摘    要:采用定常高斯模式和Thlong程序建立NOx污染源强与大气NOx浓度间定量响应数值模型,计算了点源,面源和流动源等各类的污染源对杭州市区各关心点NOx的平均贡献率,分别约为17%,17%和66%,其中市区机动车尾气贡献率高达50%左右,是首先要控制的污染源。同时提出NOx排放削减方案及实施后大气NOx质量改善状况,为环保管理部门削减NO x污染源提出供决策参考。

关 键 词:大气污染  污染来源  控制对策  氮氧化物  杭州市

Abstract:An atmospheric NO\-x concentration numerical model in response to NO x pollution source was established applying fixed Gaussian model and Thlong program.The average contribution ration of point pollution source,area source and moving source was calculated at each concerned spots,being 17%,17% and 66% respectively.Among the moving sources,urban motor vehicle emission contributed 50 percent,and should be first controlled.Then some options to cut NO\-x emission were brought forward,and the improvement results were predicted.The research will provide decision\|making support to environmental protection department for NO\-x pollution source abatement in Hangzhou.
Keywords:air pollution  NO\-x pollution source  contribution ratio  controlling measure
