| Abstract: | Raster geographic information system,runoff curve and equation of contaminant loss are used to calculate the fluxes of terrestrial nitrogen and phosphorus contaminants into the Luoyuanwan sea area and their spatial distribution.The calculations indicate that the Qibuxi watershed is the primary source of terrestrial contamination for the sea and soil erosion as well as domestic contamination contributes greatly to its pollution. |
