摘要:

上海市积极深化“一江一河”建设，打造具有全球 影响力的世界级滨水空间，以绿化品质提升的“四化”建设为 引领，促进季节性景观营造，从而激发滨水空间活力。针对城 市滨水空间尺度大、范围广、数据多的特征，以人工智能赋能 下滨水秋季景观特征的全覆盖、多时相、数字化识别为核心， 以上海市黄浦江滨水空间中心城区段为例，训练滨水空间秋季 景观特征识别的深度学习算法构建语义分割模型，实现对实证 案例大批量样本数据的秋季景观特征智能化识别与测度；通过 基于位置的服务(location-based services，LBS)大数据分 析手段，量化揭示上海市黄浦江滨水空间中心城区段活力时空 分布特征。探索影响城市滨水空间活力的秋季景观特征的关键 因素，为城市滨水空间秋季景观的营造与活力激发提供理论依 据与技术支撑。

Abstract:

Shanghai actively deepens the construction of "One River, One Riverbank" while emphasizing the advancement of the "Four Enhancements" to enhance green quality. This initiative aims to create a globally influential world-class waterfront space, promoting urban ecosystem services and stimulating urban vitality. This research aims to achieve full coverage, multi-temporal, and digitized intelligent recognition for urban waterfront spaces based on artificial intelligence. Taking the central urban area along the Huangpu River waterfront in Shanghai as an example, a deep learning algorithm for identifying autumn landscape characteristics in waterfront spaces was trained to construct a semantic segmentation model. By utilizing LBS big data analysis, the spatiotemporal distribution characteristics of vitality in the central urban area along the Huangpu River waterfront in Shanghai were elucidated. This study efficiently and precisely measured the autumn landscape characteristics of a large batch of empirical case sample data, revealing key factors influencing the vitality of urban waterfront spaces. These findings provide theoretical basis and technical support for urban waterfront space renewal, reconstruction, and landscape design.
