摘　　要：目前,城市居民愈发倾向于寻求夜间的休闲活动,以缓解日间生活的压力。城市滨水公园作为城市休闲系统中重要的组成部分,发挥着重要的社会效益和生态效益。夜间光景在城市滨水公园的夜间环境中具有重要的地位。本研究以福州西湖公园为例,通过Matlab软件图像分析功能,探讨了福州西湖公园夜间光景的亮度分布特点;运用语义分析法(Semantlc Differencial,SD),从居民感知角度对公园的夜间光景进行了评价;将亮度值与评价因子作差异性分析。结果表明:(1)开化屿区域亮度最高,大梦山区域次之,谢坪屿区域最低。(2)在居民感知评价中,光色倾向、舒适度、满意度、轻松度和愉悦度均值较高,而特色度、意境感、连贯性、变化度和华丽感均值较低。(3)大梦山与谢坪屿、谢坪屿与开化屿之间的亮度差异在多数评价因子上显著,而大梦山与开化屿间的亮度差异仅在少数因子上显著。本研究为提升福州西湖公园夜间光景质量提供了理论依据。At present,urban residents are increasingly inclined to seek leisure activities at night to relieve the pressure of daytime life.Urban waterfront park,as an important part of urban leisure system,plays an important role in social and ecological benefits.Night scenery plays an important role in the night environment of urban waterfront park.Taking Fuzhou West Lake Park as an example,this study explores the luminance distribution characteristics of night scenery in Fuzhou West Lake Park through the image analysis function of Matlab software.Using the SD method,the night scenery of the park is evaluated from the perspective of residents’perception.The luminance values and evaluation factors are subjected to difference analysis.The results show that:(1)The Kaihua Island area has the highest luminance,followed by the Dameng Mountain area,and the Xieping Island area has the lowest luminance.(2)In the residents’perception evaluation,the mean values of light color tendency,comfort,satisfaction,relaxation and pleasure are relatively high,while the mean values of characteristic degree,artistic conception,coherence,variation and magnificence are relatively low.(3)The luminance differences between Dameng Mountain and Xieping Island,and between Xieping Island and Kaihua Island are significant in most evaluation factors,while the luminance differences between Dameng Mountain and Kaihua Island is significant in only in a few factors.This study provides a theoretical basis for improving the quality of night scenery in Fuzhou West Lake Park.
