英文摘要：

The basic algorithm and its flow tion of reservoir, economic operation of hydropower are introduced at first, then its application to scheduling operaand parameter calibration in hydrology field is discussed, the suggestion for future study is pointed out that should strengthen the study of adaptive mechanism and convergence performance in PSO, compare and combine with other technology, broaden the region of application to hydrology which may supply a new method for solving much optimal problem in hydrology field.
