고리도롱뇽의 대체서식지 조성 평가 연구

Abstract

최근 산업의 개발로 인하여 자연환경을 무분별하게 이용해왔고 그 결과 21세기에 이르러 자연의 파괴상황은 더 이상 방치될 수 없는 실정에 이르렀으며, 이러한 변화에 대책으로 보전과 보호방안 수립, 대체서식지나 습지조성 등이 이루어지고 있다. 특히나 습지에 대한 중요성과 이를 통한 생물서식공간이 많이 시도되고 있다. 그 하나의 예로 본 연구대상지인 부산시 기장군 효암리에 위치한 고리도롱뇽 대체서식지를 살펴보면, 원전부지개발로 인해 고리도롱뇽의 서식지가 훼손됨에 따라 대체서식지를 2006년에 조성하였으며, 추가적으로 모니터링을 진행하여 왔다. 허나, 복원이나 대체서식지의 조성의 주목적은 서식지 조기안정화를 유도하고 장기적으로 대체서식지내 복원의 극대화와 생물의 다양성을 높이는 것이며, 이를 위해 몇 가지를 제시하였다. 본 연구대상지에서 고리도롱뇽 대체서식지를 분석한 결과, 우선적으로 대체서식지내 고리도롱뇽의 개체수가 증감이 일어나지 않는다는 것은 복원의 극대화의 차원에서 생물다양성이 미흡한 것으로 판단되며, 서식지내에 식물식재(버드나무, 오리나무 등)를 통하여, 다양한 그늘과 은폐지를 추가 조성하고 수환경을 늘려줌으로써 지역적인 수온차이를 만들어 관리가 이루어져야 할 것이다. 서식지내 다양한 물의 흐름이 미약하나마 흐르는 형태를 가지도록 인위적으로 조성하여, 먹이원의 다양성을 증진시키고, 대체서식지내에 서식이 가능한 종의 이입이 조금 더 이루어지도록 보완하였으면 좋을 것으로 판단된다.

본 연구에 대한 효과는 새롭게 조성된 대체서식지나 복원지역에 실질적인 모니터링방법을 제안하므로써, 원래의 목적인 훼손지역의 재구성과 종다양성의 안정화가 주목적인 복원지역이나, 대체서식지 조성지역 또는 보전을 위한 습지조성지역 등에 적용이 가능할 것으로 판단된다.|Due the recent industrial development, natural environment have been relentlessly exploited, and then the destruction of natural environment has finally reach the impatient level in the 21stcentury. For this problem, the creation and preservation of substitute habitats and wetlands have been made. Especially, the importance of wetlands for habitats is growing. For an example, the author examined the habitats for Hynobius yangi in Hyoam-ri, Kijang-gun, Pusan, which is our research sample area. Due to the development of the site for nuclear power plants, its habitats were destructed, and then restored back in 2006. The author has monitored additionally. The primary purpose of restoring habitats or creating its substitute is to induce the early stability of habitats and to improve the diversity of creatures in a long-term. For this purpose, the author provides some suggestions.. As the result of analysis, first of all, that the volume of Hynobius yangi does not increase in the substitute habitats does not means the success of maximizing the diversity of creatures in the area. Thus, through planting, for example, willow and aider trees, various shades and hideouts are to be additionally created. And increasing water environment will be helpful in management by the creation of difference in temperature. By artificially making the water within habitats even a little flow, the food resources can be diversified and the incoming of the different species that can live in habitats is expected. The impact of this study is for the outcomes to apply to the creation and preservation of wetlands for substitute habitats and restored areas for the purpose of the diversity of species and the restructuring of destructed areas by suggesting monitoring methods in restored and substitute habitats.
