Abstract

The purpose of this study is to assess the recovery rate of vegetation structure after restoration works at the damaged Nogodan area in Jirisan National Park. Fourteen monitoring plots were set up at restoring work area and twelve control plots were set up at natural forest near monitoring plots. Flora, Relative Importance Percentage and Similarity Index were analyzed. Mean Similarity Index between monitering plot and control plot near helliport area showed thirty five point two percent and height of shrub layer recovered up to twenty percent, approxomately durindg twenty three years after experimental restoration works. Mean Similarity Index between monitering plot and control plot around Nogodan peak area showed seventeen point six percent but height of shrub layer recovered up to twenty percent, approxomately during ninteen years after restoration works. Mean similarity index between monitering plot and control plot on transfered millitary area showed thirty four point three percent but coverage of shrub layer showed twenty percent,approxomately during seven years after restoration works. Long term monitering shall be necessary for developing assessment criteria of ecologial restoration and ecological restoration technology.

본 연구의 목적은 식생복원사업후 경과년수에 따라 지리산국립공원 노고단일원의 식생구조의 회복수준을 평가하는 데 있다. 1992년(23년 전)에 시행한 헬기장 주변 훼손지 복원연구 시험지역, 1996년(19년 전)에 시행한 노고단 정상부 훼손지 복원사업지역, 2008년(7년전)에 시행한 군시설 이전지 복원사업지역에 모니터링 시험구 14개소, 복원지 인근 자연림에 대조구 12개소등 총 26개소의 조사구를 설치하여 복원사업지와 인근 자연림간 식물상, 상대우점치, 종다양도, 유사도지수 등을 분석하여 식생회복 정도를 평가하였다. 23년이 경과된 훼손지복원시험지역은 시험구와 대조구 간 종구성의 유사도지수 평균치가 35.2%이었고, 관목층 수고는 20% 수준으로 회복되었다. 19년이 경과된 정상부 식생복원사업지역은 종구성의 유사도지수 평균치가 17.6%로서 상대적으로 낮았으나, 털진달래가 출현하는 관목층의 수고는 20%의 수준으로 회복되었다. 7년이 경과된 군시설이전지역의 유사도지수는 34.3%로 비교적 높았으며, 관목층의 피복도는 대조구의 20% 수준을 나타냈다. 국립공원지역의 생태복원평가기법과 생태복원기술개발을 위하여 복원사업지역에 대한 장기모니터링이 필요하다.
