摘　　要：随着近年来极端气候现象的频繁出现,城市热岛效应等气候环境问题越来越受到重视。然而,当前便于城市规划应用的气候研究成果仍然十分有限。局地气候区框架基于城市形态,对城市表面的气候响应能力进行区分,为城市规划与气候信息的衔接提供了新的契机。本文以武汉为案例城市,构建城市局地气候分区图,对分区结果进行了优化和验证,并分析了武汉局地气候区的空间分布特征及其重点类别的城市形态与功能特征。经研究发现,局地气候分区框架在城市内部街区尺度上,对城市热环境异质性具有良好的区分能力。该框架中各类别用地的形态特征和功能特征揭示了其在气候敏感性城市规划与设计中的应用潜力与价值。With the increasing occurrence of extreme climate events in recent years, more attention has been paid to the urban climate issues, such as urban heat island problem. However, at present, climate research results applied in urban planning practice is still limited. Local climate zone(LCZ) scheme, classifying the urban surface based on climate response ability, provides opportunity to connect the climate information and urban planning. Taking Wuhan as a case study, this research set up the urban LCZ map, and the zoning results is optimized and verified. Subsequently, the spatial distribution of LCZs and the characteristics of functional land use and urban morphology are analyzed. The results show that LCZ scheme can differentiate the urban thermal environment appropriately at local scale. The urban functional and morphology characteristics of LCZs show application potential and great value in climate sensitive urban planning and design.
