基于熵权法的万安水库汛期分期计算
Entropy weight method-based calculation on phase-division of flood season for Wan'an Reservior
摘要
Abstract
In order to fully and objectively reflect the changing law of the rainstorm-flood season of the watershed of Wan'an Reservoir for carrying out the scientific and reasonable demonstration on the original phase-division of the reservoir,several indexes,i.e.rainstorm,flood,etc.of the watershed are necessary to be comprehensively analyzed for the study.Aiming at that large differences among the degrees of the impacts from all the indexes on the phase-division of the watershed,the entropy weight calculations are carried out on all the phase-division indexes of Wan'an Reservoir in the study with the entropy weight method that can flexibly measure the impacting effects of the indexes,and then the phase-division is made for the watershed with the information entropy value obtained from the calculation.Moreover,the result of the phase-division is compared with those from the original phase-division and the phase-division got from Fisher method.The result shows that the entropy weight method-based phasedivision is more close to the original phase-division,however,the original phase-division is suggested to be appropriately adjusted.On one hand,the objectivity and reasonability of the phase-division are ensured and more decision-making space is provided by this method,on the other hand,it is favorable to make the impacting degree analysis on all the rainstorm-flood phase-division indexes for the watershed.关键词
