摘　　要：黑水河为岷江上游典型流域,流域气候变化敏感,水能资源丰富,开展黑水河流域水文气象要素变化特征的研究工作,有利于成都平原水资源的开发利用与管理。采用有序聚类法、Pettitt法、线性倾向估计法、MK趋势检验法及小波分析法等科学全面探讨了年尺度水文气象要素的演变特征。研究成果可以为流域径流演变归因分析及径流预测等内容提供理论依据,以期加深对岷江上游径流变化规律的认识。Heishui River is a typical watershed in the upper reaches of Minjiang River,which is sensitive to climate change and rich in hydropower resources.Conducting research on the characteristics of hydrological and meteorological changes in the Heishui River Basin is beneficial for the development,utilization,and management of water resources in the Chengdu Plain.This paper comprehensively explores the evolution characteristics of annual scale hydrological and meteorological elements using scientific methods such as ordered clustering,Pettitt method,linear tendency estimation,MK trend test,and wavelet analysis.The research results can provide theoretical basis for the attribution analysis and prediction of watershed runoff evolution,in order to deepen the understanding of the changes in runoff in the upper reaches ofMinjiang River.
