Abstract

The naturalized plant species in Gyeongju National Park was summarized as 46 taxa including 14 families 40 genus 45 species 1 varieties. Among them, annual herbaceous species was 17 taxa (37%) which is grouped as the biggest proportion and 16 taxa (34.8%) for perennial herbaceous species and 11 taxa (23.9%) for biannual herbaceous species and 2 taxa(4.3%) for tree species. European origin was the biggest proportion as 17 taxa (37%), and 16% (34.8%) from North America. The degree of naturalization (DoN) was the biggest for Degree III, V as 18 taxa (39.1%). Regarding 321 naturalized plant species, the Urbanization Index in the studied area was 14.3%. The Namsam District showed 8.1% which is the highest DoN in the studied districts within the Gyeongju National Park. As the cultural properties is important in the Gyeongju National Park as a representatives for historical sites in Korea, planting and its management in the cultural properties is important tasks. The naturalized plant species in the studied area should be reasonably management.

경주국립공원 문화재지정구역에 분포하는 귀화식물은 총 14과 40속 45종 1변종 등 총 46분류군을 확인하였다. 귀화식물을 유형별로 구별해보면, 생활형은 1년생 초본이 17분류군(37%)으로 가장 많았으며, 다년생 초본이 16분류군(34.8%), 2년생 초본이 11분류군(23.9%), 목본이 2분류군(4.3%)로 나타났다. 원산지별로는 유럽이 17분류군(37%)으로 가장 많았으며, 그 다음으로 북아메리카에서 이입된 종이 16분류군(34.8%)으로 나타났다. 또한 귀화도는 3등급이 18분류군(40.9%)으로 가장 높다. 귀화식물 321분류군에 대한 본 연구대상지의 도시화지수는 14.3%이며, 지구별 도시화 지수는 남산지구가 8.1%로 가장 높다. 경주국립공원은 사적형 공원으로 문화재가 매우 중요하나, 문화재 주변의 식재 및 관리 또한 중요하다. 따라서 귀화식물의 경우 장기적인 모니터링과 생태적인 특성을 파악하여 체계적인 관리방안이 요구된다.
