  • This research was conducted to investigate the physicochemical characteristics of stream water at the four points in the northeastern part of Puk'ansan National Park from July, 1998 to November, 1999. The average pH of stream water was 6.65 and dissolved oxygen was $10.7mg/{\ell}$, which indicated that the quality could be categorized in the first class for the quality of river water quality standard. In addition, the water was soft water and average percentage of dissolved oxygen was 96.7%, which was almost saturated. The number of visitors resulted in the increase of dissolved ion, witch affected on electrical conductivity of the water. The relationships between those factors was significant at the 1% level in linear regression. The electrical conductivity and the amount of anion($Cl^-$, $NO{_3}^-$, $SO{_4}^{2-}$)in downstream were higher than those in upstream.
