介绍了粒子群算法的标准算法及流程，探讨了粒子群算法在水库优化调度、水电站经济运行、参数优选等水文领域中的研究成果和存在的问题，指出未来应该加强粒子群算法改进机理和收敛性能的研究，并与其他算法技术相比较、结合，拓展其在水文科学领域的应用范围，为解决水文领域中大量优化问题提供新途径。

The basic algorithm and its flow are introduced at first, then its application to scheduling operation of reservoir, economic operation of hydropower and 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.
