写真を用いた街路の緑を構成する花きの印象評価

摘要

緑は都市景観を形成する自然の具体的なイメージとなっているだけでなく、地域住民による公園や花壇の地域緑化活動や,密集市街地にみられる鉢植え緑化など社会的ネットワークの職ツーノレとしても位置付けられている。緑視率は日常生活の実感として捉えられており、国土交通省の調査では、緑視率が25%を超えると緑が多いと感じるとされている。これらを背景に、行政では、緑視率を、平成23年京都市の「京のみどり推進プラン」や同年兵庫県西宫巿甲陽園地区の地区計画で景観規制の指標として活用するなと利用が進んでいるほか、大阪府(2013)では「緑視率調査ガイドライン」が策定され、緑視率の計測方法がマニュアル化されている。%The purpose of this study is to identify the psychological effects that flowers have on people by defining the flower coverage rate and analyzing the influence of flowers on the "green coverage rate" from a respondent's peripheral viewpoint. In general, the amount of greenery is evaluated by using a quantitative index called the "green coverage rate", and flowers are handled as part of the amount of greenery. However, this study places a stronger emphasis on flower coverage rate by showing respondents some photographs in which the amount of flowers in a certain amount of greenery has been changed, and analyzes the psychological effect that these flowers have on the respondents by using the SD method. As a result of the analysis, it was found that 1)the higher the green coverage rate, respondents had towards the photograph; 2) Even when the same green coverage rate was same, the respondents had a more positive impression when the flower coverage rate was higher." and 3) as the flower coverage rate rises, the positive impression of respondents also increases especially for the SD method factors "beautiful" and "sense of the season".
