| 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；同时建立厂大气NO2浓度的灰色CM（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。

| Abstract: | Using the gray system theory method,it is identified by correlation anlysis that the superior factors affecting the atmospheric NO_2 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 NO_2 concentration in future five years are descending.the paper make scientific reference for planning the atmospheric environment and harnessing pollution. |
