This research was conducted to analyze the factors influenced on stream water quality pollution in the northeastern part of Puk'ansan National Park from July, 1998 to November, 1999. The number of visitor and the percentage of the amount of $Cl^-$ resulted in the increase of electrical conductivity, which affected on pollution of the stream water quality. The relationships between those factors should be statistical significance at the 5% level in multiple regression. The multiple regression equations for the percentage of dissolved oxygen at the stream water quality showed that dissolved oxygen and water temperature had statistical significance at the 1% level. The multiple regression equations for the amount of $Cl^-$ at the stream water quality showed that electrical conductivity, the amount of cation($K^+$, $Na^+$), the amount of $SO_4{^{2-}}$, total amount of ion, the percentage of the amount of $Cl^-$, and the percentage of the amount of $SO_4{^{2-}}$ had statistical significance at the 5% and 1% level. Also, The multiple regression equations for the amount of $NO_3{^-}$ at the stream water quality showed that the amount of cation($Na^+$, $Ca^{2+}$), the amount of $SO_4{^{2-}}$, the percentage of the amount of $Cl^-$, and the percentage of the amount of $NO_3{^-}$ had statistical significance at the 5% and 1% level. The multiple regression equations for the amount of $SO_4{^{2-}}$ at the stream water quality showed that the amount of $NO_3{^-}$, total amount of ion had statistical significance at the 5% level.
