The Impact of Green Viewing Rate of Urban Parks on Visitors'Thermal Comfort:A Case of Chengdu People's Park
Taking Chengdu People's Park as an example,this paper aims to explore how the green viewing rate in urban parks affects thermal comfort.Through deep learning techniques,the green viewing rate of 29 points in the park was calculated and measured.The park space was divided into four different types of square space,lakeside space,tea break space,and tree shade space.Four representative points were selected to measure microclimate factors(air temperature,wind speed,relative humidity,and solar radiation).In addition,a total of 375 questionnaires were collected for the study,detailing the subjective thermal comfort and microclimate perception of the respondents.The research results indicate that there is a significant correlation between green viewing rate and subjective thermal comfort of the tourists.The increase in green viewing rate can reduce people's perception of solar radiation,thereby enhancing subjective thermal comfort.
