This study is intended to evaluate the value of functional aspect from the viewpoint of habitat. The indicators that are used in biotope evaluations are various, but most of them use the criteria to evaluate the naturality. This evaluation method cannot appropriately reflect the functional characteristics coming from relation to the surrounding biotope. In this study, the connectivity, cohesion and diversity between individual biotope are quantitatively measured by a landscape index. It is hard to draw the functional value of individual biotopes because the landscape index related to connectivity, cohesion and diversity comes from a landscape having a number of biotopes. The concept of contribution was used to overcome this limitation. The concept of contribution is to quantify how much each individual biotope contributes to the connectivity, cohesion, and diversity in a certain range of landscape by deriving the amount of change in the landscape index according to the presence or absence of each individual biotope. In order to understand the characteristics of evaluation results in functional aspect, this research has done a comparative analysis of the previous research findings in the same target area. According to the result of the research, individual biotopes such as artificial forests, fragmented natural forests, and small planting sites were highly rated.

본 연구는 효율적 비오톱평가를 위해 일반적으로 적용할 수 있는 평가항목 및 평가체계를 개발하고자 하였다. 이를 위해 지금까지 선행된 연구사례들을 비교 검토하여, 현실적 적용가능성이 높은 비오톱 평가 항목 및 평가체계(안)을 도출하고, 선정된 사례지역의 적용과 자문회의 등의 계속적인 피드백 과정을 통하여 효율적인 비오톱평가를 위한 평가항목 및 평가체계를 제안하였다. 첫째, 비오톱평가를 위한 항목으로는 자연성 및 헤메로비, 다양성, 면적, 고립성 및 연결성, 복원능력, 희귀성 등 6개 항목을 제안하였다. 둘째, 비오톱 평가체계는 1단계 평가인 전체 비오톱유형에 대한 평가와 2단계 평가인 개별 비오톱에 대한 생태적 보전가치평가로 구분한다. 유형평가단계에서는 자연성 및 헤메로 비와 다양성 항목을 중심으로 평가하고, 개별평가단계에서는 고립성 및 연결성, 복원능력, 희귀성 등과 같은 항목을 중심으로 평가할 것을 제안하였다. 그러나 비오톱평가는 지역의 특성이 고려되어야 하므로, 본 연구에서 제안된 평가항목 및 체계를 기반으로 하여 지역의 상황과 여건에 맞는 평가항목 및 지표들을 충분히 검토하여 선택하고 필요시 세부평가지표들이 추가 보완되어야 할 것이다.

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.
