Abstract:In order to provide recommendations for the use and design of street space under the perspective of microclimate thermal comfort. The study, taking transitional seasons (spring and autumn) of winter city as microclimatic background and urban residential streets of Harbin for example, determines the main climatic factors and spatial pattern factors which bring big difference to microclimate thermal environment of urban residential streets in winter city. With real-time measured data testing the accuracy of simulation data as the premise, applying microclimate thermal comfort zoning method, the research conducts a preliminary analysis for relevance between microclimate thermal comfort and spatial patterns of residential streets in winter city, and on this basis proposes the corresponding optimization strategies of spatial patterns in residential streets of winter city.
