This study has been carried out for the purpose of predicting the potential habitat sites of invasive alien plants in the DMZ and providing the basic data for decision-making in managing the future DMZ natural environment. From 2007 to 2015, this study collected the data for the advent of Ambrosia t...

종분포모형이란? | 학계에서는 DMZ와 같이 현장조사가 불가능하거나 광범위한 지역을 대상으로 한 연구에 종분포모형(Species distribution models, SDMs)을주로 사용하고 있다(Elith and Leathwick, 2009).종분포모형은 생물종의 출현위치와 서식지 환경요소를 통계적으로 분석하여 잠재적인 서식지를 예측할 수 있는 도구이다(Franklin, 2010).그러나 종분포모형의 입력자료인 공간변수가생물종의 서식지 특성을 명확히 반영하지 않을경우 서식지 예측이 과적용(Over-fit)되며 모형의 불확실성(Uncertainty)은 관련 연구에 걸림돌이 되어왔다(Elith and Leathwick, 2009; Park, 2016). | |
DMZ 생태계 보전 및 관리의 한계점은? | DMZ 생태평화공원조성 등 향후 DMZ 생태계 보전 및 관리를 위해서는 DMZ 지역에서의 생태계교란생물에 대한 분포현황 및 예측이 필수적이라 할 수 있다. 그러나 민간인 출입제한과 지뢰 매설지역(Kam and Kim, 2008)으로 인해 DMZ의 현장조사는극히 제한적으로 이루어지고 있기 때문에 현재까지 관련 정보를 활용한 정책 및 제도의 개발은 제한적인 실정이다. | |
생태교란이 주로 발생하는 원인은? | D’Antonio et al.(2004)와 Forman and Alexander(1998)는 DMZ와 같이 사람의 출입의거의 없는 지역에서 발생되는 생태교란은 생태계 교란생물과 같은 외래종 유입에 의해 주로 발생한다고 보고한 바 있다. DMZ 생태평화공원조성 등 향후 DMZ 생태계 보전 및 관리를 위해서는 DMZ 지역에서의 생태계교란생물에 대한 분포현황 및 예측이 필수적이라 할 수 있다. |
