| In order to elucidate the budget and cycling of Nitrogen and Sulfur, essential elements and principal constituents of acid rain, their input through precipitation, and their output by streamflow were quantified in coniferous and deciduous forested watersheds, using combination of nutrient concentration and hydrological analysis, in Kwangnung Experimental Forest from July 1991 to December 1993. Amount of annual mean precipitation was $12,916;ton{cdot}ha^{-1}{cdot}yr^{-1}$, annual mean runoff $5,094;ton{cdot}ha^{-1}{cdot}yr^{-1}$(39%), $7,467;ton{cdot}ha^{-1}{cdot}yr^{-1}$(59%) in coniferous and deciduous forest watersheds, respectively. Amounts of annual input of $N({NO_3}^-+{NH_4}^+)$ and ${SO_4}^{2-}$ through preciptation were 12.5, $81.72;kg{cdot}ha^{-1}{cdot}yr^{-1}$, repectively. Annual output via runoff of $N({NO_3}^-+{NH_4}^+)$ and ${SO_4}^{2-}$ were 0.06, $39.23;ton{cdot}ha^{-1}{cdot}yr^{-1}$ in the coniferous forest watershed ecosystem, and 0.15, $55.46;ton{cdot}ha^{-1}{cdot}yr^{-1}$ in the deciduous one, respectively. On the basis of annual nutrient input and output, the annual budget of $N({NO_3}^-+{NH_4}^+)$ and ${SO_4}^{2-}$ were +12.46, $+42.49;ton{cdot}ha^{-1}{cdot}yr^{-1}$ in the coniferous forest watershed, and +11.35, $+26.26;ton{cdot}ha^{-1}{cdot}yr^{-1}$ in the deciduous one. Thus $N({NO_3}^-+{NH_4}^+)$ and ${SO_4}^{2-}$ were accumulated in both forested watershed ecosystems. |
