A Study on Botanical Garden Regeneration Strategies from the Perspective of Urban Renewal: A Case Study of the Landscape Enhancement of the Magnolia and Camellia Garden in Hangzhou Botanical Garden

Abstract

In the context of urban renewal, specialized botanical gardens, as an integral component of urban green spaces, face multiple challenges including functional revitalization, ecological optimization, and cultural reshaping. Taking the landscape enhancement scheme of the Magnolia and Camellia Garden in Hangzhou Botanical Garden as an example, this paper explores innovative paths for botanical garden design strategies from the perspective of urban regeneration. The study first reviews the development history of the Magnolia and Camellia Garden since its establishment in 1959, analyzing existing problems concerning plant varieties, supporting facilities, and spatial vitality. On this basis, it proposes a four-in-one design principle of "ecological priority, scientific layout, cultural manifestation, and interactive experience," establishing an overall positioning characterized by "beautiful scenery, exquisite horticultural techniques, and elegant style." Through strategies such as optimizing the topography and water framework, integrating the road system, enriching plant communities, and improving service facilities, the scheme achieves a dual enhancement of both the ecological environment and recreational functions of the garden. Simultaneously, by incorporating smart garden technologies, it constructs a diversified experiential space integrating popular science education and leisure activities, thereby exploring a sustainable development path for specialized botanical gardens amid urban renewal. The research demonstrates that botanical garden design integrating urban renewal concepts can not only effectively activate existing green spaces but also promote the transformation of botanical gardens from a single ornamental role to a composite function encompassing ecology, culture, and education. This provides theoretical references and practical insights for the upgrading and renovation of similar specialized gardens.
