Research on the Planning Methods of Mitigating Summer Urban Heat Island Effects among Basin Cities--A Case Study at Xi'an, China

Along with the process of urbanization, urban heat island effects (UHI) has become an important issue which affecting the quality of human settlements especially for clam wind basin cities. In this paper, take basin city-Xi'an as the research object, based on the actual investigation of summer environmental climate parameters in central areas of Xi'an, combined with the average air temperature distribution map of summer typical meteorological day of Xi'an. Analyze the spatial distribution of the UHI and “cool source”, the urban ventilation channel is planned initially and the mitigation suggestions of UHI is proposed.
