灰色模型理论在哈尔滨市大气污染物NO_2预测中的应用

Application of the Grey System Theory in Predicting of Harbin's Atmosphere Contaminant NO_2

根据哈尔滨市大气污染物NO22002-2006年监测数据,利用灰色系统理论建立了NO2的GM(1,1)模型,对GM(1,1)模型的计算结果和精度进行了分析,并通过该模型得出了2009年NO2的预测值是0.040mg/m3。结果表明:到2009年世界大学生冬季运动会在哈尔滨召开时NO2浓度可以达到国家二级标准。

According to the monitoring data of Harbin＇s atmosphere contaminants during 2002-- 2006, a GM（1,1） Model of NO2 is built based on the Grey System Theory. The calculation results and accuracy are analyzed and the NO2 concentration by 2009 is predicted to be 0. 040 mg/m3. Consequently, by the 2009 World University Winter Games, Harbin＇s NO2 concentration will meet the Second Grade of National Standard.
