摘要
利用灰色系统理论的灰色关联度分析法,对影响佛山市禅城区大气NO2的影响因子进行定量分析,结果表明,影响佛山市禅城区大气NO2的第一位因素是机动车密度,其次是机动车的数量;同时建立了大气NO2浓度的灰色GM(1,1)预测模型,短期预测精度很高,未来五年禅城区大气NO2浓度呈平稳下降趋势。为今后佛山市禅城区制定大气环境规划、防治大气污染提供了科学依据。
Using the gray system theory method, it is identified by correlation anlysis that the superior factors affecting the atmospheric NO2 concentration of Cheanchen district are form the density of motor vehicle and the amount of motor vehicle. And with the Gray Model GM ( 1,1 ) ,the atmospheric NO2 concentration in future five years are descending, the paper make scientific reference for planning the atmospheric environment and harnessing pollution.
