针对目前年径流丰枯分类常用方法存在的不足,鉴于年径流丰枯分类同时受年径流总量及其年内时程分配的影响,提出了基于广义集对势(GSPP)判别准则的年径流丰枯分类模型,并将该模型应用于黑河莺落峡水文站年径流丰枯分类中,判别了不同水文年的丰枯状态,划分了年径流序列的水文丰枯阶段。结果表明,该模型不仅考虑了年内逐月径流分量的权重值,同时通过广义集对势从联系趋势的角度进行径流丰枯分类,思路清晰,过程直观,在水文分类中具有一定的推广应用前景。
In view of the shortcomings of the commonly used method of annual runoff abundance classification, the annual runoff abundance based on the generalized set pair potential (GSPP) criterion is proposed in view of the annual runoff abundance classification is affected by the annual runoff and its annual distribution. The model was applied to the annual runoff abundance classification of Yingluoxia Hydrological Station in Heihe River. The abundance of wetlands in different hydrological years was discriminated and the hydrological abundance and dryness phase of annual runoff series was divided. The results show that this model not only considers the weight of monthly runoff components during the year, but also classifies the runoff by using the generalized pairwise potential from the perspective of the trend of contact. The method has a clear idea and a clear process, which has certain promotion and application prospects in hydrological classification .
