Abstract

Studies on effects of human action on the destruction of ecosystems and changes in biodiversity are being processed actively from the view point of landscape ecology. This study investigated present distribution status of the naturalization plant by disturbance of natural ecosystem which could be seen on 35 rural villages in Korea. The study made a landuse map on the study area then quantified the landscape ecologic characteristic using landscape index based on this landuse map. Correlation between landscape index on the study area and distribution characteristic of naturalization plant was analyzed. The landscape index was calculated by FRAGSTATS, a spatial analysis program, and naturalization index and urbanization index were used in the distribution characteristic of naturalization plant. As a result, naturalization index and patch density, naturalization index and edge density, naturalization index and area-weighted mean shape index were shown as having positive correlation, and naturalization and core area percentage of landscape, naturalization index and mean core area were displayed as having negative correlation.

인간 활동이 생태계의 훼손과 생물다양성의 변화에 미치는 영향을 경관생태학적 측면에서 분석하고 해석하는 연구가 활발히 진행되고 있다. 본 연구는 우리나라의 35개 농촌마을을 대상으로 자연생태계의 교란정도를 알 수 있는 귀화식물분포현황을 조사하였다. 대상지에 대한 토지이용 현황도를 제작하고 이를 바탕으로 경관지수를 이용하여 경관생태학적특성을 정량화하였다. 이를 바탕으로 대상지의 경관지수와 귀화식물 분포특성의 상관관계를 분석하였다. 경관지수는 공간분석 프로그램인 FRAGSTATS를 이용하여 산출하였으며 귀화식물의 분포특성은 Urbanization Index와 Naturalization Index를 이용하였다. 연구 결과 귀화율과 패치밀도, 귀화율과 가장자리밀도, 귀화율과 면적가중평균형태지수 등이 양의 상관관계를 나타냈으며 귀화율과 핵심면적백분율, 귀화율과 평균핵심지역 등이 음의 상관관계가 있는 것으로 분석되었다.
