The purpose of this research is to assess potential area of mountainous wetland by GIS and AHP (Analytic Hierarchy Process). Mountainous wetland is topographically located at high altitude, so it's difficult to approach for researchers. And, it's difficult to investigate systematically because of the insufficient information of mountainous wetland. Therefore, it's necessary to study on potential area of mountainous wetland for systematic and efficient investigation. This research selected slope, wetting index, land-cover map and soil map as assessment items indicating environmental characteristics of mountainous wetland and established them by GIS DB. And, spatial value of mountainous wetland for each assessment item was drawn by existing investigation data and overlap analysis of mountainous wetland. Based on the numerical results of each assessment item, a survey was conducted and relative importance for each assessment item was decided by AHP. As the result, slope was the highest as 0.550 and ground coverage was the lowest as 0.083. The subject of this research was Yangsan-si and Ulsan of Gyeongnam and an analysis was conducted for mountainous wetland in those research areas. As the result, all of wetland was distributed in the range of potential area. And, field survey and literature search were conducted for the point that the distribution of mountainous wetland is expected. As the result, mountainous wetland was distributed. Therefore, mountainous wetland should be excavated through the results of this research and it should be helpful for effective investigation as providing information necessary to the following studies on mountainous wetland.

In this study, a digital terrain analysis had been performed for a mountainous watershed having wetlands. In order to consider the impact for wetland in the flow determination algorithm, the Laplace equation is implemented into the upslope accounting algorithm of wetness computation scheme. The computational algorithm of wetland to spatial contribution of downslope area and wetness was also developed to evaluate spatially distributed runoff due to the presence of wetland. Developed schemes were applied to Wangpichun watershed located Chuncuk mountain at Ulzingun, South Korea. Both spatial distribution of wetness and its histogram indicate that the developed scheme provides feasible consideration of wetland impact in spatial hydrologic analysis. The impact of wetland to downslope propagation pattern is also useful to evaluate spatially distributed runoff distribution.

In Korea, many paddy fields in mountainous area have been abandoned because of their low accessibility and rice price and the abandoned paddy terraces have changed into natural lentic wetlands. To understand the relationship between characteristics of environmental conditions and early development of plant community in abandoned paddy terraces, we investigated at four well-maintained abandoned paddy terraces in 3 different climatic zones in Korea. Soil texture of abandoned paddy terraces was mostly kinds of loam and electric conductivity of soil was also similar among abandoned paddy terraces. On the other hand, contents of nitrogen, phosphorus, potassium, sodium, magnesium, and calcium in soil were relatively low and significantly different among abandoned paddy terraces. Water depth was different within sites and inter-sites. Although environmental conditions including climate, soil condition and water depth were different among abandoned paddy terraces, the compositions of plant communities were relatively similar in all abandoned paddy terraces. 55 dominant taxa out of 141 recorded species were commonly recorded over sites and they were mostly perennial obligate wetland plants and facultative wetland plants. 8 taxa out of 55 dominant taxa occurred at all abandoned paddy terraces with over 10% coverage. Several site-specific species occurred at site, which have some area with deep water level. This result indicates that early development of plant community in abandoned paddy terraces of similar water regime is similar in the entire area of Korea even though environmental conditions such as climate, biogeographic history and soil are different.

습지는 교란에 의해 주변 유역으로부터 과잉수, 퇴적물, 영양염, 기타 오염물 등이 축적되는 흡수원으로서 기능하기 때문에 외래종에 의한 생물학적 침입에 취약하다. 본 연구는 내륙습지 유형에 따른 외래식물의 출현현황 및 특성을 파악하기 위하여, 생태우수습지 24개소를 대상으로 유형을 분류하고 외래식물상을 분석하였다. 조사 대상 습지에서 발견된 외래식물은 총 130종으로 출현 식물 총 종수의 11%를 차지하였다. 이 중 국화과가 40종으로 가장 많았으며, 출현빈도가 높은 종은 개망초와 달맞이꽃이었다. 습지 유형별로는 하천형과 호수형 습지에서 평균 30종 내외로 평균 10종 미만인 산지형 습지보다 외래식물 종풍부도가 높은 것으로 나타났다. 인위적인 간섭정도를 나타내는 귀화율, 도시화지수, 일·이년생 비율에서도 동일한 결과가 나타났다. 군집분석에서는 하천형 습지와 호수형 습지가 혼재되었으며, 산지형 습지만 별도로 분리되었다. 산지형 습지는 외래종수가 현저하게 적은 것은 물론 다른 습지 유형에서 발견되지 않은 주걱개망초, 컴프리, 나도닭의덩굴의 영향으로 판단된다. 특히 미국쑥부쟁이, 돼지풀, 가시박, 단풍잎돼지풀 등 생태계교란생물은 하천형 습지에서 집중적으로 발견되었다. 따라서 인위적인 간섭강도가 높은 하천형 및 호수형 습지에서 외래식물 확산 요인을 고려한 체계적인 관리가 시급한 것으로 판단된다.
