Abstract

Recently mountain tourism has been promoted and introduction of railroads with utilizing mountain resources is being planned. With the government policies to increase the share of eco-friendly transportation on railroad, national double-tracking of single rail and improvement projects are on going. However, the eco-friendly railroad policy suggests the environmental impact assessment items only on air quality, water quality, geographical/geological features, fauna/flora, natural/environmental resources, noise/ vibration, and recreation/landscape. And for fauna/flora and natural/environmental resources, confirming the presence of environmental protection zone is enough to satisfy legal requirement. This study suggested to evaluate environmental/ecological values with quantitative data. Evaluation indices and evaluation items have been selected to provide the data. Each of the subject map and railroad network was overlapped. The study selected naturalness and diversity as major indicators and calculated weight values of the items under the indicators, which are to be usd for the selection of the sites for railway development. This assessment method could be applied to the environmentally friendly construction of railroads in the future.

최근 국토의 산악자원을 활용한 철도를 도입하는 등 산악관광 활성화를 도모하려는 움직임이 나타나고 있으며, 친환경 교통수단으로의 철도수송 분담률을 증대시키려는 정책이 수행됨에 따라 단선철도의 복선화 및 선형개량 사업 등 전국 철도망이 확대되고 있는 추세이다. 그러나 "환경친화적 철도지침"에 따르면, 철도건설 시 고려해야 할 주요 환경영향평가항목으로 대기질, 수질, 지형 지질, 동 식물상, 자연환경자산, 소음 진동, 위락 경관 등 7개 항목을 선언적으로만 제시하고 있으며, 특히 동 식물상과 자연환경자산 항목에서는 법제적 측면에서 환경보호지역의 유무만을 고려하고 있다. 이에 따라 본 연구에서는 환경 생태적 가치를 정량적 평가항목으로 고려할 것을 제안하였고, 이를 계량적으로 뒷받침하기 위해 평가 지표와 평가 항목을 선정하고 각각의 주제도와 철도망을 중첩하여 분석하였다. 주요 지표로 자연성과 다양성을 선정하였고, 각 지표별 항목의 평점을 산정하여 철도개발지 선정에 반영하고자 하였다. 이와 같은 평가 방법을 활용하여 추후 환경친화적인 철도건설에 적용할 수 있을 것으로 판단된다.
