The purpose of this research is to evaluate the biotope value in a metropolitan area after constructing the biotope evaluation model to develop biotope networking in the light of ecological landscape planning. In addition this study is to provide a basic frame of constructing the biotope networking system in the future with the evaluation results. The scope of this research is limited to high density residential area including some part of the forest adjacent to urban boundary. The results of the classified biotope in the research area have been turned out to be 24 patterns. According to the result of estimated nature value having the forth grade, three were forests combined with urban natural parks, schools near forests, and grasslands. There is a little place having first grade. We an deduce this fact that we have surveyed biotopes, having the minimum nature value and wider than children's park. As for the result of evaluated the structure, there were the forests of Seong-Dong, Meaho-Dong, and Kumho river, which is the forth grade. As for the evaluation of connection-function, the followings area were evaluated as the third grade-linear biotopes having highly valued and sustainable similarity - Seoul-Pusan Railroad, Dong-Daegu St., Kumho river, river basins. Bum대 park and a botanic park near Suesung lake, As for the evaluated the buffer-function, higly valued production biotopes, existing at a transition belt between he residential density areas, are Sawol-Dong, Meaho-Dong and Kumho river. When each of the indexes was evaluated, the core of the biotop contained most of natural biotopes. Large artificial biotopes were evaluated as an important biotopes, while small artificial biotopes were classified as a dot biotope.

This study aimed to suggest a framework for biotope classification and evaluation based on habitat values to rationally establish management areas of national parks. The factors and indicators related to the biotope classification and evaluation were established based on integration from those of previous studies. The decision tree evaluation process was applied to the classification and evaluation of the biotope type level. The evaluation of the biotope group level was carried out to determine the weight and the AUEM (Adding Up Estimation Matrix) was applied for the final grades. As a result, the biotope type of Seolaksan National Park was classified into 43 types and Odaesan National Park was classified into 41 types. Bukhansan National Park, which is located in a metropolitan city, was classified into 49 types. In terms of biotope evaluation, grade III had a ratio of 50.6%, the highest in Seolaksan national park. The ratios of grade I and grade II, which have great ecological-value, were respectively 12.0% and 36.5%. Grade II was 48.2%, the highest ratio in Odaesan National Park. The ratios of grades I and II were 10.8% and 37.9%, respectively. Grade III was 54.8%, the highest ratio in Bukhansan national park, and the ratios of grade I and grade II, which have great ecological-value were, respectively, 11.4% and 25.7%. The biotope values of major national parks were evaluated according to the type focusing on the actual vegetation. This framework can be considered for application to the spatial management of other types of protected areas.

본 연구는 농촌경관의 잔여경관요소로서 중요한 기능을 수행하고 있는 경작지 내 소규모 습지 및 소하천의 경관생태적 특성 및 가치분석을 토대로 현실적인 개선방안을 제시해 보는데 가장 큰 의의를 두고있다. 연구결과를 요약하면 다음과 같다. 1) 총 7개의 공간에서 출현하고 있는 습지비오톱의 경관생태적 특성분석 결과, 일례로 사례지 5의 경우 수면의 크기가 $10,600m^2$로 비교적 넓게 형성되어 있었으며, 수변의 기울기, 띠숲의 폭, 식생조성상태 등에서 매우 양호한 것으로 평가되었다. 또한 굴곡성은 사례지 8-1에서 주요 돌출부의 수가 2개로 가장 높았으며, 형태적 다양성 역시 1.47로 가장 높은 값을 보였다. 2) 습지비오톱의 문제점 분석 결과, 대부분의 습지들은 여과기능을 수행하기 위한 초본 띠숲의 폭이 1m 내외로 조성상태가 미흡한 것으로 분석되었으며, 특히 사례지 8에서 나타나고 있는 4곳의 습지들은 수변의 기울기가 $45^{\circ}$ 이상으로 사면식생이 생육하기에는 어려움이 있는 것으로 나타났다. 3) 총 6개의 공간에서 출현하고 있는 소하천의 경관 생태적 특성분석 결과, 일례로 사례지 4의 경우 수변 폭은 55m로 가장 넓었으며, 흙, 돌, 자갈 등의 자연재료로 형성되어 있는 것으로 조사되었다. 반면 사례지 2-2의 경우 수변 폭은 4m로 가장 좁았으며, 사면의 경사각은 $90^{\circ}$로 직각의 형태를 이루고 있었다. 또한 식생의 생육이 이루어지고 있지 못한 것으로 나타났던 바, 생태적 가치는 매우 낮은 것으로 평가되었다. 4) 소하천의 문제점 분석 결과, 사례지 2-1은 수변 띠숲의 폭이 5m 정도로 수변 폭에 비해 매우 좁았으며, 주변 경작지로부터 유해 화학물질이 여과없이 방류되고 있었다. 또한 사례지 2-2는 전구간이 콘크리트 포장면으로 형성되어 있으며, 직선적인 하천구조로 인해 자연정화 능력, 홍수방지, 생물서식공간 확보의 측면에서 그 기능이 매우 미약한 것으로 분석되었다. 5) 이상과 같은 경관생태적 특성분석, 문제점 분석 결과를 토대로, 습지의 경우 크게 형상, 식생, 지형구 조적 측면에서, 소하천의 경우 크게 종단구조, 횡단구조적 측면에서 주요 개선방안을 설정하였다. 본 연구의 결과는 최근 농촌지역의 대규모 개발사업, 농지정리사업 및 도로건설 등에서 야기되는 습지및 소하천의 훼손을 방지할 수 있는 기초자료를 제공해 줄 수 있을 것을 판단되며, 또한 이들의 추가조성을 위한 가이드라인을 제시해 줄 수 있을 것으로 사료된다. 그러나 본 연구의 결과를 타 지역으로 확대 적용해 나가기 위해서는 무엇보다 다양한 사례연구를 통한 객관화된 모형개발 및 검증이 뒷받침되어야 할 것으로 생각된다.
