The effect of greenway’s multilevel visual characters on thermal perception.

In this study, perceptual layer indicators such as light, color, plant richness, spatial openness, scenic view, thermal sensation, thermal preference were collected by questionnaire survey; and combined with the computer vision technology, green view index, sky view index, paving index, spatial enclosure, and water index were integrated. Five physical character indicators. Based on Bayesian network, the influence model of multi-level visual characters on thermal perception was constructed. The results show that visual characters affect thermal perception from both physical and perceptual levels.
