夜景照明对城市滨水环境生态—活力目标权衡的影响——以上海黄浦江徐汇滨江段为例

Impact of Artificial Nighttime Light on the Ecology-Vitality Trade-off of Urban Waterfront Environment:A Case Study of Xuhui Riverfront Section of the Huangpu River in Shanghai

选取上海市黄浦江徐汇滨江段的10个样方作为研究样本,根据文献研究建立基于生态-活力目标的夜景照明评估标准,采用适宜性评价方法量化评价各样方夜景照明照度在生态目标和活力目标两方面的达成情况,并据此通过帕累托前沿法对10个样方进行分析,结果表明,尽管不同的使用主体和活动的照度需求在数值上存在权衡关系,但可以通过合理的照度空间布局进行缓解。建议在滨水空间照明设计时,依据功能分区的需求识别进行照明布局,考虑运动活动区高照度需求影响,综合评估灯具特性针对性布设。

This paper selects 10 samples along the Xuhui riverfront section of the Huangpu River to quantitatively evaluate the achievements of nighttime lighting illumination in both ecological and vitality objectives for each sample,by using the nighttime lighting evaluation criteria established based on literature review for the ecology-vitality objectives.The results show that although there is a trade-off between the illumination needs of different use subjects and activities,it can be mitigated by a reasonable spatial layout of illumination.The study suggests that the lighting design for waterfront space should be based on the identification of functional zoning needs for lighting layout,the consideration of the impact of high illuminance requirements in sports and activity areas,and the comprehensive assessment of luminaire characteristics for targeted deployment.
