Coupling Analysis of the Thermal Environment and Spatial Form Unit in Xinjiekou Central Area
Spatial form classification of Xinjiekou central area is divided into two levels in total—intensity and form. Intensity is selected as a major class, with height as the first limiting sub-class, and plane as the second limiting sub-class. There are 3 major classes, 12 sub-classes and 20 typical form cases in total. ENVI-met is employed to simulate the thermal environment of 20 typical cases. Set the initial conditions uniformly as follows: Wind direction: southeast; wind speed 10 m above the ground: 1 m/s; initial temperature at 7:00: 20 °C, and carry out hour-by-hour simulation for 24 h.
