摘　　要：为探究街区空间布局与空间形态特点、微气候环境和使用者环境感知之间的关系,文章基于局地气候分区理论并结合林荫空间对街道的限定,在成都市选出6条符合相应指标的街道,在冬季进行热舒适研究,结果表明:(1)在同时空下,不同LCZ分区下的街道微气候数值有差异。紧凑型街道温度波动大于开敞型;开敞型街道湿度波动范围大于紧凑型。(2)紧凑低层型街道和开敞中层型街道是最为舒适的两种街道类型。(3)人群对微气候的热感觉与热舒适具有二次线性关系,街道空间形态会对人的热偏好产生影响。(4)空间形态与行为活动会影响人的热期望与热中性范围。因此,设计时不仅需要考虑街道空间特征,还应将街道所处环境、使用群体属性及活动特征纳入考量,以创造更为舒适的街道环境。The understanding of the relationship between the spatial layout of blocks and the characteristics of spatial morphology,microclimate environment and users’perception of the environment is conducive to improving street comfort and spatial quality.This paper selects 6 streets in Chengdu City,which conform with the corresponding specifications,based on the theory of Local Climate Zone(LCZ)and the restriction of tree-shaded space,to conduct 4-day microclimate observation and user questionnaire survey in winter.The results show that:(1)Under the same space-time condition,the street microclimate under different LCZ subregions is different in value.The temperature fluctuation range of compact streets is larger than that of open streets,while the humidity fluctuation range of open streets is larger than that of the compact streets;(2)In winter,the compact low-rise street and the open middle-rise street are the two most comfortable types of street,respectively;(3)There is a quadratic linear relationship between thermal sensation and thermal comfort,and the form of street space has an effect on people’s thermal preference;and (4)The space form and the behavior activity can affect people’s thermal expectation and the thermal neutral range.Therefore,the design of street environment should consider not only the characteristics of street space,but also the environment of streets,the attributes of users and the characteristics of users’activities,in order to create a more comfortable street environment.
