservoir

this article takes the Cetian Reservoir as an example to conduct research. An initial indicator matrix based on the completeness of the Cetian Reservoir project

the degree of water supply guarantee

the degree of ecological water use guarantee

and the degree of modern management is constructed. The fuzzy evaluation method is used to comprehensively evaluate the current situation of the Cetian Reservoir

and measures for multi-objective high-quality operation of the Cetian Reservoir are proposed. The evaluation results show that the completeness of water-saving measures and ecological water security in the Cetian Reservoir are excellent

while the supporting level of water supply engineering and the level of industrial and agricultural water supply security are at medium level. The completeness of high standard farmland engineering

downstream ecological water replenishment

and modernization construction are relatively weak. The Cetian Reservoir should accelerate supporting water supply projects and modernization construction

gradually increase agricultural water prices above cost

explore downstream ecological water replenishment water rights system reform

implement refined management of the reservoir

and maximize the benefits of agricultural irrigation

industrial water supply

and downstream ecological water replenishment while ensuring the ecological flow in the outflow section of the river course and flood control safety of the reservoir. This will improve the high-quality operation and management level of the reservoir.
