Abstract
To ascertain the current status of ecological water security in the upper reaches of the Hun River,based on the long-term runoff series from the Nankouqian and Nanzhangdang hydrological stations,this study adopted hydrological methods combined with differentiated guarantee rates for wet,normal,and dry seasons,to calculate the minimum and appropriate ecological streamflow demands of the basin.The Tennant method is further employed to evaluate the riverine ecological status.The results indicate that during the wet season,ecological water supply is sufficient and the riverine ecological condition is favorable.During the dry and nor mal seasons,runoff is insufficient and ecological water deficits are significant,which may readily lead to aquatic ecological degradation.Compared with traditional approaches,the differentiated monthly frequency method that accommodates the wet-dry rhythm of the basin is more consistent with the characteristics of seasonal rivers in northern mountainous regions,and yields more reliable com putational results.The findings can provide a scientific reference for water resource management and aquatic ecological restoration in the upper reach es of the Hun River.关键词
