供需视角下城市滨水空间绿色公平研究——以上海市黄浦江东岸为例

Study on the Equity of Urban Waterfront Spaces from the Perspective of Supply and Demand:A Case of the East Bank of Huangpu River in Shanghai

绿色公平主要关注城市各类绿色公共开放空间对使用群体的公平性,而滨水空间作为城市最具有活力的区域,绿色公平研究仍处于空白。本研究选取浦江东岸总长约3 km的滨水空间,从环境“供需”的视角出发,综合运用词频分析、深入访谈、问卷调查、空间语义分割等方法,从步行者、骑行者两种视角,调研环境供给和感知期望,进而计算出场地不同使用群体的公平性系数。研究结果表明,场地通过广场、分流等方式较好地协调了步行、骑行者的矛盾,但在安全性、连续性、体验性等方面更加青睐于步行者,建议针对骑行者的需求进行重点设计和补偿,提高整体公平性。

Green equity primarily concerns the fairness of various urban green public open spaces for user groups.As the most vibrant regions within a city,the research on green equity in waterfront spaces remains underexplored.This paper focuses on a waterfront area along the eastern bank of the Huangpu River,which is approximately 3 km in length.By employing methods such as word frequency analysis,semantic segmentation,questionnaire surveys,and in-depth interviews,the paper investigates environmental provisions and perceived expectations from the perspectives of pedestrians and cyclists.Subsequently,fairness coefficients for different user groups are calculated.The research findings indicate that,through methods such as plazas and diversion,the site effectively reconciles the conflicts between pedestrians and cyclists.However,in terms of safety,continuity,and experiential aspects,it shows a stronger preference for pedestrians.Therefore,it is recommended to focus on the design and compensation for the needs of cyclists,aiming to enhance overall equity.
