Removal efficiency and potential of N and P by Salix gracilistyla Miq. are determined in continuous flow tanks as a function of hydraulic retention time (HRT, days) and nutrient concentration (NC). Results show that the removal efficiency was longer HRT and lower nutrient solution. And also removal potential was higher at shorter HRT and higher nutrient concentration, and the regression equations were estimated. Mean above ground biomass of Salix gracilistyla Miq. in the middle reaches of Suip stream was 4880.81 g/$m^2$, and estimated removal by this vegetation from biomass and estimated equation above were 0.49~15.49 NH$_4$-N kg/day, 5.83~405.39 NO$_3$-N kg/day, 7.57~23.22 PO$_4$-P kg/day in Suip stream, respectively when HRT was 0.59~5.21, inflow concentration was 0.05~0.4, mg/L NH$_4$-N, 1.42~11.36 mg/L NO$_3$-N, 0.1~0.27 mg/L PO$_4$-P. According to this study, it is concluded that Salix gracilistyla Miq. are contribute by their high biomass and for water quality improvement of stream through nutrient removal potential.
