城市绿地夜景游览体验:人工照明和月光的对比

Moonlight vs.Artificial Light:A Comparative Study on Visitors'Experiences of Nightscape Within Urban Green Spaces

提高城市绿地夜景质量,从而提升人们的游览体验,对于发挥城市绿地的功能、促进居民健康具有重要作用。然而,当前设计师对于绿地夜景的关注主要集中在人工照明上,月光等自然光照几乎被忽略。本研究在11个城市绿地样地上分别拍摄了夜晚熄灯前后的对比照片,并以在校大学生为评价人员,分别评价了城市绿地熄灯前后夜景的五种游览体验。研究结果显示,无论在半月还是满月条件下,熄灯前的各种游览体验均优于熄灯后;在满月条件下,熄灯前安全性和游览意愿显著大于熄灯后,而美学价值、身心放松程度、趣味性在熄灯前后没有显著差异;在半月条件下,熄灯前后的美学价值没有显著差异,其他四种游览体验熄灯前皆显著高于熄灯后。本研究的上述结论可为在城市绿地设计中引入月光等自然光照提供理论依据。

Enhancing the nighttime environment of urban green spaces to improve visitor's experiences plays a pivotal role in realizing the full functional potential of these spaces and promoting the health and well-being of residents.However,the predominant focus of designers tends to be on artificial illumination within nightscapes,often overshadowing the consideration of natural lights such as moonlight.In this study,a total of 44 photographs of nightscapes with and without artificial lights at half-and full-moon nights respectively were taken using digital cameras at 11 sample sites of urban green spaces.Scored by college students,these photographs were assessed according to visitors'experience in five dimensions.The results indicated that at both half-and full-moon nights,the average scores of the five experience dimensions in artificial lights were higher compared with moonlight conditions.However,at full-moon night,no significant difference in aesthetic preference,relaxation,and interestingness between artificial light and moonlight conditions was found;whereas,in terms of safety and willingness to visit,the scores under artificial light condition were significantly higher than those under moonlight.At half-moon night,there was no significant difference in aesthetic preference between artificial light and moonlight conditions,but the other four experience dimensions were significantly higher under the artificial light condition.These findings provide a theoretical basis to support the reintroduction of moonlight into urban green spaces.
