城市规划与空气质量关系研究

摘要

针对城市规划与大气环境关系在定量化方面建立研究,即通过空间数据、气象数据等将城市规划、气象条件和生态环境三者相互对应,紧密结合起来,并通过精细的城市信息资料确立数学物理模型和数值计算,实现支撑技术保障.以沈阳市为例,采用不同尺度气象模式与大气化学输送扩散模式联结,运用科学合理的大气环境评估指标,建立城市规划大气环境影响评估系统,用以分析各种空气污染物对城市的影响,掌握了城市及周边地区的大气环境特征,为城市规划建设总体布局及人居环境的综合评价提供了科学依据.%This paper makes a quantitative research on the relationship between urban planning and atmosphere, which combines the urban planning, atmosphere and ecological environment through spatial data and atmosphere data with math-physics model, numeric calculation and detailed city information as the technical supports. With Shenyang as an example, by integrating the meteorological mode and chemical transmitting and spreading mode and using scientific atmospheric environment evaluation indicators, this paper sets up a system to evaluate the urban planning's effect on the atmospheric environment to analyze the influence of air pollutants on the city. The full understanding of the atmospheric environment characteristics of the city and surrounding areas would be useful to the comprehensive urban development and environment evaluation.
