摘　　要：苏州是典型水网型城市,城市河道密布如织,呈格网状分布。河道对城市热环境的调节作用不容忽视。在滨水住区河道附近采用移动测量法采集热环境数据,通过三阶多项式和移动平均法精确地计算出河道对滨水住区的缓热效应。研究结果表明:午后河道的缓热效应最大,14:00河道对住区的平均缓热强度(RCI)为1.01~2.19℃,平均缓热距离(RCD)为32.5~55 m。同时,将微气候因子与实测空间形态特征数据和其他影响要素进行数据分析,阐释了SVF、风速和绿化率对河道缓热效应具有一定的影响。研究结果可为苏州水网型城市的气候适应性城市设计和未来城市绿色低碳发展提供参考。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 in 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.
