Suzhou is a typical water network city,with densely woven river channels and a grid like distribution.The regulatory effect of rivers on urban thermal environment cannot be ignored.The mobile measurement method is utilized to collect thermal environment data near the riverbank in the waterfront residential area,and accurately calculate the river cooling effect of the riverbank on the waterfront residential area through the third-order polynomial and moving average methods.The research results show that the cooling effect of the river channel is the greatest m the afternoon,the average cooling effect intensity(RCI)of the river channel towards the residential area is 1.10 to 2.19 ℃ at 2 pm and the average cooling effect distance(RCD)is 32.5 to 55 meters at 2 pm.Meanwhile,data analysis is conducted on microclimate factors and measured spatial morphology data,and other influencing factors,explaining that SVF,wind speed,and greening rate have a certain influence on the river cooling effect of river channels.The research results aim to provide reference for the climate adaptive urban design of Suzhou's water network city and the future green and low-carbon development of the city.
