我国大规模的城市开发与建设加速了城市环境的恶化，寒冷地区大城市的雾霾现象日趋严重。为了解决现有的城市环境问题，可持续性城市建设与发展、加强生态文明建设已成为了我国的基本国策。然而，目前却缺少详细的机理研究和系统的环境导则，用以对城市开发与改造进行科学的指引。本项研究将建立在对中国现有的城市空间形态特点进行深度调查的基础上，针对寒冷地区的雾霾现象和城市空间形态，进行高解析度的城市微环境气象监测。利用中尺度和小尺度城市环境模拟，对气象监测结果进行验证分析，并使用地理信息系统，整合城市气象监测结果和城市空间形态特点信息，深度解析城市雾霾天气与城市空间形态之间的耦合性，从而验证雾霾天气的形成机理。制定空间形态因素对城市环境的影响指标，用以指导可持续性城市开发与改造。从城市规划的角度出发，对西安市现有的城市规划设计进行环境评价，为改善中国城市环境提供科学的理论根据和环境规划实施方法。

High speed urban exploring caused urban environmental problems, includes the haze weather that observed in big cities in cold climates of China. Facing to the urban environmental problems, sustainable urban development is becoming an important task in China. However, there is still a miss of mechanism study about the haze weather phenomenon, and the scientific guideline for environmental urban planning. This research will base on a deep analysis of the urban typology characters of Chinese cities, and select target districts to represent typical urban typology in cold climates, and carry out the micro-scaled urban environment measurements. Macro-scaled urban environmental simulation and micro-scaled urban environmental simulation will be used to evaluate and testify the results of the measurements. Meanwhile, GIS will be used to combine the urban weather information and urban typology information to investigate the relationship between the urban typology and the haze weather, and analysis the mechanism of haze weather phenomenon in cold climates. Demonstrate the impact of each urban planning factor on the urban environment for environmental urban development and redevelopment. From the view of urban planning, evaluate the existing urban planning of Xi’an city. This research will contributes on the methodology of sustainable urban development in Chinese cities.
