【摘要】：针对现有集对理论径流分类差异性细化不全面的现象,全面考虑径流5类丰枯分级标准的同一性、轻度差异性、中度差异性、重度差异性和对立性5种特性,建立五元集对分析法对水库流域径流丰枯进行分类研究,并与频率分析法和四元集对分析法分类结果进行对比。实例研究结果表明:所研究的水库流域年径流丰枯类型交替出现,特丰年、丰水年、平水年、枯水年和特枯年发生的概率分别为4%、9%、45%、33%和9%,平水年居多,其次为枯水年;水库流域45年水文序列中,后23年的水文极值年出现频率较前22年有较大增加,变化环境下的水文极值现象在该流域有所体现;五元集对分析法全面考虑集对理论差异性,能充分体现流域径流丰枯类型,较其余方法更能反映年径流实际丰枯,在水文水资源分析计算中有一定的推广应用价值。
[Abstract]:In view of the phenomenon that the existing set pair theoretical runoff classification difference is not comprehensive, the five characteristics of runoff classification standards, such as identity, mild difference, moderate difference, severe difference and opposites, are considered.A five-element set pair analysis method was established to classify the runoff abundance and blight in the reservoir basin, and the results were compared with the frequency analysis method and the quaternion set pair analysis method.The results of the case study show that the types of annual runoff increase and wither occur alternately in the reservoir basin. The probability of occurrence of the year of special abundance, the year of high water, the year of average water, the year of dry water and the year of special dry water are 4% and 9%, respectively, and the year of plain water is the most, followed by the year of dry water.In the 45 year hydrological sequence of reservoir basin, the annual occurrence frequency of hydrological extremum in the last 23 years is much higher than that in the previous 22 years, the hydrological extreme value phenomenon in the changing environment is reflected in the basin, the five-element set pair analysis method considers the difference of set pair theory in an all-round way.It can fully reflect the types of runoff abundance and blight, and can reflect the actual annual runoff abundance and wither more than the other methods. It has a certain value of popularization and application in hydrological water resources analysis and calculation.
