Fisher最优分割法在澄碧河水库汛期分期中的应用
Application of Fisher Optimal Partition on Flood Season Staging in Chengbihe Reservoir
摘要
Abstract
Taking Chengbihe Reservoir as a study example,five indicators of rainstorm days,ten-day mean rainfall,biggest three days rainfall in a period of ten days,ten-day average inflow for years and times of flood peak every year are introduced to calculate flood season of Chengbihe Reservoir by adopting Fisher optimal partition method based on the analysis of flood season characteristics of Chengbihe Basin.The flood season is divided three periods of pre-flood season,main-flood season and postflood season.The results show that the Fisher optimal partition method can not only consider multiple indicators,but also can effectively avoid the subjectivity in the selection of threshold and optimal number of dividing.Comparing with the results of other study methods,the Fisher optimal partition method is more objective and scientific and the results are more reasonable and believable.关键词
