摘要
利用ADMS在制作鞍山市空气污染二氧化硫数值预报研究工作中,根据对2007年1—5月逐日鞍山市6个监测点监测资料,分别选用当天浓度监测值背景值,前一天浓度监测值背景值,按比例扩大ADMS模型的预测结果,考虑背景气象条件决定的背景值,将4种背景值的方案进行污染预测比较。结果表明:以背景气象条件决定的背景值为基础实施预报,其结果的相关系数和符合指数最为显著。4种预报方案中,以考虑背景气象条件的背景值方案预报效果为最好。
Based on the daily SO2 concentration data in 6 monitoring stations of Anshan from January to May in 2007,four background values schemes were implemented to compare pollution prediction consequence by ADMS model.The different data including the intraday SO2 concentration of monitoring stations,SO2 concentration of monitoring stations in the day before,SO2 concentration amplifying prediction value in proportion by ADMS model and SO2 concentration considering meteorological conditions were respectively used as background values in four schemes.The results indicate that the scheme considering meteorological conditions is the best among four schemes.Its prediction results are reasonable and its correlation coefficient and coincidence index are also the most significant.
