초록

본 연구는 선택되어진 지뢰지역과 습지조각의 산림성조류의 군집에 대하여 경관생태학적 가치를 평가하도록 하였다. 각각 면적이 다른 세 곳(8.5ha, 17.4ha, 40.6ha)의 지뢰지역과 산지지역의 세 개 비교지역의 조류상분석을 이용하여 평가하였다. 평균 산림성조류의 종수, 개체수, 종다양성, 종풍부도와 종균등도를 조각의 크기와 습지의 존재와 연결성과 같은 환경적 특성에 의하여 분석하였다. 군집 유사도지수는 실험군과 대조군 조사구사이를 비교하였다. 조류군집은 다음과 같이 요약되었다. 첫째, 63종의 조류가 조사되었으며, 최대개체수 합계는 828개체였다. 종다양성지수는 3.8이었으며, 종풍부도는 9.2, 종균등도는 93.3 이었다. 둘째, 작고 숲과 고립된 숲은 낮은 평균 종의 수와 개체수를 가졌지만, 소하천을 가진 작은 숲 조각은 개활수면이 없는 숲 조각에 비하여 높은 조류 밀도를 보였다. 셋째, 갈대습지를 가진 숲 조각은 단위면적당 조류 종의 수(/10ha), 단위면적당 개체수, 종다양도지수, 종풍부도와 종균등도에서 낮은 가치를 가진 것으로 평가되었다. 마지막으로, 군집 유사도지수는 소하천을 가진 작은 숲 조각은 다른 숲과 연결되어 있는 큰 산지 숲과 유사성이 높게 나타났다. 결과적으로, 저지대 숲 조각은 작은 면적에도 불구하고 다른 서식지와 연결되고 서식지가 넓은 산지의 숲 조각과 군집유사도가 비슷하였다. 따라서, 하천숲의 복원은 산림성조류의 군집에서 생물다양성을 향상시킬 것으로 제안한다.

We evaluated the landscape ecological value of selected minefields and wetland patches as a habitat of the forest bird community. The avian fauna of three minefields of 8.5ha, 17.4ha, and 40.6ha were evaluated by comparing that of three control sites of mountain area. Average number of forest bird species, number of individuals, species diversity index, species richness, and species evenness were analyzed according to the size of patch and environmental characteristics such as the presence of wetland and connectivity. Community similarity was evaluated between test and control plots. Avian fauna can be summarized as follows. First, 63 species were recorded, and the sum of maximum counts was 828 individuals. Species diversity index was 3.8, and the species richness was 9.2. Species evenness was 93.3. Second, small, isolated forest patch had a low average number of species and individuals as expected. But, small forest patches with streams had higher bird density than patches without water surface. Third, forest patches with marsh wetland were evaluated as lower habitat quality than forest patches with stream wetland in terms of the number of bird species per unit area, number of individuals per unit area, species diversity index, species richness index, and species evenness. Finally, Community similarity of the small forest patches with streams was similar with large connected forest. As a result, lowland forest patch was shown the good quality for the forest bird community in spite of small extents, and community structure was similar with mountain forest bird community. Thus, riparian forest restoration could improve the biodiversity of the forest bird community.
