Abstract

This study was carried out to investigate the flora of the western front (Paju-Yencheon Area) of the Civilian Control Zone. Vascular plants collected in these areas were a total of 558 taxa composing of 501 species, 3 subspecies, 48 varieties and 1 forma of 330 genera under 109 families This shows that 11% of the 4,880 vascular plant species that are known to exist in Korea is distributed in the western part of the DMZ. 1 taxa of endangered species designated by the Ministry of Environment was found: the Polygonatum stenophyllum Maxim in the edge of the military operation road from Taepung observatory to Imjin river. For the floristically specific ones of the Korean floristic zones, 3 taxa of the $5^{th}$ grade, 3 taxa of the $4^{th}$ grade, 13 taxa of the $3^{rd}$ grade, 13 taxa of the $2^{nd}$ grade and 22 taxa of the $1^{st}$ grade were found. For the endemic species of Korea, 4 taxa including Cirsium setidens (Dunn) Nakai were confirmed to be distributed mostly on the slope or the cutting area. Among the collected rare plants (11 taxa), there were 1 taxa of endangered species, 4 taxa of vulnerable species and 6 taxa of least concern species. Also, 51 taxa of naturalized plants were identified and 4 taxa of ecosystem disturbance organism designated by the Ministry of Environment were identified. The urbanization index and naturalization index for all species were estimated to be 15.89% and 9.14% respectively. Our survey is expected to be considered as primary data of biological diversity and ecological axis in the DMZ and the western part of the DMZ. According to the results of this study, it is thought to be necessary to establish policies for conservation and protection of the DMZ.

본 연구는 민간인출입통제구역 서부전선(파주-연천) 일대의 식물상을 파악하기 위하여 현지조사를 실시하였다. 확증표본을 근거로 한 민통선 이북 서부지역의 관속식물은 109과 330속 501종 8아종 48변종 1품종의 총 558분류군으로 확인되었다. 한반도에 분포하는 식물종은 최근에 유입된 귀화식물을 비롯하여 약 4,880여종의 식물이 보고되었으며 한반도 전체 식물의 약 11% 정도가 민통선 이북 서부지역 일대에 분포하는 것으로 나타났다. 환경부 지정 멸종위기야생생물은 II급 층층둥굴레 1분류군이 확인되었으며, 태풍전망대에서 임진강에 이르는 군작전로 가장자리에 3개체가 생육하였다. 식물구계학적 특정식물은 V등급 3분류군, IV등급 3분류군, III등급 13분류군, II등급 13분류군, I등급 22분류군으로 구성되었다. 한반도 고유식물은 고려엉겅퀴 등 4분류군으로 나타났으며, 대부분 숲 절개지 또는 숲 가장자리에 분포하였다. 희귀식물은 위기종(EN) 층층둥굴레 1분류군, 취약종(VU) 느리미고사리 등 4분류군, 약관심종(LC) 쥐방울덩굴 등 6분류군으로 총 11분류군이 확인되었다. 귀화식물은 총 51분류군으로 귀하율은 9.14%, 도시화지수는 15.89%로 산출되었으며 환경부지정 생태계교란식물은 단풍잎돼지풀 등 4분류군이 확인되었다. 본 연구는 DMZ 생태축의 서부지역 식물상 연구를 수행하고 주요 식물의 분포 양상과 보존대책을 위한 기초자료를 제공하고자 하였다.
