山地城市空间形态对热环境的影响

Impact on the Thermal Environment for Mountain Urban Spatial Patterns

以重庆市为例,从城市空间形态分析了山地城市布局、下垫面的热辐射特性与山地风场分布特点,及其对山地城市热环境与热岛强度的影响。利用地表红外热像图,以夏季热环境实测数据分析了山地城市不同下垫面热场的分布。提出一些有利于减弱热岛效应的建议,可为山地城市设计及山地城市旧城改造提供指导。

With the case study of chongqing,mountain city layout,ground Heat rediation characteristics and the distribution features of mountain wind field were analyzed from the urban spatial patterns,as well as its effects on Mountain urban thermal environment and urban heat island magnitude were studied.Employed ground in frared thermographs,the thermal field distributions of different ground were analyzed with field measured data of thermal environment during summer.The result can guide for mountain urban design and redevelopment.
