综合分期方法在陈家湾水库汛期分期中的应用
|
摘要
为消除指标相关性对聚类造成的影响,避免主观地选取汛期时间域,提出综合方法进行汛期分期。使用变异系数法和灰色关联法对所选指标进行筛选,利用集对分析法划分汛期时间域,最后利用Fisher最优分割法进行汛期分期。对陈家湾水库进行汛期分期,得出结果:汛期为6月1日—10月5日;前汛期为6月1日—6月25日,主汛期为6月26日—9月5日,后汛期为9月6日—10月5日。所得结果与前人分析结果较为一致,表明该方法符合实际,有一定的适用性。
In order to eliminate the influence of index correlation on clustering,and avoid subjective selection of flood season,a comprehensive method for flood season staging was proposed.The selection index was selected by using the coefficient of variation method and grey correlation method,and the time domain of flood season was divided by set pair analysis.Finally,the flood season was divided by Fisher optimal segmentation method.The results show that the flood season is from June 1st to October 5th,the former flood season is from June 1st to June25 th,the main flood season is from June 26th to September 5th,and the latter flood season is from September 6th to October 5th.The results are consistent with the previous analysis results,which show that the method is practical and has certain applicability.
