視覚的様相からみた積雪寒冷地の都市景観の特徴: 札幌市中心部と小樽市中心部の冬の景観について

摘要

積雪寒冷地における都市景観の特徴を視覚的に把握する際、降雪、 積雪、融雪という変化に富んだ雪の現象は無視することはできない。 しかし、非積雪寒冷地の都市景観を扱った既往の研究と比べ、雪の 存在を重視した積雪寒冷地における都市景観の研究は極めて少ない のが現状である。そこで、積雪寒冷地における都市景観の特徴を調査、 把握していくことは、今後の積雪寒冷地に相応しい都市景観を形成 していく上で需要な課題であると思われる。%The purpose of this research was to explore the changing appearance in day and night scenes in Sapporo and Otaru area. The aspect of visual phenomena like color and light can be understood by analying the appearance of cityscape. By grasping the changing appearance of color in snowing regions, it was cleared that winter season creates different appearance particularly due to the role of the white covered. Sapporo area shows mainly straight extent scenes in day and night, but residential area from Susukino westward was turned as a dark scene without distinctive hierarchies in night. Otaru area was divided into two scenes, straight and flat extent scenes in day and night. It was showed mainly white scenes in day and black scenes in night.
