集对分析法在连江流域年径流丰枯分类中的应用研究OA
Set Pair Analysis in Annual Runoff Wet-dry Classification of the Lianjiang River Basin
将集对分析法引入年径流丰枯分类研究中,并以连江为具体研究区域,对该流域高道水文站1991-2020年的径流丰枯状况展开系统性剖析.结果表明,采用集对分析方法进行年径流丰枯分类效果较好,指示性强;相较于均值标准差等方法,该方法能充分整合径流量数值大小与时程分配规律两方面信息,不仅原理简单、操作便捷,其分类结果也更贴合年径流丰枯的实际情况.年径流丰枯分类准确度的提升,在水资源管理和防洪减灾等方面均具有显著的实际价值与应用意义.
Set pair analysis is applied to the study on the annual runoff wet-dry classification,and an in-depth analysis is conducted on the runoff status in Lianjiang River Basin from 1991 to 2020.The results show that the set pair analysis method has a good effect and strong indication in the classification of annual runoff.Compared with conventional methods such as the mean-standard deviation method,The Set Pair Analysis Method makes full use of the information of runoff and its time distribution.It is not only simple in principle and easy to operate,but also the results of classification can better reflect the actual situation of annual runoff.The improvement of the accuracy of annual runoff classification has significant practical value and application significance in water resource management,flood control and disaster reduction.
