Abstract

基流是枯水季节河川径流的重要补给来源,河川基流量及其变化对流域生态健康和水资源合理利用具有重
要作用。确定适宜流域生态环境特点的基流分割法,在基流研究中是十分关键的工作。以北洛河流域上游典型黄土
丘陵沟壑区刘家河站的多年实测径流资料为基础,分析BFI,HYSEP、数字滤波等三类共9种基流分割法的适宜性,
结果表明:BFI法和HYSEP法分割结果比较接近,所得基流指数在0.399 4~0.428 1。尤其修正BFI法估算的基流
量及过程线,能够客观反映研究流域流量过程线退水段的物理规律。综合考虑变异性、稳定性、过程线吻合程度等方
面,认为修正BFI法是黄土区水文研究中进行基流分割的适宜方法。

Other Abstract

Baseflow is an essential supply source of streamflow in the dry season.Its variability is very important
for ecological health and water resources balance in a region.It is critical to identify a baseflow separating
method which is associated with the climatic and physiographic characteristics in the study region.Daily
streamflow data at Liujiahe gauge station of Beiluo river basin,one of the catchment in the Middle reaches of
Yellow River,were used to analyze the suitability of 9tools in three types of baseflow separation methods of
BFI,HYSEP and digital filtering.The results show that the base flow indices derived from BFI and HYSEP
turn to be consistent,and they are all between 0.399 4and 0.4 281.Particularly,the baseflow and the duration
curve estimated by revised BFI can objectively reflect the recession hydrograph.The revised BFI is expected
as the most suitable baseflow separation method for loess area in hydrological researches in terms of
comprehensive consideration of the variability,stability and the process line of the results form 9tools.
