초록

2006년 자연환경보전법 개정에 따라 자연경관심의 제도가 도입되었다. 자연경관심의제도는 자연경관 내 개발사업 및 개발계획 시행 시 사업의 규모와 형태 배치로 인한 스카이라인과 경관보전, 경관자원, 조망축 등의 항목을 검토하는 제도이다. 그러나 경관영향평가를 위한 조망점의 선정은 모든 평가마다 기준의 일관성이 미흡하여 영향 평가 결과의 정확도와 신뢰도가 크게 저하되고 있는 실정이다. 이처럼 조망점의 위치에 따라 지각되는 경관의 모습이 현저하게 변화하게 되고, 불명확한 선정기준은 경관영향평가 결과에도 시각적 영향이 과소평가되므로 합리적인 선정기준이 필요하다. 본 연구는 개발사업 진행으로 인한 경관 변화가 예상될 때 경관영향을 평가하기 위한 객관적이고 합리적인 조망점 선정기준을 제시하고, 궁극적으로는 개발사업에 대한 경관영향 검토 및 향후 경관 모니터링을 위한 기초적인 분석방법을 제시하는데 목적을 갖고 있다. 환경영향평가서의 자연경관 내 시행되는 개발사업 중 단일건축물 및 소규모 개발을 하는 사례를 조사하고, 그 중 점적 개발사업 4곳을 대상으로 경관영향평가 부분을 분석하여 주요 조망점 선정과정에 대해 제안하였다. 기존 가시지역 분석방법의 결과인 지형 변화에 따라 가시지역 범위를 반영하지 못하는 한계를 극복하기 위해 조망 대상물 기준 가시지역 분석방법은 가시 범위를 확대하여 영향력이 높은 유효한 조망점을 선정할 수 있는 가능성을 판단하였다.

The Natural Landscape Rating System was introduced in the amendment of the NATURAL ENVIRONMENT CONSERVATION ACT in 2006. For landscape preservation, the system aims to consider the effects of development projects or plans implemented in a natural landscape on skylines, scenic resources, and view corridors. Currently, a lack of consistency in standards for determining Landscape Control Points (LCP) to assess landscape impact lowers the accuracy and reliability of the assessment results. As the perception of and the impact on a landscape varies, depending on the location of the LCP, it is necessary to establish a reasonable set of criteria to select viewpoints and avoid unreliability in the assessment due to unclear criteria. The intent of this study is to propose an objective and reasonable set of criteria for LCP selection to effectively measure the impact on the landscape from development projects that anticipate a change in the landscape and, ultimately, to suggest basic analysis methods to assess the landscape impact of development projects and to monitor the landscape in the future. Among the development projects affecting natural landscapes, as reported in the statement of the environmental impact assessment, cases of construction of a single building or other small-scale development projects were studied. Four spot development projects were analyzed in depth for their landscape impacts, in order to make recommendations for the LCP selection procedure, which aims to widen the scope of selection according to the direction of viewpoints from the target site. The existing results of analysis based on LCP have limitations because they failed to cover the viewshed of the target buildings when there are topographical changes in the surroundings. As a solution to this problem, a new viewshed analysis method has been proposed, with a focus on the development site and target buildings, rather than viewpoints, as used in past analysis.
