城市大气污染传递函数矩阵表一定量现状分析工具

The transmission function matrix of air pollution in urban area ──an analysis tool for air pollution situation

污染源治理和大气污染总量控制的实施需要对城市进行大气污染现状的定量分析。城市大气污染传递函数矩阵表是用于确定城市污染源与关心点的大气质量的定量关系的一种方法。本文提出一个适用于不同地形条件和满足城市特点的定常高斯模式（ＬＥＥＣＭ－Ⅱ计算机程序）计算和生成污染传递函数表方法。同时给出不同城市大气质量评价中应用的结果与实测结果有相当好的相关性。结果表明：本文的模式作为大气污染现状分析工具有很强的适应性和实际情况符合较好，可广泛和方便地应用于不同的城市地区的大气污染排放总量控制和污染源规划工作中。

To make quantitative analysis for air pollution situation in urban area is required in air pollution source control and air pollution emission total control. The transmission function matrix of air pollution in urban area is a method that can be used to determine the quantitative relationship between emission sources and receptors. The constant Gauss Model(computer program LEECM-Ⅱ)of calculation and producing the transmission function matrix of air pollution for different terrain conditions and character of cities is presented in this paper. The good relativity between real measurements and calculated results by using this model in air quality evaluation of some cities is showed in the paper also. They show that the model has strong adaptability and conforms to real situation as an analysis tool for air pollution situation. It can be extensively and easily used in air pollution emission total control and air pollution source control planning in urban area.
