指出了城市的主要污染物长期以来对城市居民造成了直接的危害，为更好地反映其污染变化趋势、加强污染防治工作和预防严重污染事件的发生，研究了污染预测方法，开展了污染预报工作。借助于MATLAB极强的非线性处理能力，来解决大气环境主要污染物自身复杂多变的问题，探讨了将MATLAB技术应用到空气污染的主份因子分析及预测领域中。(Pointed out that the city has long been the main pollutants of urban residents a direct harm, to better reflect its pollution trends, strengthen the prevention and control of pollution and prevention of serious pollution incidents, to study the pollution prediction method, carried out pollution forecast work. MATLAB help of strong nonlinear processing capabilities to solve complex atmospheric environment of major pollutants own issues discussed will be applied to the master copies of MATLAB technical factor analysis and forecasting in the field of air pollution.)
