Landscape analysis and simulation of landscaping effects in traditional building group preservation districts: A Case Study of Jindaikoji District, Unzen City, Nagasaki Prefecture

FThis study is targeting Shinshirokoji district, Kunimi-cho, Unzen city, Nagasaki prefecture. In this regard, this study paid attention to the individual objects forming the landscape and their relationships. That is, first of all, the impressions of individual objects forming the landscape were evaluated, and the relationship between the impressions of the objects was revealed. Next, the strength of each object's impression was added to the evaluation, and the overall weighted impression evaluation score of the entire district was specified. First, in this study, qualitative impressions of buildings, gardens, and walls were evaluated using the SD method in Kojirokuji, Unzen City, Nagasaki Prefecture. Second, the three types of qualification theory and cluster analysis were applied to quantitatively analyze the impression of objects and the relationship between each object. Third, weights for the impressions of all objects were introduced and the total score of impressions weighted to the entire area was calculated. Finally, we simulated the effect of hiding low-valued objects. As a result, the validity of the impression evaluation result was confirmed.
