摘要: 以1970~2008年广西北部湾经济区入海河流南流江和钦江的实测月径流量资料为分析对象，采用数字滤波法和最小平滑法对两条河流的总径流过程线进行了平均基流分割。结果表明，数字滤波法滤波3次得出的基流分割结果与最小平滑法得出的结果较为接近。南流江和钦江的年际总径流量变化起伏较大，年平均基流量变化稳定，两条河流的总径流和基流都表现出下降的趋势。
Abstract:  Based on the measured monthly runoff data of Nanliu River and Qin River in Beibu Gulf Eco- nomic Zone in 1970-2008, the digital filtering method and smoothed minima method are used to separate the average baseflow. The results show that the baseflow calculated by the digital filtering method filtering 3 times are similar with that calculated by the smoothed minima method. The total runoffs of Nanliu River and Qin River have large temporal variation. The baseflow changes of two rivers are stable. And the total runoff and baseflow of two rivers appear a decline tendency.
