Abstract: Dispatching water level(volume) of the reservoir to make full use of climate resources and realize the reservoir's economic benefit in fighting the drought and generating electricity,currently is one of important issues to be resolved in the decision-making of reservoir management.According to meteorological and economic principles,applied continuous function for extreme methods and economic parameters of Yangquan reservoir,the optimal decision-making patterns in the reservoir management was established.By the application of these patterns,the obvious economic benefits had been achieved.

Key words: Climate application, Climate application, Reservoir dispatching, Method study, Optimal decision
