This research was conducted to establish the conservation strategy of stream water quality by analyzing the factors influenced on stream water quality in the northeastern part of Mt. Bughansan National Park from July 1998 to October 2001. The number of visitors resulted in the significant increase of electrical conductivity, which affected on pollution of the stream water quality. According to the multiple regression analysis, the pH of the stream water was related to dissolved oxygen and temperature of water at the 1% significant level. The electrical conductivity of the stream water was related to number of visitors, amount of $K^+$ and ${NO_3}^-$, total amount of ions, percentages of $Cl^-$ and $Na^+$ caused by solifluction soil at the 1% significant level. The anions($Cl^-$, ${NO_3}^-$ and ${SO_4}^{2-}$) of the stream water were related to number of visitors, electrical conductivity, air temperature, hardness, amount of ${NO_3}^-$, ${SO_4}^{2-}$, total ions, percentage of $Cl^-$, ${NO_3}^-$, ${SO_4}^{2-}$, amount of $Ca^{2+}$ caused by solifluction soil at the 1% significant level. To prevent the pollution of stream water in the northeastern part of Mt. Bughansan National Park, it is recommended that the number of visitors in the park should be managed and rehabilitated rapidly by measure to eco-friendly during the spring season.

본 연구는 북한산국립공원 북동사면 일대에서 계류수질에 미치는 동결융해침식토사의 영향을 파악함으로써 국립공원내 계류수질 보전을 위한 과학적 기초 자료를 제공하기 위하여 2002년 3월부터 5월까지 수행하였다. 조사기간 동안 계류수의 평균 pH는 동결융해침식토사의 평균 pH보다 높았으며, 계류수의 평균 전기전도도는 상류유역이 하류유역보다 약 2.1${\sim}$2.8배 낮은 값을 나타내었다. 또한, 직선회귀분석결과 동결융해침식된 토사와 계류수에서의 pH와 음이온량 ($Cl^-,\;N0_3\;^-, So_4\;^{2-}$)은 정의 상관관계를 나타내었다.

A questionnaire survey from 200 visitors and 100 residents was carried out to establish the management plan of the artificial structures constructed in valley within Bughansan National Park. According to the result of the survey respondents realized that the valley ecosystem could be damaged by artificial structures, but not pollutants of stream water. About 60 % of the respondents felt uncomfortable by artificial cement constructures and about 22 % was concerned about negative effect of valley ecosystem by the constructures. The results categorized by management body, management system and management cost indicate that the artificial constructures should be managed in terms of the safety and conservation of valley ecosystem.

This research was conducted to investigate the influences caused by solifluction soil on the physicochemistry of stream water quality at the riparian area four points in the northeastern part of the Bughansan National Park from March to May of 2001. The average pH of stream water was higher than those in the caused by solifluction soil. The average electrical conductivity of upstream water was about 0.8~1.7 times lower than those in the caused by solifluction soil, but the average electrical conductivity of downstream water was about 1.6~3.8 times higher than those in the caused by solifluction soil. Therefore, these results showed that the water quality of downstream was worse than that of upstream. Twelve factors including the physicochemistry on the stream water and caused by solifluction soil were analyzed by spss/pc+ for the data collected from during March to May of 2001. pH of stream water was very significantly correlated with pH and electrical conductivity at the caused by solifluction soil. And the electrical conductivity of stream water was very significantly correlated with electrical conductivity and the amount of cation($Na^+$, ${NH_4}^+$, $Mg^{2+}$) at the caused by solifluction soil.

Questionnaire survey from 101 visitors and 77 specialists was carried out to establish the management plan on landscapes of the artificial structure constructed in valley within Bughansan National Park. When comparison was made between ground sill work structure and valley landscape, visitor group responded to the highest scores in valley landscape after planting of vine species in the bottom of the constructure, while specialist group responded to valley landscape after the removal of the constructure. When it made a comparison between revetment work constructure and valley landscape, visitor group responded to highest scores in valley landscape after planting of vine species in the top of the constructure, while specialist group responded to valley landscape after replacing concrete revetment by stone revetment constructure. When it made a comparison between fall work constructure and valley landscape, both groups responded to the highest scores in valley landscape after the removal of the constructure. According to the valley landscape analysis, artificial constructures built in water channel should be matched to adjacent landscape with the removal of concrete constructure. The slope of water channel should be considered to build fall work constructure.
