Abstract
With the acceleration of urbanization, the reduction of urban green space has led to increasingly prominent ecological and environmental issues. As an effective means of ecological compensation, rooftop gardens have gradually attracted widespread attention. This study focuses on urban rooftop gardens, aiming to explore their ecological benefits and summarize key design principles. By integrating literature analysis, case studies, and field monitoring, the research systematically evaluates the role of rooftop gardens in improving microclimates, mitigating urban heat island effects, optimizing rainwater management, and enhancing biodiversity. The findings indicate that rooftop gardens can significantly reduce building energy consumption, regulate urban thermal environments, effectively retain rainwater, and alleviate urban drainage pressure. Moreover, plant selection and substrate choice are found to have a substantial impact on ecological performance. Based on these insights, this paper proposes a function-oriented design principle, emphasizing adaptability to local conditions and interdisciplinary collaboration. Innovatively, the study constructs an ecological benefit evaluation system applicable to different types of rooftop gardens, providing a scientific basis for related planning and design. The primary contribution lies in clarifying the comprehensive ecological value of rooftop gardens and offering theoretical support for their promotion and optimized design.
