摘　　要：研究城市防治问题,采用大气污染的经典高斯扩散模型,结合气象因素对污染物浓度的影响,分别估算由污染源排放所造成的大气污染物SO2、NOx和颗粒物的浓度值,根据国家标准,分析各污染物之间的数量关系,建立模糊评价矩阵,最终划分该地区的大气污染等级。结果表明,两种方法的有效结合能够准确地得出某一污染源对该地区大气污染情况影响的综合评价。测试结果表明,符合实际情况,对大气监测有实际意义。This paper adopt Gauss Diffusion Model which is regarded as classic Air Pollution Model to evaluate the concentration of SO2 and NOx discharged by Pollutionsources separately,considering the influence that Meteorological factors affect on pollutant concentration.The quantitative relationship between different pollutants is analysed according to national standard,and the Fuzzy Evaluation Matrix for it is established.Finally,Air Pollution Level of this area is defined.The result demonstrates that the effective combination of these two methods can reach the Comprehensive Impact Evaluation for the impact of one pollution source on its area.The auther sets up one operational interface with Visual Basic Language for the system,which is more convenient to operate than often.
