对流域内水的储留和流径不同的水资源的可利用情况进行了评价。现在有很多种基流分割方法,但很少有针对低洼地区特性的分割方法。给出了荷兰一个低地区域的基流分割结果,根据实地观测的降水、地下水位、地表水位、流量和示踪剂分析资料来了解流域产流过程,对流量过程线用示踪剂和非示踪剂的几种基流分割方法进行分割并将其结果进行了比较。 The availability of water resources with different storage and flow paths in the river basin was evaluated. There are many kinds of base flow segmentation methods, but there are few segmentation methods for low-lying areas. Based on the data of precipitation, groundwater level, surface water level, flux and tracer analysis data observed in the field, the article gives the result of basal flow division in a lowland area in the Netherlands, Several base-flow segmentation methods were used to segment and compare the results.
