摘要
从排放因子的确定、排放模型的选取和模拟结果与GIS技术结合三方面研究了城市机动车尾气排放扩散特征;总结和评述了确定排放因子的方法、排放扩散模型的发展以及国内外学者在机动车尾气排放扩散模型与GIS技术结合方面所做的工作;从数据获取、排放扩散模型的建立、计算分析、可视化等方面提出了一些改进方法。
This paper studies the characters of urban vehicle emission dispersion from three aspects： the determination of identifying emission factors, the ways to choose calculation models and the integration of GIS technology with the simulating result. It summarizes and reviews the methods to identify emission factors, the development of diffusion models and the contribution of domestic and foreign scholars on the integration of GIS technology with diffusion models. In the end it puts forward ways of improvement from the aspects of data obtaining, the foundation of diffusion models, calculation, analysis and visualization.
