基于城市生物多样性保护视角下的过街天桥辅助设计策略——以济南市为例

Assistive Design Strategies for Pedestrian Overpasses from the Perspective of Urban Biodiversity Conservation—Taking Jinan City as an Example

摘要: 城市生物多样性是全球生物多样性的重要组成部分，是评价城市自然系统健康与否的重要指标之一，是维护城市的生态安全和生态平衡、改善城市人居环境的重要支撑。城市化的迅速发展对城市生态系统和生物多样性构成了严峻挑战。为了维护和促进城市的生物多样性，城市生物多样性设计已经成为城市规划和建设中的重要领域。本文围绕城市可持续发展的生物多样性议题，基于济南市区现有城市环境，推进美丽中国生态环境建设，提供更多的技术途径为目标，聚焦城市过街天桥及城市中心动植物构成要素，从栖息地多样性、植物多样性、动物多样性三个层面，探讨生物元素在过街天桥的共生方法，挖掘生态价值，让生物元素尽早回归城市中心，以更好地服务改善城市环境，试图走出一条不同城市中心过街天桥生态良性循环发展的特色之路。

Abstract: City biodiversity is an essential component of global biodiversity and serves as a vital indicator for assessing the health of natural systems within urban areas. It plays a crucial role in maintaining ecological security, ecological balance, and improving the living environment in cities. The rapid development of urbanization poses significant challenges to urban ecosystems and biodiversity. To preserve and promote urban biodiversity, urban biodiversity design has become a critical aspect of urban planning and development. This article focuses on the topic of biodiversity for urban sustainability, based on the existing urban environment in Jinan City. It aims to advance the construction of a beautiful ecological environment in China by providing more technical approaches. The focus is on urban pedestrian overpasses and the elements of flora and fauna in the city center. It explores the coexistence of biological elements on pedestri-an overpasses from the perspectives of habitat diversity, plant diversity, and animal diversity. The goal is to uncover ecological value and encourage the early return of biological elements to the urban center, thus better serving the improvement of the urban environment. The aim is to create a distinctive path for the ecological and benign development of urban pedestrian overpasses that differs from traditional approaches.
