It is considered the relationship between the properties of urban block and radiant environment in the street canyon from the viewpoint of the appropriate introduction of urban heat island measure technologies. Calculation methods for the radiant heat transfer between walls and roads are explained according to Gebhart's radiant absorption coefficients and Monte Carlo method. The roads are classified in the south-north road, the east-west road and the crossing. The properties of urban block are expressed by aspect ratio. A simple street canyon model and a real street canyon model are selected for the examination objects. Distribution of surface temperature and solar radiation on the roof, the road and the wall are analyzed. It is a high priority for the urban heat island measures on the roof of the building which has large roof area. The priorities of the measures on the roof and the road are higher than that on the wall. The priority of the measures on the road is high in the case that the aspect ratio W/H of the street canyon is bigger than 1.5.
