Abstract

This study was investigated to find out the distribution of vascular flora and remarkable plants and its factors and management plan in the forest genetic resource reserve of Mt. Munsu, located in the DMZ and DMZ border area in Gimpo, Gyeonggi-do province. The survey was carried out 17 times from April 2019 to October 2020. First of all, in the forest genetic resource reserve of the Mt. Munsu, a total of 444 taxa in 95 families, 276 genera, 395 species, 13 subspecies, 33 varieties and 3 forms. This result was found to be about 9.09% of the total 4,881 taxa of vascular plants in Korea. In addition, endemic plants were classified as 6 taxa. Floristic special and rare plants were identified as 39 taxa and 3 taxa, respectively. Lastly, the invasive alien plants that appeared in Mt. Munsu of the forest genetic resource reserve were observed in 58 taxa. Moreover, the naturalization rate was 13.1% and the urbanization index was calculated to be 18.0%. As a result of comparing the vascular flora at the forest genetic resource reserve on Mt. Munsu identified in this study with previous studies, it was found the number of taxa was decreased compared to the previous studies, despite the fact that the recent survey section was wider and more varies routes were investigated. In particular, it was confirmed that the number of rare and endemic plants decreased significantly, and the number of invasive plants greatly spread to forest roads and hiking trails. Therefore, it is considered that the forest rest year system should be introduced for the conservation and management of native plants in the forest genetic resource reserve.

본 연구는 경기도 김포의 최서북단 DMZ 접경지역 및 민북지역에 위치한 문수산의 산림유전자원보호구역 일대의 관속식물상과 침입외래식물 등을 파악하고 확인된 식물들의 효율적인 관리와 생물다양성 보전을 위한 기초자료로 활용하기 위하여 실시하였다. 조사는 2019년 4월부터 2020년 10월까지 총 17회에 걸쳐 실시되었다. 문수산 산림유전자원보호구역 일대의 관속식물상은 총 95과 276속 395종 13아종 33변종 3품종 444분류군이 분포하는 것으로 확인되었다. 이는 우리나라 관속식물 총 4,881분류군의 약 9.09%로 나타났다. 문수산 산림유전자원보호구역에서 출현한 한반도 특산식물은 은사시나무, 오동나무, 산이스라지, 백운산운추리 등 6종이 관찰되었다. IUCN 지정 희귀식물은 총 3분류군이 관찰되었다. 위기종(EN)은 복사앵도나무, 약관심종은 쥐방울덩굴과 창포가 출현하였다. 식물구계학적 특정식물은 초 39분류군으로 파악되었다. IV등급은 바위말발도리 등 2분류군, III등급은 고광나무, 병아리꽃나무 등 8분류군이 확인되었다. II등급은 잣나무 및 오리나무 등 총 10분류군이 관찰되었다. 조사지역에서 출현한 침입외래식물은 개망초, 달맞이꽃 및 개쑥갓 등 58분류군으로 확인되었다. 귀화율은 13.1%로 나타났으며, 도시화지수는 18.0%로 계산되었다. 본 연구에서 파악된 문수산 산림유전자원보호구역의 관속식물상과 선행연구와 비교한 결과, 최근 조사 구간이 더 넓고 다양한 경로를 조사했음에도 불구하고 선행연구에 비해 분류군 수가 감소한 것으로 파악되었다. 특히 희귀·특산식물의 수는 크게 감소하고 외래침입식물의 수는 임도 및 등산로 등으로 크게 확산한 것으로 확인되었다. 따라서 산림유전자원보호구역 내 자생식물의 보전 및 관리를 위해 산림휴식년제 등을 도입해야 할 것으로 생각된다.
