Paper Abstract

In this paper, we firstly select the streets of the old city of Harbin, which is a representative city of severe cold region, to carry out the microclimate measurement in spring. After confirming the rationality of the numerical simulation model, the numerical simulation of street microclimate in old urban area was carried out using ENVI-met software based on the measured data. The study shows that street greening has a significant effect on the microclimate of street pedestrian space. In terms of greening component, complicated greening component brings smaller wind speed, lower air temperature and higher relative humidity. Larger crown width is favorable for microclimate regulation, and the tree crown width and leaf area density have a great effect on air temperature. In view of the climatic characteristics of severe cold regions, it is suggested that trees with high leaf area density and big crown width (e.g. elm, maple) should be selected as tree species for road greening.
