摘　　要：根据模糊集合理论,利用水库汛期水文统计信息拟合汛期模糊隶属函数参数,计算汛期各时期的相对隶属度及相应的防洪库容,据此确定水库汛期各个时期的汛限水位。实例计算结果表明,水库汛末汛限水位最高可比原来提高2.4m,增加兴利库容9000万m3。According to the fuzzy set theory, the parameters of fuzzy membership function were fitted by using the hydrology statistical information during reservoir flood season, the relative membership degree of various times of flood season and the corresponding flood control storage were calculated and then control water levels of reservoir in various times of flood season were determined. The example results indicated that the control water level of reservoir can rise by 2.4 m at the end of flood season, and effective storage capacity of reservoir can increase by 90 million m^3 correspondingly.
