近年来我国城市环境问题日益凸显，尤其是北方地区城市的热岛效应、沙尘天气与空气雾霾更加成为常态，在此背景下选取西安市为对象，研究北方城市的通风廊道建设方法。具体以风道建成效用为导向，借鉴国内外风道规划的先进经验，在掌握风的形成、输送与衰减等原理的基础上，通过广泛监测与实地调研，总结西安城市风环境特征与行风规律；并以城市开敞空间为依托，从分级、分类、分区、分时、分策等五方面构建城市风道体系；制定城市建成区通风性能及下垫面综合生态效益评价指标，借助计算机软件进行城区通风与地表热量变化情况模拟；以多学科视角制定城市风道建设标准，并以西安为试点，本着“旧城优化、新区控制、总体打造、局部疏导”的原则，提出各风源、风口、风廊地带的城市用地规划条件、建筑设计准则和绿地布局模式；归纳出城市风道与开敞空间的协同规划理论方法，并以“风道+”理念作为实施途径，为城市风道建设赋予更多的人居生活服务功能。

Urban environmental problems in our country have become increasingly prominent in recent years, especially in northern region China, the urban Heat Island Effect, sand and dust weather, as well as the air smog, are becoming a more normality. In this context, Xi'an is selected as a typical case and definite object at the service of the research, which is mainly about the construction method of ventilation corridor system in northern cities. To be specific, this research project is “Built Utility-Oriented”, referencing the advanced experience of wind path (air passage) planning both at home and abroad, on the basis of mastering the principles, which include the forming, transferring and attenuation of wind, through wide range of monitoring and field research, to summarize the characteristics of wind environment and regular pattern of air flow in Xi'an. At the same time, relying on the urban open space’s current status and ecological planning mode, build the urban ventilation corridor system from five aspects, which are grading, classification, partition, time-division and strategy differentiating. Establish evaluation indicators of ventilation performance in built-up area and comprehensive ecological benefit of urban underlying surface, simulate the situations of urban ventilation and surface heat change, with the help of computer software. Then setting the construction standard of urban ventilation corridor with a multidisciplinary perspective, and taking Xi' an as the pilot city, in line with the principles of “optimizing the old city, controlling the new district, generally creating and locally dredging”, in order to propose in detail the planning conditions of urban land use, architectural design criteria and green space layout mode of each wind source zone, wind offtake zone and wind path zone. Finally generalizing the collaborative construction planning theory and method of urban ventilation corridor combined with ecological open space system, and making "Wind Path plus" concept as the implementation approach, to simultaneously endow the urban wind path’s development process with more functions of serving people’ daily life.
