【 摘 要 】

Ling Nan Tian Di block is in Fo Shan city, which is in the hot-summer and warm-winter climate area of China and is a very important scenic spot. A pedestrianized zone aims to provide a commercial and recreational center for tourists. The utilization of it is determined by the outdoor microclimate, which affects not only humans’ thermal sensation but also the commercial value; thus, putting forward the best time of day to visit this region in extreme summer is very necessary. Using the result of this work, tourists can choose the most comfortable time of day with the most suitable thermal conditions to visit this pedestrianized zone. To this end, we conducted field measurements and numerical simulations to analyze thermal sensation. In addition, a field questionnaire survey was utilized to evaluate the thermal comfort range for tourists. The analyzed result shows that the thermal comfort range of tourists is a physiological equivalent temperature (PET) of 22 to 28 °C and the neutral PET is 25 °C. The final thermal calendar shows that the whole commercial zone is within the comfort range after 7:00 p.m. During the daytime, except for the open space without vegetation, the whole region is in the comfort range from 8:00 a.m. to 10:00 a.m.
