大气污染偏最小二乘回归预报模型及试报分析

Report Analysis and Prediction Model on Bia Sleast Square Regression of Air Pollution

针对丹东城区SO2污染的实际情况及与气象因子的关系,建立了偏最小二乘回归预报模型,并在实际预报中进行了模拟、试报和应用、模型拟合及预报效果检验,结果发现:模型模拟值与实际值的变化趋势基本一致,模型可以用于各季SO2浓度预报。

The bia sleast square regression prediction model was established according to the relationship between the actual case of sulfur dioxide pollution and the meteorologic factors in Dandong city.Simulation,tried report and application,model fitting and test of prediction effect were carried out in the practice prediction.It is found that the running tendency of model simulated values is almost in conformity with that of actual values,and the model may be used as concentration prediction of sulfur dioxide in every season.
