본 연구는 국도의 경관구성요소인 산, 하늘, 도로포장면, 가로수, 논밭, 간판ㆍ전신주, 건물, 구조체, 비탈면, 방호ㆍ방음벽, 중앙분리대의 시각량 분석을 통하여 시대별 경관변화를 파악한 결과, 1.국도의 경관구성요소 중 각 시대별로 가장 높은 시각량을 나타낸 것은 도로포장면으로서 국도경관을 분석 평가함에 있어서 도로의 선형은 시각적으로 중요한 구성요소의 하나로 다루어져야 함을 알 수 있었다. 2.국도의 시대별 경관변화는 중앙분리대(F＝33.296)와 가로수(F＝32.881)에 의한 차이가 가장 두드러진 것으로 나타났으며, 다음 순으로는 하늘(F＝24.735)과 산(F＝23.477)이 유사한 정도의 차이값을 나타내고 있다. 그러나 건물과 구조체는 통계적으로 차이가 없음이 판명되었다. 3.국도건설은 점차적으로 자연적 요소의 감소와 인공적 요소에 의한 경관이 주를 이루게 됨을 알 수 있었다. 이는 아직까지 국도건설이 경관적ㆍ생태적 건강성을 인지하고 있음에도 불구하고 접근성과 이동성의 기능중심의 논리에서 벗어나지 못하고 있는 현실적 문제를 보여주는 결과이다.

In this study, landscape changes were examined by periods through the analysis of visual quantity on the landscape components of national road including the mountains, the sky, road pavements, street trees, paddy fields and dry fields, billboard, telegraph pole, building, structure, slope, guard fence, soundproof wall, and median strip etc. For this, subject national road in suburb arreas was selected to grasp its landscape characteristics, and divisional criteria of landscape type of the national road were suggested to look into the trend of landscape changes by periods. Findings of this study are as follows：1.Divisional criteria of landscape type of the national road include location and geometry, structure, land use, perspective, and surrounding buildings of the national road. 2.The highest visual quantity was found in road pavements by periods among landscape components of the national road. It was found that this result has a thread of connection with previous study emphasizing the importance of road geometry as one of landscape components, and road geometry shall be regarded as a visually significant component in analyzing and evaluating landscape of the national road. 3.Most distinguished factors of landscape changes of the national road by periods were median strip(F＝33.296) and street tree(F＝32.881), and then the sky(F＝24.735) and mountain(F＝23.477) showed similar level of statistically significant difference. However, statistically significance difference was not found in buildings and structures. 4.It was shown that natural elements decreased gradually but structural landscape made of artificial elements became the main in construction of the national road. This result implies that although the scenic and ecological soundness is recognized in construction of the national road, it is not out of the limitation of functionalities that is, access and mobility
