利用ADMS模型确定各类源对本溪市空气中TSP贡献率

Analysis of TSP Contrubution Rate Using ADMS Model

采用ADMS—城市模型计算了各类污染源对市区关心点的TSP的贡献率、地方性排放源、市区无组织排放源、远距离排放源等各类污染源对本溪市区各关心点TSP的平均贡献率,结果分别约为77％、15％、8％,其中市区无组织排放源的贡献率为77％,是重点要控制的污染源。提出TSP排放的削减方案的同时,描述了实施方案后大气TSP质量改善状况。

A TSP aerial concentration numeral model in response to TSP pollution source was established by ADMS-Urban program. Average contribution ratios of point source,surface source and. flow source were calculated at each concerned spots, they were 77%,15% and 8% , Urban motor vehicle,which flow source about 77 percent,should be controlled firstly. Then some schemes to cut down TSP emission were brought out,and there improving result were predicted.
