大气污染物浓度级别的统计与诊断判据

STATISTICAL RELATION AND DIAGNOSTIC FOUNDATION BETWEEN THE CONCENTRATION OF MAJORAIR POLLUTANTS AND WIND SPEED

利用青岛市空气自动监测系统对主要污染物 ( SO2 、NOx 和 TSP)的连续监测资料以及气象台观测的同步风向、风速资料进行统计分析 ,得出了风向、风速与污染物浓度等级的诊断判据。

Through the analysis of the data of the main air pollutants (SO 2, NO X, TSP) measured by the air pollution monitoring system and the data of wind speed and direction gained from the meteorological station, the diagnostic foundation of the statistical relation between the concentration of air pollutants and wind speed and direction were established. Comparison with the experimental data the reliability of the predicted air pollution degree according to the diagnostic foundation was 72.5%. That shows the semi quantitative relation is an easy and reliable method to forecast the air pollution degree qualitatively.
