太原地区主要污染物污染的气象特征

Meteorological Characteristic of Main Pollutants in Taiyua

选用2002年太原地区6个环境监测站主要污染物逐时浓度监测资料和山西省观象台逐时的气象观测资料,系统的统计分析了太原地区主要污染物浓度的时空分布特征,其中包括SO2和可吸入颗粒物PM10平均浓度的逐月变化、采暖期和非采暖期平均浓度的逐时变化,以及主要污染物浓度与地面常规气象要素的相关性。揭示了各代表站主要污染物污染的年、日变化趋势、采暖期和非采暖期日变化的差异,并分析了春季大风天气时PM10与SO2污染浓度的变化特征。

Based on the consistency data hour by hour of main pollutants in 2002 in 6 environmental monitoring stations of Taiyuan and meteorological data observed by Shanxi observatory,spatio- temporal distributed characteristic of the main pollutant consistence in Taiyuan was analyzed, including S02 and PM10 average consistence changed month by month , average change when chasing of density during heating period and unheating period, the relativity between main pollutant and ground routine weather element were discovered. pollutant consistence of PM10 and SO2 in gale weather of spring was analyzed.
