In the context of achieving green sustainable development through “Emission Peak and Carbon Neutrality”, this study focuses on Baotu Spring in Jinan as the research subject. It systematically analyzes the indigenous ecological low-carbon wisdom employed in the creation of its forested and architectural environment. By analyzing the water landscape system, mountain landscape system, and forest planting system, the study reconstructs the spatial pattern of Baotu Spring, characterized by “Circular Flow of the Luoshui River, Northern Mountains and Southern Water, Centralized Mountain Range, Towering Rock Formations and Dense Canopy and Lush Planting”. This reveals a “secondary nature” environmental creation system rooted in the innate natural surroundings. Building upon this foundation, the study focuses on the microclimate environments of architectural clusters within Baotu Spring, analyzing three representative cases: the “Water-island Corridor” microclimate of Luoyuan, the “Mountain stream and Waterfall” microclimate of the Li Qingzhao Memorial Hall and the “Autumn Moon over the Calm Lake” microclimate of the Wang Xuetao Memorial Hall (Cangyuan). These analyses highlight a carbon-sequestration and oxygen-release effect, driven by the mutual integration and dynamic interaction between architecture and its environment. Based on these findings, the study identifies pathways for enhancing the quality and efficiency of Baotu Spring’s landscape construction: adapting to the natural mountain-water ecosystem, integrating forested vegetation systems with the terrain, and incorporating environmental considerations into architectural design. Collectively, these insights summarize the ecological wisdom for low-carbon living embedded in the creation of Baotu Spring’s forested and architectural environment.
