Abstract

Ecological restoration is an eco-technology, which heals the nature damaged by human activity by imitating organization and function of the integrate nature and thereby provide an inhabitable space for diverse organisms. Such an ecological restoration has to be carried out by applying restoration plan prepared based on the results of diagnostic evaluation discussed in the diversified respects. This study aims to prepare an ecological restoration plan of the damaged forest ecosystem in Mt. Moodeung National Park. To arrive at the goal, first of all, we diagnosed quality of forest landscape established in Mt. Moodeung National Park based on natural (topography, climate, and distribution of vegetation) and artificial (land use, linear landscape element) factors. In addition, we evaluated the integrity of each zone divided by linear landscape element quantitatively based on geometric property and land use intensity. As the result of analysis, topography of Mt. Moodeung National Park tended to be depended on weathering property of parent rock and vegetation zones were divided to three vegetation zones. Based on land use pattern, deciduous broad-leaved forest, evergreen needle-leaved forest, and mixed forest occupied about 90% of Mt. Moodeung National Park. Mean score of forest landscape quality was shown in $69.86{\pm}11.41$. As a result, forest landscape elements in Mt. Moodeung National Park were influenced greatly by human activity and the degree was depended on topographic condition. This study suggested the synthetic restoration plan to improve ecological quality of Mt. Moodeung National Park based on the results of diagnostic evaluation.

생태적 복원은 온전한 자연의 체계와 기능을 모방하여 인간이 훼손시킨 자연을 치유함으로써 다양한 생물들에게 서식공간을 제공하고 인류의 미래 환경을 확보하기 위한 생태기술이다. 이러한 생태적 복원은 복원대상에 대한 다각적 측면의 진단평가 결과에 근거하여 수립된 복원 가이드라인에 따라 수행되어야 한다. 본 연구에서는 무등산국립공원의 훼손된 산림의 생태적 질을 평가하고, 이를 회복시키기 위한 경관수준의 복원 가이드라인을 수립하였다. 이를 위해, 우선 자연적 요소(지형, 기후, 식생 분포)와 인위적 요소(토지이용, 선형 경관요소의 분포)를 고려하여 무등산국립공원에 성립해 있는 산림의 생태적 질을 진단하였다. 이와 더불어, 선형 경관요소에 의해 구획된 각 권역의 기하학적 속성 및 토지이용 강도에 근거하여 온전성 정도를 평가한 후 이를 점수화하였다. 분석 결과, 무등산국립공원의 거시적 지형은 모암의 풍화 특성에 의해 결정되는 양상이었으며, 식생대는 해발고도의 수직적 구배에 따라 난온대상록활엽수림대, 난온대낙엽활엽수림대 및 냉온대낙엽활엽수림대로 구분되었다. 토지이용유형에서 무등산국립공원은 활엽수림, 침엽수림 및 혼합림이 전체의 약 90%를 차지하였다. 경관파편화를 유발하는 경관요소로서 탐방로는 총 97개소로 파악되었다. 경관의 질 점수는 평균 $69.86{\pm}11.41$로 나타났다. 진단평가 결과, 무등산국립공원 내 산림의 생태적 질은 인간활동의 영향을 크게 받았고, 그 영향 정도는 지형에 따라 다르게 나타났다. 한편, 무등산국립공원은 산 중심으로 설정된 국립공원 경계와 모암의 풍화 특성에 의해 공원구역 내 수공간이 부족한 것으로 파악되어 이러한 문제를 해결하기 위해 주변 지역과의 생태네트웍 구축이 필요한 것으로 판단되었다. 본 연구에서는 이러한 진단평가 결과에 바탕을 두고 무등산국립공원의 생태적 질을 향상시키기 위한 복원 가이드라인을 제시하였다.
