摘要
乌鲁木齐大气污染总趋势日益严重。本文根据多年的大气监测数据,采用灰色系统理论 GM(1,1)模型预测了1989—2000年乌鲁木齐市大气颗粒物,二氧化硫、氮氧化物浓度的变化趋势。结果表明灰色系统模型对城市大气污染物浓度的预测具有一定的实用价值。
The current and advance state of air pollution in the region of ULUMUQI were deseribled in the paper.The advancing ammonts of TSP, SO_2,and NO_X in atmosphere between 1989 to 2000 were forecasted by GREY SYSTEM MODEL (GM(1,1)) basted on sampling and monitoring data.Th- e results showed that the application of GM(1,1) to the analysis and fore- casting air pollution of ULUMUQI is reasonable and reliable.
