基于集对分析法的年径流丰枯分类研究

Annual Runoff Classification Based on Set Pair Analysis

将集对分析法应用于年径流丰枯分类中,对北江石角水文站1991—2020年径流丰枯情况进行分析,结果表明基于集对分析的年径流丰枯分类方法可行。对比常规方法,集对分析方法充分利用了径流量的大小及其时程分配的信息,原理简单、易操作,分类结果更能反映年径流丰枯的实际。

The analysis of annual runoff abundance and depletion from 1991 to 2020 at Shijiao hydrological station of Beijiang River was carried out by applying the set-pair analysis method to the classification of annual runoff abundance and depletion, and the results showed that the results showed that the annual runoff abundance and depletion classification method based on pair analysis is feasible. Compared with the conventional method, the set-pair analysis method makes full use of the information of the size of runoff and its time distribution. It is simple and easy to operate, and the classification results can better reflect the actual abundance and depletion of annual runoff.
