濟州道 沿岸域의 景觀評價에 관한 硏究

Abstract

Recently, the term, 'Amenity' has become an hot issue in urban planning and landscape field, etc. It is defined as a word, 'the right thing in the right place'. In other words, it means the people's feeling such as convenience, enjoyment, or comfort provided from some space or facilities. Unlike general urban landscape, coastal area has not only landscape but also seascape that views from land to sea. And landscape and seascape are dynamic and have been shaped over time by a combination of natural forces and human action. They will continue to evolve in the future as new demands are placed upon them. It is need to find ways to manage these demands in order that our landscape and seascape retain their value and distinctiveness. But the study for searching such ways is very rare in Korea currently. And there is no guideline or technique to evaluate the qualitative characteristics of coastal environment and landscape. When the space of coastal area is managed or designed, these evaluation techniques for assessing the coastal environment and landscape is very essential and will be more important in the near future. The main purpose of this study is four: Firstly, to present techniques for evaluating the environment and landscape features based on the concepts of 'amenity' in coastal area qualitatively. Secondly, to abstract some dominant factors which are very useful in assessing the coastal amenity and landscape. Thirdly, to classify into several clusters sharing similar characteristics of coastal landscape. Finally, to clarify the interactions between the preference trends and the dominant factors for coastal landscape evaluation. This research process will be summarized as follow: Above all, the evaluation objects and items(or words) are selected. Secondly, experimenter visited each objects(sand beaches in Jeju island) of study and took a pictures several times. Thirdly, the representative pictures were selected in each beach and a slide file for showing to subjects was prepared. Then the evaluation of the amenity and landscape in coastal area was carried out through questionnaire surveys. One is evaluated in the Likert scale and another is evaluated in the SD scale. After gathering in the same room, each subjects filled in the form of a self-administered questionnaire with keeping on sitting and watching beaches' pictures projected in white screen by beam projector. The results of questionnaire surveys were analyzed and considered through multivariate analysis such as cluster analysis and principal component analysis(PCA). Also through multiple regression analysis, the interactions between the preference trends and the dominant factors of each evaluation were clarified. The conclusions of this study were as follow: 1) As a result of the amenity evaluation, New compositional factors, called principal component, were abstracted as follows: atmosphere or refinement, safety or protection, development or accessibility, and so on. Therefore, the best beach in amenity evaluation was Hamdeok beach and evaluated very lowly in Samyang and 2nd Hwasun beaches. 2) In the aesthetic evaluation of coastal landscape, four principal components were extracted as follows: atmosphere, rurality, safety, and spatiality. Jungmun, Hyeobjea, Hwasun, Hado, Pyoseon, and Changheung-dong beaches were evaluated very highly and the worst was Samyang beach. 3) To clarify the interactions between the dominant factors' scores and the preference, multiple regression analysis was done. As a result, three factors had an effect on preference, but only rurality of them affected the preference for coastal landscape negatively.
