Abstract:Against the backdrop of global climate change and the “dual-carbon” strategy in China, to tackle the systematical problems of ecological functional degradation, concentrated carbon emissions and insufficient humanistic care in high-load transportation corridors, and taking the Shanghai Longwu Road ((Huajing Road - East Huazhan Road) Ecological Greening and Landscape Upgrading Project as an example, the innovative models and practical paths for ecological low-carbon development of high-load roads are discussed. By using the case study method, through the targeted technologies of building high-efficiency plant communities, and integrating fog forest dust suppression and soundscape masking, and taking six major theme gardens as the functional carriers, the systematic integration of ecological, low-carbon and humanistic goals has been achieved. The monitoring shows that the annual fixed carbon content of the project is increased by about 272 times, the plants and bird diversity increase significantly, and the noise and PM2.5 are reduced by 6~10 dB and 15%~25% respectively. At the same time, a composite space integrating science popularization, health and community activities is formed. The summarized innovative experience and generalizable paradigm provide the detailed practical reference and theoretical basis for green renewal and low-carbon transformation of similar roads.
