摘　　要：为探讨影响苏州水乡老旧街区空间形态对室外热舒适的影响,研究选取苏州32号街坊进行现场热环境实测,发现目前冬季街巷热环境差异较大,具有可提升潜力。选取街坊内典型空间进行景观优化设计,采用ENVI-met软件,基于生理等效温度(PET)等指标,对优化后的室外空间进行模拟与分析。结果表明:(1)滨河附近区域相较于街坊内部舒适度较高,应充分发挥水域的微气候调节优势,对驳岸区域充分利用以服务于原住民和外来游客。(2)街巷内部的绿地空间微气候相对稳定,对于街坊内开阔无遮挡的硬质公共空间,较宽的道路空间应增加绿植形成一定的绿地空间以调节街巷微气候。研究结果可对改善冬季室外热环境及未来老旧街区更新设计提供参考。To study the impact of spatial morphology on outdoor thermal comfort in the old water town districts of Suzhou,on-site thermal environment measurements were conducted in Suzhou's Block NO.32.The study found significant differences in the winter thermal environment of the alleys,indicating potential for improvement.Typical spaces within the block were selected for landscape optimization design,and the ENVI-met software was used to simulate and analyze the optimized outdoor spaces based on Physiological Equivalent Temperature(PET)and other indicators.The results showed:(1)The riverside areas are more comfortable than the interior of the block,highlighting the advantage of the microclimate regulation provided by water bodies.The embankment areas should be fully utilized to benefit both residents and tourists.(2)The microclimate in the green spaces within the alleys is relatively stable.For the open,unshaded hard public spaces within the block,wider road spaces should have increased greenery to create green spaces that regulate the microclimate.These findings provide references for improving the winter outdoor thermal environment and for future redesigns of old districts.
