摘要
首次将ISCLT模型应用在烟台市空气污染综合控制规划中。研究在进行模式验证的基础上,模拟了SO2、NOx长期平均 浓度,进行了城市空气污染特征分析及控制效果的预测。结果表明,ISCLT模型完全适用于在气象参数的获得受到限制的情况下 模拟大气污染物的长期浓度分布;部分主要高架污染源以及低架点源是烟台市SO2污染的主要来源;在市中心区,环境空气中NOx 浓度的2/3来源于机动车排放;实施综合治理方案后,区域SO2浓度基本达到国家一级标准。
It is first time that ISCLT (INDUSTRIAL SOURCE COMPLEX LONG TERM) model was applied to the study of air pollution control planning in Yantai city, Shandong Province. Based on model verification, long term mean concentration of SO2 and NO2 were simulated, analysis of contribution of different sources to the concentration in ambient air has been conducted, and the effect of control planning was predicted. Compared with monitoring values and ISCST results, errors of simulated results were less than 30%. The result showed that ISCLT was applicable to simulation of long term concentration distribution of air pollutants, even when the acquirement of meteorological data was limited. Most of SO2 concentration in Yantai urban area was from stationary sources, including both high and low point sources. Vehicle emission contributed to about 2/3 of NOX- concentration in downtown area. With implementation of comprehensive planning for air pollution control, SO2 concentration in 2010 would be decreased to 36.2ug/m3, 19.0ug/m3 at three monitoring sites respectively, almost meeting the na- tional first class standard for SO2 in ambient air.
