| With the rapid development of cities, the contradiction between negative impact of climate deteriorating and healthy and comfortable outdoor environment which people’s demands could have become increasingly prominent. Landscape Architecture plays an important role in urban construction, and it is also a direct way to influence the city micro-climate. In the perspective of Landscape Architecture, theories and methods designed to meet today’s climate of urgent needs. Now, For a small city streets climate research has focused on the physical environment and urban greening patterns. In recent years, The Street space form become to hotspots in Micro-climate research. Through a comprehensive measurement and analysis of the relationship between tree-lined street space type and micro-climate, preliminary analysis of the mechanism of street micro-climate, summed summarized in the form of street space and micro-climate. to provide a theoretical basis of street design.in the future.The topic of this article from Tongji University and Xi’an University of Architecture & Technology joint application of collaborative research by the National Natural Science Foundation Project: Research on Design Theory and Method of Landscape Architecture Respons to Micro-climate Suitability in Urban Livable Environment"(NO. 51338007). The Crown Dome Space on Urban Street in Xi’an is the main object of this paper. As the basic spatial units of the ribbon tree-lined space,This paper selects a representative sample of city streets as Found, to analysis the micro-climate variation measured data. During the study, the article use three methods such as theoretical research, experimental Study, quantitative and qualitative research.Theoretical research, Analysis the literature of micro-climate,Around the basicconcept of micro-climate, street,Bio-climatic Effect field, Street micro-climate effect,Evaluation of Human Comfort and so on. It provides a important Theoretical Basis to the next study.Experiment analysis,In the climate of the background of the City of Xi’an, Survey the relationship of the Green-way history and crown dome space,typical street of the city,And define the concept of crown dome space.Under direct sun obscured spatial conditions, The tree-lined street space is divided into six categories. This article choose the crown dome space the Yingnian street of east-west and Shuangrenfu street of north-south as an example to experiment, Analysis the micro-climate’ s different in summer and winter.Finally,Analysis of microclimate temperature and humidity variation of 1.5 meters from the ground under different types of tree-lined space,Mechanism of street micro-climate and summary the relations.Discussion of the proposed "single-arch" type of tree-lined street in a small space climate adaptive design recommendations, to provide a theoretical reference proposal. |
