Abstract
In this study, the authors analyzed the data of thermal environmental indicators observed in typical thermal stress days in Chongqing City, an outstandingly growing megalopolis in China. And they calculated the physiological thermal indicators at several observation points with various landscapes in the city, and discussed on these temporal and spatial features from the viewpoint of urban structure around them. In the process, because it was impossible to access to electronic spatial information database such as urban planning GIS data and so on, the physiological thermal indicators calculated using observation results were compared to results of numerical simulation using the sky view photograph by fish-eye lens and Ray Man Model. Then the both results agreed well. This indicates the physiological thermal indicators have some provability to be calculated with some accuracy by simple method, even if in the field without detail electronic spatial information database. It is considered that this method is useful for evaluation of thermal environment in the area with a lack of urban spatial information database.
