环境空气污染线源模式的应用研究

Astudy on Linear Source Model of Environment Air Pillution for Freeway

参照“制定地方大气污染物排放标准的技术方法”(GB/T13201—91)和“环境影响评价技术导则”(HJ/T2.1—2.3—93),建立了“公路建设项目环境影响评价规范”中推荐的线源模式的计算机应用模型—高速公路空气污染通用计算模型GAOSU。并成功地应用于“沈大高速公路污染现状研究”项目。文中详细阐述了推荐模式的合理性和实用性,肯定了它是我国高等级公路机动车尾气污染物扩散模拟计算的优选模式。对该模式中扩散参数修正、风速修正及其主要影响因素等问题提出了讨论意见。

The author have developed a linear source model of air pollution for freeway, GAOSU, based upon 'the specification of air pollution elimination', 'the guidelines of enviromentary impact evaluation 'and ''the evaluation specification of environment inference on highway construction.Some revisions on the diffusion parameters, the velocity of the wind and their infernce factors were discussed by the author in this paper.
