Research on optimization and biological characteristics of Harbin trees based on thermal comfort in summer

Street trees play a decisive role on creating a comfortable microclimate in summer environment. The paper provides data support for street tree species preferred, by microclimate parameters field measurements of four typical pedestrian street row planting trees, combining with Layman model fit its thermal comfort PET value, comparing human thermal comfort adjustment effect. It was also analyzed to explain the mechanisms regulating trees thermal comfort between the biomorphic characteristics of trees and microclimate parameters by using SPSS statistical analysis software. It was designed to create a comfortable space walk in the urban streets by adjusting the measured effect of thermal comfort through the trees and analysis of thermal comfort adjustment mechanism.
