Study of pedestrian road on exterior light-thermal environment in urban central district: The case of Guangzhou

Taking the greenbelt environment of pedestrian ways in urban center as the research area, compare the ecological benefits of each greenbelt with the measurement of four ecological energy indexes, such as temperature, relative humidity and illuminance of three representative roads’ greenbelt environment in Tianhe District, Guangzhou to prove that except the hard paved road, the three roads with different plant compositions all can improve city’s microclimate, especially the road with arbors planted on both sides is an effective, active way for thermal insulation and energy saving, thus producing good comprehensive benefits for energy saving. With analysis and discussion in this paper, some design thoughts and suggestions are offered to provide a theoretical basis for the study of greenbelt environment of urban walkways.
