中文摘要 | In this paper the air pollution arisen from the vehicle emission in urban city is studied. It mainly includes two parts: One is to build a pollutant dispersion model for the lien source (road is expressed as the line); The other one is to build a pollutant GIS software based on the model, which is used to analyze and forecast the environmental status related to the vehicle emission in Guangzhou city. There are six chapters in the paper: chapter 1 is the foreword and chapter 6 is the conclusion. Chapter 2 to 3 are about the pollutant dispersion model. Based on the solution to the dispersion equation of continuous point source in aerodynamics, a common expression of the line-source pollutant dispersion model is gained by applying the linear system theory. Furthermore, a beeline-source model in the arbitrary wind and a circle line-source model are educed, which are the applications of the common expression. Some analysis of Guangzhou City's status of traffic and climate based on measuring data are given in chapter 4. in chapter 5, by the combination of the line-source dispersion model and GIS technique, a pollutant GIS software is developed on the basis of the electronic map of Guangzhou City, which could display the distribution of pollutant concentration arisen from the vehicles emission based on the real-time data of traffic and climate. The comparison of the simulative values with the observed data shows a favorable result. |
