This study was conducted to develop an environmental index for assessing the vulnerability of areas with invasive alien plants. To that end, "Regional Vulnerability Numerical Index" (RVNI) was developed with a spatial statistical technique and applied to Seoul and Gyeonggi-do area first. The results...

생태계교란식물의 악영향은? | ,1998; CBD, 2008; IUCN, 2011). 특히 생태계교란식물은 다양한 방법에 의한 종자 확산 및 왕성한 영양 번식으로 개체군을 확장하여 고유 생태계를 교란할 뿐 아니라 심할 경우 자생종을 절멸시키며, 꽃가루 등의 알레르기 물질을 발생시키는 등 인간생활에도 악영향을 준다(Gurevitch and Padilla, 2004; Mooney 2005; Pimentel et al.,2005). | |
외래생물이 유입되는 과정은? | 외래생물은 농업용, 조경용, 공업용 등의 목적으로 국내에 유입되며, 국가간 무역의 증가, 해외 여행인구의 증가, 철새의 이동 등 의도치 않은 경로에 의해서도 유입되기도 한다(Pimentel et al., 2001; Perrings et al. | |
지방자치단체에서 실시한 생태계교란생물 제거사업이 효율적이지 못한 이유는? | 이는 소규모단위로 시행되는 생태계교란식물의 확산 대책이 효율적이지 못하다는 것으로 의미한다. 식물은 다양한 방법으로 종자를 확산하는데 소규모지역 단위로 제거 계획을 수립한다 하더라도 외부에서 유입되는 생태계교란식물의 종자 유입을 물리적으로 제어할 방법이 현실적으로 존재하지 않기 때문이다. 최근 생태계교란식물인 가시박의 성장을 물리적으로 억제하는 방법이 연구되고 있지만(Kang, 2014)이 또한 한시적인 방법인 것으로 판단된다. |
