한경 곶자왈 산림유전자원보호구역은 개가시나무와 백서향 등을 포함한 암괴지대의 상록활엽수림으로서 그 중요성이 인정되어 산림유전자원 생태보전지역으로 지정 관리되고 있다. 따라서 본 지역의 식물상을 조사하여 곶자왈의 분포식물을 파악하고자 실시하였다. 본 연구는 한라산 서쪽 곶자왈지역 중 곶자왈 산림유전자원 보호구역으로 지정된 지역을 2017년 6월부터 2017년 9월까지 20여 차례 현장조사를 통하여 표본을 수집하고 이를 기록 정리하였다. 조사지역의 식물은 총 83과 181속 236종 23변종 2품종 총 261종으로 조사결과 양치식물이 7과 18속 30종 2변종 32분류군, 나자식물이 1과 1속 2분류군, 피자식물은 74과 162속 204종 21변종 2품종 227분류군 이었다. 그 중 쌍자엽식물은 67과 139속 179종 16변종 1품종 196분류군이고, 단자엽식물이 7과 23속 25종 5변종 1품종 31분류군이었다. 조사에서 확인된 환경부 멸종위기야생식물은 개가시나무 1종 이었다. 식물 구계학적 특정식물로는 총 97분류군이 조사되었다. 등급별로는 V등급 검정개관중, 개가시나무로 2분류군, IV등급 백서향, 녹나무 등 12분류군, III등급 아왜나무, 호자나무 등 37분류군, II등급 올벚나무, 개산초 등 13분류군, I 등급 푸조나무, 자금우 등 33분류군으로 확인되었다. 한국의 적색목록 식물을 분석해보면 취약(VU)은 개가시나무, 섬다래 등 3분류군, 준위협(NT)은 백서향, 약난초로 2분류군, 관심대상종(LC)은 골고사리, 새우난초 등 9분류군, 미평가종(NE)은 빌레나무 1분류군으로 나타났다. 이 결과는 청수 저지 곶자왈 지역의 생태학적 자료로 제주도 내 곶자왈과 비교하였을 때 맹아가 발달한 종가시나무가 우점하는 지역으로 향후 상록수림 천이에 의해 상록수 아래에 자라는 식물로 낙엽활엽수가 대체될 것으로 추정되어 지속적인 조사가 요구된다.

This study aimed to understand current flora of Western Civilian Control Zone (CCZ) in Korea. Some areas that located at Paju-si and Yeoncheon-gun were selected as representative survey area (Jangdan-myeon, Deokjin mountain fortress, Ilwol peak of Mt. Seokbyeong, Imjinriver, Sunaecheon stream, Sewolcheon stream in Paju and Banjeong-ri in Yeoncheon). Through this survey, 461 vascular plant specimens were collected from April 2012 to September 2014, twice a month and from October 2014 to October 2018, once a month. These were finally classified into 96 families 305 genera 413 species 4 subspecies 41 varieties 6 forms totally 464 taxa. There are remarkable plants such as 6 taxa of Korean endemic species, 44 taxa of specified species on a floristics aspect, and 35 taxa of alien and naturalized plants (7.5%). Meanwhile, it has not been observed any endangered plant species during the activities in this area.
